0.13mm-1mm Custom High Voltage Triple Insulated Wire for Transformer Windings
What is triple insulated wire?
Triple insulated wire is a high performance insulated wire consisting of three insulating materials. The middle is a pure copper conductor,thefirst and second layers of this wire are PET resin (polyester-based materials), and the third layer is PA resin (polyamide material). These materials are common insulating materials, and they are adopted because of their good insulating properties, heat resistance and chemical corrosion resistance in electronic equipment. In addition, the three layers of material of this wire are evenly covered on the surface of the conductor to ensure the stability and reliability of the circuit.
