Medium Voltage XLPE Insulated Power Cable Single Core / 3 Core Copper Conductor XLPE Insulated Cable N2XSY
XLPE, Cross-linked polyethylene, has stable intermolecular bonds between polyethylene particles created by thermochemical action, due to the presence of organic peroxide.
XLPE has the same electricl properties as the conventional polyethylene and as result of stable intermolecular bonds, has much better thermal and mechanical properties. This provides XLPE insulated cables to be used at maximum continuous conductor temperature of 90°C while conventional polyethylene insulated cables to be used at that of 75°C. Maximum overload conductor operating temperature is 130°C ( operating at the emergency overload temperature shall not exceed 100 hours per year). Maximum conductor short-circuit temperature is 250°C. This provides an important advantage in cable ratings and is of special significance in countries or situations where the ambient temperature is high and derating factors have to be applied.
