Cross linked polyethylene insulated copper strip armored power cable preventing termites and resisting ultraviolet light

Abstract

The invention discloses a cross linked polyethylene insulated copper strip armored power cable preventing termites and resisting ultraviolet light. The power cable sequentially comprises an insulated cable core, a semiconductive buffer layer, a metal shielding layer, a high-inflaming-retarding enhancement layer, a lining layer, a metal armored layer and an outer protection sleeve from the inner layer to the outer layer. The semiconductive buffer layer is composed of semiconductor non-woven fabric, the metal shielding layer is composed of copper wires evenly arranged in the peripheral direction and copper strips inversely tied on the outer surface of the copper wires, the lining layer is composed of halogen-free low-smoke high-inflaming-retarding polyolefin outer protection sleeve materials, the metal armored layer is composed of a brass strip armored cable, and the outer protection sleeve is composed of low-smoke halogen-free inflaming-retarding outer protection sleeve materials. Through the mode, the power cable has the special performance of being low in smoke and free of halogen, retarding inflaming, being waterproof and ratproof, preventing insect biting and preventing the ultraviolet light, the service life of the cable is guaranteed, the safe reliability of electric power transmission is improved, and hazards caused by electricity utilization faults are avoided.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a cross-linked polyethylene insulated copper tape armored anti-termite and anti-ultraviolet power cable. Background technique [0002] With the improvement of people's living conditions, people pay more and more attention to health, safety and environmental protection. However, for traditional PVC (polyvinyl chloride) cables, when a fire occurs, the PVC mixture is easy to decompose after being heated, releasing a large amount of highly toxic and corrosive HCL (hydrogen chloride) gas, and producing a large amount of highly toxic smoke, causing major fires. Loss of life and property, and bring great difficulties to the rescue work. In order to avoid and reduce fire and secondary damage caused by fire, a halogen-free low-smoke flame-retardant cable has been developed. However, ordinary halogen-free low-smoke flame-retardant cables are also prone to problems such as outer sheath crackin...

AI Technical Summary

Problems solved by technology

However, ordinary halogen-free low-smoke flame-retardant cables are also prone to problems such as outer sheath cracking and damage by insects and rats, which greatly shorten the life of the cable, cause power failures, and cause damage to the national economy.

The main reason for the cracking of the outer sheath is that more flame retardant fillers are added to the material itself, which leads to a decrease in its mechanical properties. In addition, the outer sheath does not have anti-ultraviolet and anti-sunshine performance, and long-term operation may easily cause the outer sheath to crack.
