High-strength glass fiber woven and wound pultrusion cable protection bushing

Abstract

The invention discloses a high-strength glass fiber woven and wound pultrusion cable protection bushing, which comprises a bushing main body, wherein thebushing main body comprises an upper bushingand a lower bushing,two sides of the upper bushingare fixedly provided with fixed clamping hooks, two sides of the lower bushing are fixedly provided with clamping strips, the outer surface of the bushingmain body is provided with an outer shielding layer, a middle glass fiber woven and wound pultrusion layer is fixedly arranged on the inner side of the outer shielding layer, an inner woven layer is fixedly arranged on the inner side of the middle glass fiber woven and wound pultrusion layer, an inner supporting ring is fixedly arranged in the center of the interior of the bushing mainbody, and a supporting plate is fixedly arranged between the outer surface of the inner supporting ring and the inner wall of the inner woven layer. According to the invention, the working efficiency and the product quality are effectively improved, and the cable has the advantages of high temperature resistance, difficulty in aging, strong and weak current resistance, convenience in installation, no damage to the cable, high practicability and suitability for wide popularization.

Description

technical field [0001] The invention belongs to the technical field of cable protection sleeves, in particular to a high-strength glass fiber braided and pultruded cable protection sleeve. Background technique [0002] Cable protection sleeve is a new type of sleeve material popularized and used in electric power engineering. With the rapid development of power cable buried laying projects, higher requirements are put forward for cable casings. Cable protection casings are made of polyethylene PE and high-quality steel pipes, which are pre-treated by sandblasting and shot blasting, dipped or coated, and heated. Made by curing process. However, the existing cable protection sleeve is a hollow tube structure, and the cable is loaded and unloaded by plugging and pulling. The friction between the cable and the sleeve will easily cause the cable insulation layer to wear out, and the loading and unloading operation is inconvenient. They are not resistant to high temperature, and...

Problems solved by technology

However, the existing cable protection sleeve is a hollow tube structure, and the cable is loaded and unloaded by plugging and pulling. The friction between the cable and the sleeve will easily cause the cable insulation layer to wear out, and the loading and unloading operation is inconvenient. They are not resistant to high temperature, and are easy to age, have low mechanical strength, and are not resistant to strong and weak electricity.
