Waterproof power cable

Abstract

The invention discloses a waterproof power cable, comprising a conductor and a sheath layer covering the outer side of the conductor, where the sheath layer is prepared from the following raw materials in parts by weight: 25-35 parts of chlorinated rubber, 30-42 parts of ethylene propylene diene monomer, 0.5-1.2 parts of sulphur, 0.1-0.6 part of stearic acid, 0.1-0.6 part of triallyl isocyanurate, 1-3 parts of magnesium oxide, 15-25 parts of modified kaolin, 20-28 parts of sepiolite powder, 40-60 parts of white carbon black, 2-8 parts of ground calcium carbonate, 11-15 parts of halloysite, 4-9 parts of glass fibre, 0.5-1.5 parts of chlorinated paraffin, 1-2 parts of pentaerythritol ester, 0.2-0.8 part of an anti-aging agent RD and 1-2 parts of an anti-aging agent D. The waterproof power cable provided by the invention has excellent water resistance, good sterilization performance and antibacterial activity and excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a waterproof power cable. 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 been developed by leaps and bounds. Power cables are often used in a humid working environment. In such an environment, water branches often grow out of 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 loss of the cable is...

Problems solved by technology

Power cables are often used in a humid working environment. In such an environment, water branches often grow out of 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 loss of the cable is reduced, the insulation resistance and breakdown voltage are reduced, and the service life of the cable is shortened. The greater the humidity, the more water branches will be generated, and in the long-distance transmission, the cable length is longer. location found
