Some wires are prone to deformation and cracks on the surface. In case of water leakage in a certain area, it can lead to electrical damage, short circuits, and even cause fires and casualties. So it is necessary to use wires with a hard outer skin and good waterproof performance.

Electric wires refer to wires that transmit electrical energy. Divided into bare wire, electromagnetic wire, and insulated wire. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires, and various profiles. It is mainly used for outdoor overhead and indoor busbars and switch boxes. Electromagnetic wire is an insulated wire that generates a magnetic field after being energized or induces current in the magnetic field. It is mainly used for winding motors and transformers, as well as other related electromagnetic equipment. Its conductor is mainly copper wire, which should have a thin insulation layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance, and other properties. Choosing different insulation materials can achieve different characteristics.
