Power cable with excellent mechanical performances

Abstract

The invention discloses a power cable with excellent mechanical performances, the power cable includes a conductor and a sheath layer coating the outer side of the conductor; the sheath layer comprises the following raw materials by weight: 38-48 parts of ethylene-vinyl acetate polymer, 30-40 parts of chlorinated polyethylene, 1.5-2.5 parts of tricresyl phosphate, 1-2 parts of microcrystalline wax, 24-32 parts of diatomite, 6-10 parts of sepiolite powder, 45-65 parts of white carbon black, 13-17 parts of glass bead, 4-10 parts of wollastonite, 20-30 parts of modified bentonite, 3-5 parts of zinc oxide, 0.4-0.8 part of Triallyl isocyanurate, 0.4-1 part of peroxide cyclohexanone, 0.8-1.6 parts of benzoyl peroxide, 0.5-1 part of antioxidant AW and 1.5-2.5 parts of antioxidant NBC. The power cable with excellent mechanical performances has excellent waterproof property, excellent bactericidal and bacteriostatic performances and excellent mechanical performances.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a power cable with excellent mechanical properties. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating sheath. Most of them are erected in the air or installed underground or underwater for telecommunications or power transmission. [0003] With the development of our country's economy, our country's electric power and communication equipment have developed by leaps and bounds. Cables are often used in a humid working environment. In such an environment, water branches often grow on the cable, which is easy to breed bacteria and corrode the sheath layer. In addition, too much water branches will cause the cable to be interrupted during operation, increasing the The cable...

Problems solved by technology

Cables are often used in a humid working environment. In such an environment, water branches often grow on the cable, which is easy to breed bacteria and corrode the sheath layer. In addition, too much water branches will cause the cable to be interrupted during operation, increasing the The cable loss, insulation resistance and breakdown voltage decrease, which shortens the service life of the cable. The greater the humidity, the more water branches will be generated. In addition, in long-distance transmission, the length of the cable is longer. If there is a leakage in the middle, it cannot be found in time. Positioned
