Continuous advancements in testing equipment and technology have made quality control of cables more precise. In addition, environmental protection and sustainable development requirements also encourage manufacturers to adopt renewable materials and eco-friendly production processes.   In short, cable is the silent hero of our modern world. They connect people and devices, and drive the development of technology. We should pay attention to the latest developments in the field of cables and constantly pursue innovation to meet the growing technical needs.

The control electrical system is suitable for polyoxyethylene insulated and polyethylene sheathed control electrical systems used in industrial and mining enterprises, energy transportation departments, and for control and maintenance lines with AC rated voltages below 450/750 volts. Extra voltage: U0/ is 450/750v. Computer cables are suitable for computers and automated power-saving systems with rated voltages of 500v and below that require high anti-scan components. The insulation of the electric ground wire flower adopts K-type Class B low-density and E-burning with anti-oxidation function. Polyethylene has high insulation resistance, good deformed voltage, small dielectric impurity and little influence on dielectric loss, temperature and frequency. It can not only meet the requirements of transmission performance, but also ensure the service life of the cable.   In order to reduce mutual crosstalk and internal interference between circuits, the electrical system adopts a shielded structure. The shielding requirements of the electrical system are adopted according to different situations: continuous combined screen, total shielding of the electrical system composed of lines, total shielding after the combined shielding of the textile and other methods. There are three types of shielding materials: round copper wire, copper tape, aluminum tape, and seat material composite tape. The shielding pair and the shielding pair have good insulation properties, so if a potential difference occurs between the shielding pairs during use, the signal transmission quality will not be affected. The temporary service temperatures of conductor wires are 70°C and 105°C, and the normal laying temperature should not be lower than 0°C.   1. The insulation levels of the two are different. In absolute terms, the insulation level of control cables is slightly higher. Control cable insulation is generally 450/750V.   2. Computer cables relatively emphasize the shielding effect and have stronger anti-interference performance. Most of them adopt the method of partial shielding + total shielding.   3. Control cables have higher machine strength and tensile strength than computer cables, especially those with steel armor. Suitable for indoor digital installation or even underground installation. The computer electrical system is slightly weaker in strength and not tensile-resistant, and is generally only laid outside the substation or cabinet room.   Many manufacturers don't know what's going on. They use the standards of control electronics to manufacture communication systems. Not only do the produced electronics look stupid, but they can't be matched with communication parameters! The industrial automation system is developing rapidly, and computer electronics designed in the past are The system cannot meet the requirements! Nowadays, the industrial fieldbus with R5485/RS422 interface has gradually replaced the traditional dashboard-type control system. It is not only complex in structure, but also easy to maintain and facilitate networking.   There are essential differences between control electrical systems and computer electrical systems. When purchasing this type of electrical system, you should ask the customer service staff clearly to prevent problems.

Mechanical separation method 1) Drum peeling machine processing method. This method is suitable for processing waste wires and cables of the same diameter. This equipment already exists in our country. The Wolverhampton factory in the UK uses this kind of equipment to strip waste wires and cables, and the results are very good. A. Copper and plastic in waste wires and cables can be comprehensively recycled, with a high level of comprehensive utilization; C. The process is simple and easy to mechanize and automate; 2) Cutting type peeling machine processing method. This method is suitable for processing thick cables and wires, and a factory in Xiangfan, my country has been able to produce this equipment.   Low temperature freezing method The cryogenic freezing method is suitable for processing wires and cables of various specifications. The waste wires and cables are first frozen to make the insulation layer brittle, and then crushed by shock to separate the insulation layer from the copper wires.   Chemical peeling method This method uses an organic solvent to dissolve the insulation layer of the waste wire to achieve the purpose of separating the copper wire and the insulation layer. The advantage of this method is that it can obtain high-quality copper wire, but the disadvantage is that it is difficult to process the solution and the price of the solvent is high. The development direction of this technology is to research a cheap, practical and effective solvent; recommended product: control cable   Thermal decomposition method The waste wires and cables are first sheared, and then added to the pyrolysis chamber for pyrolysis by the transport feeder. The pyrolyzed copper wires are sent to the outlet sealing pool by the grate conveyor, and then loaded into the product collector. The copper wires It can be used as raw material for producing refined copper. The gas produced by pyrolysis is sent to the afterburning chamber to burn the combustible substances in it, and then sent to the reactor to absorb the chlorine gas with calcium oxide and then discharged. The generated calcium chloride can be used as a building material.  

