Problems solved by technology

[0002] Before the implementation of international standards, hemp rope was used to fill cross-linked cables, and then polypropylene was used to tear the film rope. However, due to its loose texture and lack of rigidity, it is not as strong as hemp rope and has good roundness. Plastic filling strips, but the use effect is not good, the cable is hexagonal, the appearance quality is not good, and the head cover is not sealed, easy to enter water, which is strongly reflected by users

Abstract

The invention discloses an environment-friendly 35KV special high-voltage cable filling strip and a preparation method thereof. The filling strip is composed of, by weight, 45-50 parts of low-density polyethylene, 40-45 parts of linear low-density polyethylene, 20-25 parts of metallocene linear low-density polyethylene resin, 38-42 parts of high-pressure polyethylene, 5-7 parts of modified white carbon black, 0.5-0.7 parts of a rheological agent PPA, 0.9-1.1 parts of stearic acid, 0.2-0.4 parts of an antioxidant B225, 2.8-3.2 parts of a PE toughening agent, 0.9-1.1 parts of asphalt, and 0.4-0.6 parts of an AC foaming agent. The 35KV special high-voltage cable filling strip provided by the invention has the advantages of good plasticization, uniform extrusion, no impurity, no oil stain, no water stain, smooth surface, uniform color, reduced cost, low density, reduced cable outer diameter, improved roundness, pressure resistance, temperature resistance, light specific weight, high tensile strength, and the like.

Description

technical field [0001] The invention relates to an environment-friendly 35KV special high-voltage cable filler strip and a preparation method thereof, belonging to the technical field of cables. Background technique [0002] Before the implementation of international standards, hemp rope was used to fill cross-linked cables, and then polypropylene was used to tear the film rope. However, due to its loose texture and lack of rigidity, it is not as strong as hemp rope and has good roundness. Plastic filling strips, but the use effect is not good, the cable is hexagonal, the appearance quality is not good, and the head cover is not sealed, easy to enter water, which is strongly reflected by users. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly 35KV special high-voltage cable filler strip and a preparation method thereof. [0004] The present invention adopts following technical scheme: [0005] Environmentally fr...
