Insulated wires for electrical, electronic and communications devices supply power to general households and factories, electrical and electronic components in large machinery and communications devices. The wires are made of drawn copper, copper alloys, aluminum, etc., and are used to connect and conduct electricity between 2 points. These wires feature conductors made of copper, etc., covered with an insulator. The wires are classified into insulated wires that transmit high current and those that transmit low current, with insulation material made of vinyl, PVC, polyethylene, etc. Some insulated wires feature fluoropolymer and polyester materials. Some insulated wires also feature a protective coating on top of the insulator.
