Film-covered wire, also known as Mylar wire, refers to the reinforced insulating magnet wire which is wrapped with one or more layers of insulating film outside the ordinary stranded wire according to a certain overlap rate. It has the advantages of good insulation performance and high mechanical strength; Good voltage resistance, product working voltage up to 1000V; good high-frequency performance, good high-frequency performance, operating frequency up to 500kHz; good heat resistance; radiation resistance (PI film); can be widely used in various high-frequency high-voltage power conversion equipment . This product is specially designed to meet high temperature and high pressure, and has certain flame retardant and waterproof effects to meet the requirements of harsh working environments
