High Thermal Class Motor Winding Awg 14 Enameled Copper Wire is a new type of electromagnetic wire that uses copper as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent conductivity of copper and the light weight of aluminum. Copper enameled wire can be used for signal transmission, but it is prone to problems when used for power transmission, and the life of its products will be greatly reduced. In fact, in the use of copper enameled wire, pay attention to the oxidation protection of the cut surface of the lower enameled wire to ensure the effective combination of copper and aluminum, which can be used for a long time.
