Cross-linked polyethylene insulated cable: OMG demonstrates superior quality with strength

China [CN]

Cross-linked polyethylene (XLPE) insulated cable is a core product in modern power transmission. Using polyethylene as its base material, the molecular chains are cross-linked into a network structure through physical (electron beam irradiation) or chemical (peroxide cross-linking) methods. This significantly improves material performance: its heat resistance rating leaps from 70°C (standard polyethylene) to 90°C-125°C, with a long-term operating temperature of 90°C and a short-term overload temperature of up to 140°C. Its current carrying capacity is approximately 30% higher than that of oil-paper insulated cables of the same specification. Its insulation layer exhibits excellent electrical strength (breakdown field strength ≥30kV/mm), mechanical toughness (elongation at break ≥250%), and chemical stability. It is resistant to acid and alkali corrosion and stress cracking, and its compact and lightweight structure makes it easy to lay and install.

This cable is widely used in power distribution for new energy electric vehicles (AC1000V-DC1500V), high-voltage wiring harnesses for new energy vehicles, and power connections for industrial equipment. For example, in new energy vehicles, XLPE insulated cables can meet the power transmission needs of high-voltage systems above 600V, and their shielding design can resist electromagnetic interference. In the power grid sector, their halogen-free flame retardant properties (oxygen index ≥ 28) meet environmental requirements, and their maintenance-free life of over 30 years makes them a preferred alternative to traditional oil-impregnated paper insulated cables. With their stable performance and high cost-effectiveness, XLPE insulated cables are continuously driving the upgrade of power transmission towards efficiency, safety, and environmental protection.
