Wire insulation refers to the uniform and sealed wrapping of a layer of non-conductive materials, such as plastic, silicone rubber, resin, PVC, etc., around the periphery of a wire to form an insulation layer, preventing the conductive body from coming into contact with the outside world and causing accidents such as leakage and electric shock. The wire is called an insulated wire. There are many types of it, such as rubber insulated wires suitable for fixed installation of electrical equipment and lighting devices with AC voltage below 500V. The long-term allowable working temperature of wires should not exceed 65 ℃. PVC insulated wires are suitable for fixed laying of power devices with AC rated voltage of 450/750V and below
