Custom N2XY XLPE Insulated Power Cable 25Sq mm Environmental Protection
XLPE is Cross-linked Polyethylene.. The process of cross-linking or vulcanisation consists of producing chemical bonds at intervals between the long molecular chains to give a “ladder” effect which prevents slippage between molecules. As a result of cross-linking, the material becomes heat resistant and does not soften at high temperatures. It develops resistance to stress cracking and ageing . With the change in structure, the XLPE derives superior electrical properties. XLPE Cables have higher current rating and longer service life compared to PVC Cables. Under short circuit condition,this cable can withstand up to 250ºC temperature compared to 160ºC for PVC cables.

XLPE is suitable for voltage ranges from low to extra high voltage, surpassing other insulation materials such as PVC, Ethylene Propylene Rubber (EPR) and silicone rubbers. Cross-linking the polyethylene also enhances the chemical and oil resistance at elevated temperatures and makes it suitable for use as a Low Smoke Zero Halogen material.
