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.
