XLPE insulated power cable

Cross-linked polyethylene XLPE has stable intermolecular bonds between polyethylene particles produced by thermochemical action due to the presence of organic peroxides.

XLPE has the same electrical properties as conventional polyethylene, and has better thermal and mechanical properties due to stable intermolecular bonding. This makes the maximum continuous conductor temperature of XLPE insulated cables 90°C, while the maximum continuous conductor temperature of conventional polyethylene insulated cables is 75°C. The maximum working temperature of the overload conductor is 130°C (under the emergency overload temperature, it shall not exceed 100 hours per year). The maximum conductor short-circuit temperature is 250°C. This provides important advantages in terms of cable ratings and has special significance in countries or situations where the ambient temperature is high and a derating factor must be applied.

The cross-linking technology is completely based on the "dry" cross-linking and cooling process. This eliminates the tiny inclusions of water in the insulation, which, unless prevented, will cause the so-called "water tree effect". The triple cross head can extrude the shielding layer over the conductor and extrude the shielding layer over the insulating layer in one technical operation. All these make the cable have excellent electrical, thermal and mechanical properties.
