WDZB-BYJ4 square heat-resistant 105 degree cross-linked polyolefin insulated wire

Description :

This product is WDZB-BYJ copper core cross-linked polyolefin insulated wire, which is a high-performance and environmentally friendly building wire. Its core advantage lies in the use of advanced irradiation cross-linking technology, which upgrades the insulation material from ordinary PVC to cross-linked polyolefin, thereby increasing the long-term allowable working temperature to 105 ℃, far higher than the 70 ℃ of ordinary wires. This characteristic enables it to maintain excellent electrical performance and mechanical strength even in high temperature environments, effectively preventing safety hazards such as insulation aging and short circuits caused by overheating.

WDZB "stands for halogen-free low smoke flame retardant Class B, which means that it will not produce a large amount of toxic and harmful halogen gases and thick smoke during combustion. It has high transparency, greatly improving the escape probability and fire rescue efficiency of personnel in case of fire. It is particularly suitable for public places with strict requirements for fire safety. The conductor is made of high-purity oxygen free copper, with low resistivity, stable conductivity, and high energy efficiency. The insulation layer has a bright color (as shown in blue, usually used for neutral wires), uniform thickness, and good acid and alkali resistance, oil and oil resistance, and UV resistance.

This product is widely used for power transmission and lighting line laying in high-rise buildings, subways, tunnels, hospitals, schools, shopping malls, data centers, and residential projects. It can be used for concealed installation of pipes or exposed installation of cable trays, making it an ideal choice for modern green and intelligent buildings. Compliant with relevant national standards such as GB/T 19666 and JB/T 10491, with reliable quality and long service life, it is a high-quality basic material that ensures electrical safety and meets environmental standards.
