Abstract

The invention relates to a multifunctional multilayer insulated wire, which comprises a copper lead, a bonding layer, an insulating layer, a flame-retardant layer and a protecting layer, wherein the bonding layer is coated outside the copper lead, the insulating layer is covered outside the bonding layer, the flame-retardant layer is covered outside the insulating layer, and the protecting layer is covered outside the flame-retardant layer. The insulated wire can be widely used in the high-frequency wires of power supplies and transformers.

Description

technical field [0001] The patent of the present invention relates to the field of insulated wires, especially multi-functional multilayer insulated wires, which have good high temperature resistance, high pressure resistance and wear resistance. Background technique [0002] At present, the high-frequency wires of power supplies and transformers used in the market are all single-layer insulated wires, and the outer coating of this type of insulated wires is made of plastic materials, which will cause air bubbles and pinholes during the molding process; At the same time, during the winding process, this type of insulated wire is prone to wear and internal slippage, and is prone to electrical breakdown, making it lose its electrical insulation. Therefore, the market urgently needs multi-functional multi-layer insulated wires with good high pressure resistance, high temperature resistance and wear resistance.