The full name of BV wire is copper core PVC insulated PVC sheathed round sheathed wire, also known as light PVC sheathed cable, commonly known as hard sheathed wire. Copper core (hard) cloth wires, single-core ones are round, and double-core ones are flat. Often used for surface-mounted wires.   The letter B stands for cloth wire, and the letter V stands for polyvinyl chloride in plastic. There are also copper core symbols and hard wire (common single-core conductor) symbols that are omitted and not indicated.   The difference between BVV and BV lines is that BVV has one more layer of sheath than BV. Suitable for cables and wires used in power equipment, household appliances, appearance and telecommunications equipment with AC voltage 450/750V and below. The wire core is allowed to have an operating temperature not exceeding +65 degrees for a long time. Its nominal cross-section is divided into seven specifications from 0.75 to 10 square meters: 0.75; 1.0; 1.5; 2.5; 4; 6; 10;   Suitable for cables and wires used in power equipment, household appliances, appearance and telecommunications equipment with AC voltage 450/750V and below.

YJV cables and VV cables are basically the same in function, but their differences are also obvious. There are three main ones: 1. Different names of products have different meanings: YJV cable insulation uses cross-linked polyethylene, and VV cable insulation uses polyvinyl chloride. 2. The two lines also have differences in production equipment and process manufacturing: VV is plastic cable, YJV is cross-linked cable, and its insulation layer performance is better than plastic cable. YJV only performs cross-linking treatment on the insulating material to increase the heat resistance temperature, but VV does not. The working temperature of YJV cable reaches 90 degrees, while VV is only 70 degrees. YJV cable with the same cross-sectional area has a large carrying capacity. The maximum rated operating temperature of VV cable conductors is 70 degrees Celsius, and the maximum temperature during short circuit (duration less than 5 seconds) does not exceed 160 degrees Celsius. The maximum rated operating temperature of YJV cable conductors is 90 degrees Celsius, and the maximum temperature during short circuit (duration less than 5 seconds) does not exceed 250 degrees Celsius. YJV is better than VV in the long run (longer service life, etc.), but it is more expensive than VV. From the perspective of the maximum allowable short circuit height: YJV is 250 degrees, VV is 160, 140 degrees. The application environment of YJV is worse than VV in terms of waterproofing. If it is laid underground, VV cable should be used. When using YJV, it is necessary to ensure that the cable is not soaked in water, that is, to ensure that the cable trench (well) has good drainage. If the cable tray is laid, YJV is selected. From the perspective of technical and economic indicators, the three-core YJV cable has higher parameters than the VV cable. It is recommended to use YJV in civil buildings. Its carrying capacity is larger than that of VV. More importantly, in the event of an electrical fire, because its insulation material does not contain chlorine, it will not produce toxic gases when burned. So that means VV’s environmental performance is worse. In civil, nuclear power and other fields, VV has been basically replaced by YJV. However, in many industrial enterprises, VV is still widely used because of its low price. Because YJV cable is better than VV cable in terms of cost performance, YJV cable has a tendency to replace VV cable.  

If you have any needs, please contact us! Let’s take a look at the six major points that you need to pay attention to in wires and cables.   1) Insulation damage causes short circuit failure. The protective lead sheath of the power cable is damaged during laying or the cable insulation is mechanically damaged during operation, causing insulation breakdown between cable phases or lead sheaths. The generated arc causes the insulation material and the outer protective layer material of the cable to burn and catch fire.   2) The cable is overloaded for a long time. After long-term overload operation, the operating temperature of the cable insulation material exceeds the allowable temperature of normal heating, causing the cable insulation to age and dry out. This phenomenon of insulation aging and drying usually occurs on the entire cable line. As the cable insulation ages and dries up, the insulation material loses or reduces its insulation and mechanical properties, making it prone to breakdown and fire, or even multiple simultaneous fires along the entire length of the cable.   3) Oil-immersed cables may drip or leak due to height differences. When the oil-immersed cable is laid with a large height difference, oil dripping from the cable may occur. As a result of the flow, the upper part of the cable dries up due to the loss of oil. The thermal resistance of this part of the cable increases, causing the paper insulation to coke and cause premature breakdown. In addition, since the oil in the upper part flows downward, space is created at the upper cable head and negative pressure is generated, making the cable easy to absorb moisture and causing the end to become damp. The accumulation of oil in the lower part of the cable produces a large static pressure, causing the cable head to leak oil. Cable moisture and oil leakage increase the chance of failure and fire.   4) The insulation breakdown of the intermediate joint box. Due to loose crimping, weak welding, or improper selection of joint materials, the middle joint of the cable joint box will oxidize, heat, and flow during operation; when making the cable middle joint, the quality of the insulating agent poured into the middle joint box does not meet the standards. It is required that when pouring insulating agent, there are air holes in the box and the cable box is poorly sealed or damaged and moisture leaks in. The above factors can cause insulation breakdown, form a short circuit, and cause the cable to explode and catch fire.   5) The cable head is burning. Due to moisture and dirt on the surface of the cable head, the porcelain sleeve of the cable head is broken and the distance between the lead wires is too small, causing flashover and fire, causing the surface insulation of the cable head and the lead wire insulation to burn.   6) External fire and heat sources cause cable fires. Such as the spread of fire in the oil system, the spread of oil circuit breaker explosion fire, the spontaneous combustion of pulverized coal in the boiler pulverizing system or coal conveying system, the baking of high-temperature steam pipes, chemical corrosion of acids and alkalis, welding sparks and other fires, all can cause cable damage. produce fire

