●Product Introduction

Film sintering wire has the features of thin insulation layer, high insulation strength, good toughness property, good heat resistance property, good waterproofness property and so on. It is widely used in all kinds of high-voltage and high-power electric motor windings, and those under high temperature and high humidity environment. Using corona resistance film sintering wire can also improve insulation layer’s corona resistance ability, impulse voltage resistance ability and heat dissipation ability. The corona resistance film sintering wire can be used to manufacture windings of variable frequency motors, traction motors and high voltage motors.
