Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, in particular to a wear-resistant electric wire. Background Art

[0002] Wires refer to conductors that transmit electrical energy, which are divided into bare wires, electromagnetic wires and insulated wires. Bare wires have no insulation layer, including copper and aluminum flat wires, overhead stranded wires and various profiles. They are mainly used for outdoor overhead and indoor busbars and switch boxes. Electromagnetic wires are insulated wires that generate magnetic fields or induce currents in magnetic fields after being energized. They are mainly used for motor and transformer windings and other related electromagnetic equipment. The 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, etc. Different insulation materials can be used to obtain different characteristics.

A second wear-resistant layer is installed to protect the outer ring of the electric wire and improve the wear resistance of the overall electric wire. However, in the prior art of this device, the electric wire is exposed to the outside and has no protective mechanism, which makes it easy for the overall electric wire to be affected by the external environment, seriously affecting the service life of the electric wire.
