Abstract

The invention discloses a wear-resistant modified polystyrene cable, which comprises: at least one conductor core, an insulating layer wrapped around the conductor core, a shielding layer wrapped around the insulating layer, a wrapping The sheath layer wrapped around the shielding layer; the sheath layer includes an inner sheath, an inner liner, an armor layer and an outer layer; the inner sheath and the outer layer are made of modified polystyrene Prepared from ethylene material; the modified polystyrene material includes the following raw materials in parts by weight: 8-15 parts of ceramic particles, 10-15 parts of modifier, 20-30 parts of polyethylene, 35 parts ‑55 parts of polystyrene, 0.3‑0.8 parts of coupling agent, 0.3‑0.5 parts of crosslinking agent; the cable uses the modified polystyrene material with excellent wear resistance as the cable sheath The outer layer in the jacket improves the wear resistance of the polystyrene cable, so that the polystyrene cable can be used for a long time in a high-abrasion environment.

Description

Technical field [0001] The invention relates to the field of cables, in particular to a wear-resistant modified polystyrene cable. Background technique [0002] A cable is a wire formed by twisting one or more wires into a conductor core, and then applying a corresponding insulation layer on the conductor, and a sealed sheath on the outer cover. It is mainly composed of a core, an insulation layer and a shielding layer. And the sheath layer. The cable has the advantages of occupying the ground and less space; the power supply is safe and reliable, and the possibility of electric shock is small; it is beneficial to improve the power factor of the power system; the operation and maintenance are simple and convenient; it is beneficial to beautify the city, has many advantages such as confidentiality, and is widely used in life And all areas of production. The performance of the cable jacket layer is one of the main factors that determine the cable use environment. At the same time...
