Abstract

The invention discloses a peroxide crosslinked semi-conductive shielding material for crosslinked cable conductors. The peroxide crosslinked semi-conductive shielding material for crosslinked cable conductors comprises the following raw materials in parts by weight: 50-60 parts of ethylene-vinyl acetate copolymer, 20-30 parts of ethylene propylene diene monomer, 30-40 parts of conductive carbon black, 1-3 parts of a crosslinker, 12-15 parts of dioctyl terephthalate, 4-6 parts of diformyl peroxide, 10-20 parts of a plasticizer, 1-5 parts of a flame retardant, 5-10 parts of an antioxidant and 2-10 parts of a stabilizer. The semi-conductive shielding material for cables has good tensile strength and tear resistance by using the ethylene-vinyl acetate copolymer as a main raw material; by adding the peroxide crosslinker, the scorch phenomenon of cables during use is reduced, and the safety and the reliability are improved.

Description

technical field [0001] The invention belongs to the field of cable production materials, in particular to a peroxide crosslinked semiconductive shielding material for crosslinked cable conductors. Background technique [0002] High-voltage DC cable lines are more and more widely used because of their large transmission capacity, low cost, low loss, high reliability, and long life. With the rapid development of electrical engineering and electronic technology, flexible conductive polymers have broad application prospects. In certain applications, multifunctional polymer-based composites with high dielectric constant and high conductivity are attracting more and more attention. Among them, polyethylene (PE) is one of the best insulating materials in the field of HVDC power transmission and distribution. [0003] The traditional cross-linkable semi-conductive inner shielding cable material used for high-voltage XLPE cables can no longer meet the quality and performance requir...