Generally speaking, power cables mainly include disconnection faults, grounding or short-circuit faults, disconnection and grounding faults, flashover faults, etc. We can determine the fault type of power cable according to some of the following methods. An insulation resistance meter is needed here. For wires and cables, place the insulation resistance meter at one end of the line to measure the insulation resistance of each phase.   1) When one or more cores of the shake measuring cable are discontinuous and are grounded through a resistor, it can be judged to be a disconnection and ground fault.   2) When the insulation resistance of one or several cores of a cable to the ground is measured remotely, or the insulation resistance between cores is much lower than the normal value, but higher than 100 kiloohms, it is a high resistance ground fault.   3) When the insulation resistance of one or more cores of the shaking cable to the ground is high or normal, a conductor continuity test should be conducted to check whether there is any disconnection. If so, it is a disconnection fault.   4) When the insulation resistance of one or several cores of a cable to the ground is measured remotely, or the insulation resistance between cores is less than 100 kiloohms, it is a low-resistance grounding or short-circuit fault.   5) Flashover faults often occur in preventive withstand voltage tests, and most of them occur at cable terminals and intermediate joints. Flashover sometimes occurs multiple times in a row, each time separated by seconds to minutes.   The instruments and equipment used in the past include QF1-A cable detector, DLG-1 flash detector, cable path meter and fault location meter, etc. The current popular test method is the flash test method, which includes flash and direct flash, and the flash test method is commonly used. The flash test has high accuracy, simple operation, safety and reliability. Its equipment mainly consists of two parts, namely high-voltage generating device and current pulse meter. The high-voltage generating device is used to generate DC high voltage or impact high voltage, which is applied to the faulty cable to force the fault point to discharge and generate a reflected signal. The current pulse meter is used to pick up reflected signals to measure fault distance or directly use low-voltage pulses to measure open circuits, short circuits or low resistance faults.

Cable wires are an essential component of modern electrical and communication systems, enabling the efficient transmission of signals and power. But have you ever wondered what cable wires are made of?   Cable wires are typically composed of several layers, each serving a specific purpose. The core material is usually copper or aluminum, known for their excellent conductivity. Copper is the most common choice due to its superior conductivity and resistance to corrosion. Aluminum is a cost-effective alternative but has slightly lower conductivity.   The core is surrounded by an insulating layer, which prevents electrical leakage and ensures the safety of the wire. Common insulation materials include PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), and rubber. PVC is widely used for its affordability and versatility, while XLPE is preferred for its superior resistance to high voltages and temperatures.   To provide mechanical strength and protect the conductor, cable wires are further encased in an outer jacket or sheath. Materials like PVC, polyethylene, or synthetic rubber are used for this purpose. The jacket also helps to shield the wire from moisture, chemicals, and physical damage.   In specialized applications, such as fire-resistant or submarine cables, additional materials are incorporated. Fire-resistant cables are designed with insulation that can withstand high temperatures, while submarine cables are armored and waterproofed to withstand the harsh underwater environment.   The composition of cable wires can vary depending on their specific application, such as power transmission, telecommunications, or data networking. Different industries and regions may have their own standards and regulations regarding cable wire materials.   Understanding what cable wires are made of is crucial for selecting the right type of wire for a particular purpose, ensuring reliable and efficient performance. Manufacturers and suppliers continually research and develop new materials to enhance the properties of cable wires, resulting in improved conductivity, insulation, and durability.   In conclusion, cable wires are typically made of copper or aluminum conductors, insulated with materials like PVC or XLPE, and protected by an outer jacket or sheath. The selection of materials depends on the intended application of the cable wire, ensuring optimal performance and safety in various industries and environments.

Fire-resistant cables are mainly used in power supply circuits from emergency power supplies to user fire protection equipment, fire alarm equipment, ventilation and smoke exhaust equipment, navigation lights, emergency power sockets, emergency elevators, etc.   Workers need to pay attention to the following issues when installing fire-resistant cables When fire-resistant cables are used in cable fermentation tunnels, cable interlayers with dense cables, or in flammable places such as near oil depots, Class A fire-resistant cables should be selected first. Except for these situations and when the number of cable configurations is small, Class B fire-resistant cables should be selected.   Fire-resistant cables are mostly used as power supply circuits for emergency power supplies and are required to function normally in case of fire. Since the ambient temperature rises sharply during a fire, in order to ensure the transmission capacity of the line and reduce the voltage drop, for circuits with long power supply lines that strictly limit the allowable voltage drop, the cross-section of the fire-resistant cable should be enlarged by at least one level.   Fire-resistant cables cannot be used as high-temperature resistant cables.   In order to reduce the probability of cable joint failure in a fire accident, the number of joints should be minimized during installation to ensure that the line can work normally in a fire. If branch wiring is required, the joints should be fireproofed.
