Abstract
The utility model relates to the field of power transmission equipment, and particularly to a fireproof wire. The fireproof wire comprises a wire body, conductive wires, a ground wire, a fireproof layer, an oxidation resistance layer, an insulation fireproof layer and an insulation jacket. Two conductive wires and one ground wire are arranged within the wire body; the fireproof layer the wraps the outside of the conductive wires; the oxidation resistance layer wraps the outside of the ground wire; the insulation fireproof layer wraps around the conductive wires and the ground wire; the insulation jacket sleeves the insulation fireproof layer; and an aluminum oxide layer is arranged between the insulation fireproof layer and the insulation jacket. The fireproof wire is simple, compact and reasonable in structure, and has good fire resistance, a good shielding property, good insulation performance and good corona resistance. Furthermore, the fireproof wire has high heat tolerance index, prolongs service life of the wire, dramatically improves operation reliability of the wire and is easy for popularization.
