What is the difference between XLPE cable and PVC cable?

I. What is the difference between XLPE cable and PVC cable? 1. Low-voltage cross-linked (XLPE) cables have developed rapidly since they were put into application in the mid-1990s, and now each accounts for half of the market share with polyvinyl chloride (PVC) cables. Compared with PVC cables, cross-linked cables have higher current-carrying capacity, stronger overload capacity, and longer service life (the thermal life of PVC cables is generally 20 years when the environment is good, while the thermal life of XLPE cables is generally 40 years); PVC decomposes and releases a large amount of black smoke and poisonous gases when it burns, while XLPE does not produce halogenous poisonous gases when it burns. The superiority of cross-linked cables is increasingly recognized by the design and use departments. 2. When ordinary PVC wires and cables (insulation and sheaths) burn, they ignite rapidly, fuel the fire, and lose the ability to supply electricity in 1 to 2 minutes, and the black smoke released by their combustion and decomposition can reach a level that is impossible to see, which makes it difficult for people to breathe and evacuate. More seriously, PVC combustion will decompose and release hydrogen chloride (HCL) and dioxin and other highly toxic corrosive halogen gases, is the main cause of death in the fire (accounting for 80% of the fire deaths), and into the dilute hydrochloric acid conductive film attached to electrical equipment, seriously reducing the insulating properties of the equipment, the formation of secondary disasters difficult to remove.
