Description
Technical Field
[0001] The utility model relates to the technical field of cable anti-corrosion, in particular to an anti-corrosion sheath for a cable of a power line. Background Art
[0002] The wire sheath is a protective sheath used for pole wires, usually located at the bottom of the wire. Since the wire is made up of multiple strands of steel wire, the contact part is not tight enough and there is a certain gap. Rainwater can easily enter the protective sheath along the wire. This may cause the air inside the sheath to be humid and difficult to dry for a long time, causing the wire to rust and shortening its service life.
[0003] The existing wire pulling sheaths are mostly used in the unobstructed outside world and exposed to the air. Most of the wire pulling sheaths are a PVC pipe sleeve installed on the pole wire, which can be moved at will to protect the wire. The wire pulling sheath is usually installed on the pole wire before the wire is embedded. However, after long-term use, the wire pulling sheath is seriously damaged by wind and sun, and the pole wire cannot be disassembled when powered on, making the replacement of the wire pulling sheath more cumbersome. Failure to replace the sheath will expose the bottom end of the pole wire to the air, causing the pole wire to rust and thus increase the probability of breakage, thereby causing damage to the pole. Utility Model Content
[0004] The utility model aims to solve the problem that after long-term use, the wire sheath is seriously damaged by wind and sun, and the pole wire cannot be disassembled again when the pole wire is energized, which makes the replacement of the wire sheath more cumbersome. If the sheath is not replaced, the bottom end of the pole wire will be exposed to the air, causing the pole wire to rust and thus increase the probability of breakage, thereby causing great damage to the pole. The utility model proposes an anti-rust sheath for power line wire.
