The Difference Between XLPE Cable And PVC Cable

 The difference between XLPE cable and PVC cable


1. Low-voltage cross-linked (XLPE) cables have developed rapidly since they were put into use in the mid-1990s, and now they share half of the market with polyvinyl chloride (PVC) cables.
Compared with PVC cables(4 core 6mm flexible cable、flexible cable 240mm2、multicore flexible cable...), cross-linked cables have higher carrying capacity, stronger overload capacity and longer service life (the thermal life of PVC cables is generally 20 years when the environment is good, and the thermal life of XLPE cables(16mm armoured cable 3 core、250mm2 xlpe cable is generally 40 years); When PVC is burned, it will decompose and release a lot of black smoke and toxic gas, while XLPE will not produce halogen toxic gas when burned. The superiority of cross-linked cables is increasingly recognized by design and use departments.

2. Ordinary PVC wires that cable acerado flexible、flexible welding cablepvc insulated single core flexible copper cable and cables (insulation and sheath) burn quickly, fueling the fire, losing power supply capability within 1 to 2 minutes, and the black smoke released by burning and decomposing can reach the level where you can't see your fingers, making it difficult for people to breathe and evacuate .
What's more serious is that when PVC burns, it will decompose and release highly toxic and corrosive halogen gases such as hydrogen chloride (HCL) and dioxin, which is the main cause of death in fires (accounting for 80% of fire death factors), and forms dilute The hydrochloric acid conductive film adheres to the electrical equipment, which seriously reduces the insulation performance of the equipment and forms a secondary disaster that is difficult to remove.
