What is the difference between XLPE and PVC?

Compared with PVC cables, XLPE cables have higher current carrying capacity, stronger overload capacity and longer service life. When the environment is good, the thermal life of PVC cables is generally 20 years, and the thermal life of XLPE cables is generally 40 years.

When PVC burns, it will decompose and release a large amount of black smoke and toxic gases, while XLPE will not produce halogen toxic gases when burned. The superiority of cross-linked cables is increasingly recognized by the design and use departments.

Ordinary polyvinyl chloride wires and cables (insulation and sheath) burn fast and contribute to fires. If the power is cut off after 1~2min, the black smoke released by the burning and decomposition can reach the level of invisible, which makes it difficult for people to breathe and evacuate. What’s more serious is that when PVC cable burns, it will decompose and release highly toxic and corrosive halogen gases, such as hydrogen chloride (HCL) and dioxins, which are the main cause of death in fires (accounting for 80% of fire deaths) and become The rare hydrochloric acid conductive film is attached to the electrical equipment, which seriously reduces the insulation performance of the equipment and forms a secondary disaster that is difficult to remove.
