XLPE cable
XLPE cable refers to a cross-linked polyethylene insulated aluminum core armored cable. In the XLPE cable, the aluminum stranded wire is first shielded in the form of semi-conductive extrusion. The aluminum stranded wire can provide a smooth conductor surface and prevent a cavity from forming on the conductor surface when the cable is bent. The shield conductor is insulated with extruded XLPE compound. The insulating layer is further shielded with a non-metal semiconductor material layer, and a non-magnetic metal shielding layer in the form of copper or aluminum tape is applied thereon. If it is a multi-core cable, put the core wire together with a suitable filler in the gap and wrap it with PVC tape or extruded PVC. For mechanical protection, non-magnetic aluminum wire/tape/tape armor for single-core cables and steel wire armor for multi-core cables are provided on the inner sheath. Extrude a layer of PVC/PE as the outer jacket, usually with the back color to prevent moisture from entering.

What is the difference between XLPE and PVC insulated cables?
XLPE is cross-linked polyethylene. The cross-linking or vulcanization process involves the creation of chemical bonds at the intervals between long molecular chains to produce a "staircase" effect that prevents slippage between molecules. As a result of crosslinking, the material becomes heat resistant and does not soften at high temperatures. It can resist stress cracking and aging. As the structure changes, XLPE has obtained excellent electrical properties. Compared with PVC cables, XLPE cables have higher rated current and longer service life. Under short-circuit conditions, the cable can withstand temperatures up to 250ºC compared to the 160ºC of PVC cables.
In emergency situations, it also has a higher overload capacity. XLPE cable is an ideal choice for power transmission and distribution, because it has high corrosion resistance in contaminated atmospheric environment, and has better resistance to chemicals and corrosive alkali. Not only that, it can also withstand vibration and thermal shock. Compared with PVC, its moisture resistance is 100 times higher.
