Description
技术领域 technical field

背景技术 Background technique

Its disadvantages are: in order to prevent arc discharge and reduce the volume of the cable branch box, the box is filled with SF 6 gas, and SF 6 gas will produce harmful substances to the human body, and it will affect the air pressure in the box when used in high temperature areas. The gas will be liquefied when used in low-temperature areas. After the cable branch box is used, the airtightness needs to be checked irregularly, and the maintenance cost in the later period is high. The wiring in the cable branch box is complicated, which increases the production cost.
