Application of Irradiated Wires in Motor Vehicles

The use of irradiation - crosslinked wire for internal wiring has been increasing year by year due to requirements for safety and space reduction of electronic equipment. Also, in the case of motor vehicles, flame retardance, long life, weight reduction, and high reliability of insulation materials hare recently become important requirements.

Our test results show that irradiation - crosslinked flame-retardant polyethylene-insulated wire rated at 150°C can pass the vertical flame test requirement and, if surrounded by ordinary PVC wires in wiring harnesses, can reduce damage to the PVC wires because it does not flow under over-current load. Additionally, irradiation-crosslinked PVC wire has been as certained to be outstandingly stable under over-current load and to have high reliability even at low temperatures.
