Maintenance pipe for overhead wire

Abstract

The invention relates to a maintenance pipe for an overhead wire. The maintenance pipe for the overhead wire covers the outer side of the overhead wire. The maintenance pipe is characterized by comprising an insulated protective pipe body and a composite protective layer, wherein the insulated protective pipe body is wound around the outer side of the overhead wire, and adhesive is arranged between the insulated protective pipe body and the overhead wire; the composite protective layer covers the outer side of the insulated protective pipe body. The maintenance pipe for the overhead wire can effectively avoid the conflict between a tree and the wire and between the wire and a road, prevent or reduce faults, reduce the production cost for a power supply department, relieve the labor intensity of circuit operation personnel and improve power supply reliability. The wear resistance of the overhead wire can be improved, and the overhead wire has good anti-aging performance; the maintenance pipe is small in unit weight and small in section and has little influence on the sag of the wire; during wire operation, the maintenance pipe can be installed in a electrified mode; and the safety coefficient is increased by the adoption of the maintenance pipe.

Description

technical field [0001] The invention relates to a wire protection and maintenance device, in particular to a maintenance pipe for overhead wires. Background technique [0002] With the rapid development of the distribution network, the power supply channel is covered by trees, severe corrosion, external force damage and many other factors. In order to solve this problem, overhead insulated wires are used for power transmission. Some of the problems encountered, the price is much cheaper than cable transmission, so it is widely used in the distribution network. [0003] However, due to the complex geographical environment of power distribution in urban areas, short-circuit grounding and accidental tripping often occur, resulting in reduced reliability of power supply; Vulnerable to external damage; 3. After use, due to long-term exposure to sunlight, rain, and lightning, cracks or peeling may occur, affecting its mechanical and insulating properties. Therefore, improvements...
