Steel wire armored power cable

Abstract

The invention discloses a steel wire armored power cable, and the cable comprises a filling layer; wire cores are arranged in the filling layer, an insulating layer is arranged outside the filling layer, a flame-retardant layer is arranged outside the insulating layer, a waterproof layer is arranged outside the flame-retardant layer, an insect repelling layer is arranged outside the waterproof layer, and an armored layer is arranged between the insect repelling layer and the waterproof layer; a plurality of insect repelling cavities are formed in the insect repelling layer, insect repelling pills are arranged in the insect repelling cavities, a plurality of first through holes are formed in the tops of the insect repelling cavities, a sliding groove is formed in the middles of the first through holes, and a sealing plate is slidably connected to the inner wall of the sliding groove. According to the invention, when the cable is used for transmission, the gas of the insect expelling pills in the insect expelling cavity can be diffused to the outside of the cable, gradually permeate into soil and expel small animals such as insects and ants, and when the cable does not work, the insect expelling cavity can be sealed, so that the smell of the insect expelling pills is not diffused, the service life of the insect expelling pills is prolonged, and the effect of protecting the cable body is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of armored cables, in particular to a steel wire armored power cable. Background technique [0002] Armored cables are made of different material conductors packed in metal sleeves with insulating materials and processed into a bendable solid assembly. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads. They are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments. are armored thermocouples. [0003] At present, in order to save space, the armored power cables are buried underground, but the armored power cables buried underground are easy to be eaten by termites, mice and other animals. If it is not done well, it will cause termites, mice and other animals to damage the insulation layer and protective layer of the cable, ...

Problems solved by technology

[0003] At present, in order to save space, the armored power cables are buried underground, but the armored power cables buried underground are easy to be eaten by termites, mice and other animals. If it is not done well, it will cause termites, mice and other animals to damage the insulation layer and protective layer of the cable, or the entire cable will break, resulting in the loss of the power transmission function of the cable.
