Wind power cable CPE sheathing compound

This product is produced according to national standard TICW/01-2009 flexible and torsion-resistant cables of rated voltages up to and including 1.8/3KV for wind turbine and can adapt to special working environment of wind power station for features such as excellent flame retardance, low temperature resistance, low smoke, good shock resistance and irradiation resistance. It is mainly used in ethylene-propylene insulated flexible CPE single-core sheathed cables for wind power generation of AC rated voltages up to and including 12/20kv.
