Description

Wire protecting strip

Technical Field

The application relates to the technical field of wire protecting strips, in particular to a wire protecting strip.

Background

In order to prevent the suspension point of the overhead power line from being damaged due to vibration, the wire protecting strip is additionally arranged at the wire clamp of the line conductor, so that the rigidity near the wire clamp is enhanced, the bending, extrusion stress and abrasion of the conductor due to vibration are inhibited, and the vibration resistance of the conductor is improved. However, the existing guard bar structure is not reasonable in design, and the problem of point discharge is easily caused.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned deficiencies of the prior art, the present application provides a wire protecting strip with the advantage of avoiding point discharge.

The technical purpose of the application is realized by the following technical scheme: a wire protecting strip comprises a wire protecting strip body used for coating a cable, wherein the wire protecting strip body is made of aluminum alloy, and the end part of the wire protecting strip body is in flat smooth transition along the length direction of the wire protecting strip body; the line protecting strip body is further coated with a silica gel layer, an insulating layer, a wear-resistant layer and a mica tape layer from inside to outside.

Preferably, the insulating layer is made of polyvinyl chloride material.

Preferably, the wear-resistant layer is made of a polyurethane material.

Preferably, a sheath is further sleeved outside the mica tape layer.

To sum up, the beneficial effect that this application has: set up to the platykurtic through protecting the line strip tip, and along the length direction smooth transition of protecting the line strip body, can avoid the production of point discharge phenomenon, and set up the silica gel layer, make the protecting the line strip have certain bending capability, the insulating layer, make the protecting the line strip have better insulating ability, avoid appearing the phenomenon that voltage was put outward, wearing layer through setting up, make the protecting the line strip have certain wear resistance, the quality of protecting the line strip is greatly improved, the mica tape layer can improve the high temperature resistance ability of protecting the line strip.
