Description

technical field

[0001] The invention relates to a cable branch box, in particular to a gas fully insulated and fully sealed high-voltage cable branch box. Background technique

[0002] The cable branch box is only used as a cable branch. The main function of the cable branch box is to branch or transfer cables. It mainly plays the role of cable branching and cable switching. When the distribution of large independent loads is relatively concentrated, the cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each channel.

[0003] The high-voltage cable branch box in the prior art generally uses a double-way bushing to connect the front connector of the incoming cable and the multi-channel outgoing cable connector. The power failure of the switchgear increases the difficulty of the work, and the work efficiency is low. At the same time, the common cable branch boxes on the market cannot achieve full gas insulat...
