There are many matters needing attention in the operation and maintenance of power cables, especially in the line maintenance, which mainly includes three aspects: load monitoring, cable sheath corrosion monitoring and insulation monitoring, so as to keep the cable equipment in good condition and prevent cable accidents.
The operation of power cable line is extremely important in the whole power production link, because the operation safety of cable line is directly related to the production safety of enterprises and the safety of people’s lives and property. Therefore, it is very important to understand the operation and maintenance of power cables and lines.
In the power industry, the so-called cable line actually refers to the line for cable transmission of electric energy. Generally, it consists of cable, cable intermediate joint, electric line end, etc., including laying related projects, such as cable trench, pipe row, shaft, tunnel, etc. the cable line will be adjusted according to local conditions according to different geographical environment and different construction requirements.
The power protection bushing of GWH has excellent properties of softness, bending resistance, cold resistance, heat resistance, flame retardant, waterproof and low thermal conductivity. It can reduce loss in substation cable protection. Because of its convenient construction, neat and beautiful appearance and no pollution, it is a high-quality new temperature resistant protective material.
