The processing and production of bare conductor are carried out in accordance with the national standards. The latest domestic standard is: GB/T1179-2008. The relevant national standards used before are no longer used. Since the previous standards are relatively simple and clear, refer to It is very convenient to use. Except for the change in the … Read more

1 The difference in principle Fire-resistant cables have different principles from flame-retardant cables. The flame-retardant principle of halogen-containing cable is based on the flame-retardant effect of halogen, and the flame-retardant principle of halogen-free cable is to reduce the temperature of the water to extinguish the fire. Fire-resistant cables rely on the fire-resistant and heat-resistant characteristics … Read more
Cross-linked cable is short for cross-linked polyethylene (XLPE) insulated cable. Cross-linked cables are suitable for transmission and distribution lines with power frequency AC voltage of 500KV and below. At present, most of the high-voltage cables have been used for cross-linked polyethylene insulated cross-linked cables, which usually means that the insulation layer of the cable is … Read more
What is XLPE cable? The cross-linked polyethylene(XLPE) insulated cable uses peroxide cross-linking method to change the polyethylene molecule from a linear molecular structure to a three-dimensional network structure, and from a thermoplastic material to a thermosetting material. The working temperature is increased from 70°C to 90°C. Improve the current carrying capacity of the cable; What … Read more
XLPE power cable has good electrical and corrosion resistance. It is easy to install and easy to operate and maintain. It is widely used in 10 kV rural distribution networks. However, once it fails, it is difficult to repair and find. Combining the actual operation and work, focus on the analysis of the principle and … Read more
Overhead lines mainly refer to overhead cable, erected on the ground, and are transmission lines that use insulators to fix transmission wires on poles that stand upright on the ground to transmit electrical energy. Overhead lines have low cost, strong mobility, and easy maintenance. However, overhead lines hinder traffic and construction and are easily polluted … Read more
Overhead power lines mainly refer to overhead electrical wires, erected on the ground, and are transmission lines that use insulators to fix transmission wires on poles standing upright on the ground to transmit electrical energy. What type of wire is used for overhead? The wires used in low-voltage overhead lines are divided into bare wires and insulated wires. According to the structure … Read more
1.What are the types of cable? The wire products used to transmit electric (magnetic) energy, information and realize the conversion of electromagnetic energy are collectively referred to as wires and cables. According to different purposes, wires and cables can be divided into five categories: (1). Bare conductors: products with only conductors without insulation, such as … Read more
The advent of power cables has greatly improved the safety of power generation, transmission, transformation, supply, distribution, and use of electricity. Single-core power cables appeared first. As there are more and more occasions for three-phase four-wire power supply, three-phase five-wire power supply and multi-loop power supply in actual use, the requirements for occupied space and … Read more
