Problems solved by technology

[0004] However, cables are generally buried underground. The underground soil contains many bacteria, eggs or insects in the natural environment. Bacteria, eggs or insects will form a certain degree of biological erosion on the surface of the cable. The cable is not subject to mechanical damage, but there will be a certain mechanical gap between its steel strips, steel wires or copper strips. Under the ground, these bacteria, insect eggs or insects are small and can touch the sealing sheath through the mechanical gap. The outer sealing sheath of the cable is damaged, and the inner insulating layer and conductive core are partially exposed, which is easy to cause leakage, and also causes instability of the cable line, and increases the cost of later maintenance and repair. put in

Embodiment 1

[0045] see figure 1 , an underground self-repelling insect cable, comprising a conductive wire core 1, the outer end of the conductive wire core 1 is provided with an insulating layer 2, the outer end of the insulating layer 2 is provided with a sealing sheath 3, and the outer end of the sealing sheath 3 is covered A protective covering layer 4 is provided, and the outer end of the protective covering layer 4 is fixedly connected with a plurality of raised hemispheres 6, and the surface of the raised hemispheres 6 is coated with an insect-proof coating. When the cable is buried underground, the insect-proof coating can effectively prevent bacteria, Insect eggs or insects approach the cable, thereby reducing the impact of bacteria, insect eggs or individual insects on the cable, prolonging the service life of the cable, thereby prolonging the time for maintenance and repair of the cable in the later stage, please refer to image 3 , the raised hemispheres 6 are discontinuously ...

Abstract

The invention discloses a buried self-insect-repelling cable and a burying method thereof, belonging to the field of cables. When a cable is buried underground, an insect expelling layer and a concrete layer are arranged between the cable and the soil to effectively isolate the cable from the soil so as to reduce the contact between the insects in the soil and the cable and reduce the probabilityof the cable generating the biological erosion phenomenon, and when insects in the soil are close to the insect expelling layer, the insects can be intercepted so as to achieve the effect on insect expelling and killing, and a coating wrapping layer and convex hemispheres are arranged at the outer portion of the protection coating layer of the cable to effectively intercept insects passing throughthe insect expelling layer and being in contact with the cable from continuously moving towards the internal portion of the cable, and after the inner filling agent in the convex hemispheres flows out, the effect on insect expelling and killing is further improved so as to reduce the probability of the cable being eroded by organisms and prolong the service life of the cable.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to an underground self-repelling insect cable and an embedding method thereof. Background technique [0002] The cable is mainly composed of the following 4 parts. ① Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be formed by twisting a single wire or multiple wires. ②Insulation layer: The insulation material used for cables should have high insulation resistance, high breakdown electric field strength, low dielectric loss and low dielectric constant. Commonly used insulating materials in cables are oil-impregnated paper, polyvinyl chloride, polyethylene, cross-linked polyethylene, rubber, etc. Cables are often classified by insulating materials, such as oil-impregnated paper insulated cables, PVC cables, XLPE cables, etc. ③ Sealing sheath: protect the...
