Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a closed insulated busbar. Background Technology

[0002] High-voltage busbar trunking is a closed metal device consisting of copper or aluminum busbar columns encased in an outer shell. It is used to distribute a large amount of power to various components of a distributed system. To ensure the safety of high-voltage busbar trunking, insulating materials are generally installed inside the outer shell, and the trunking is installed in high-altitude areas such as indoor rooftops to avoid contact with pedestrians. This method ensures the safety of surrounding pedestrians.

[0003] After a period of use, the busbar trunking needs to be inspected to prevent malfunctions that could affect its operation. However, since the busbar trunking is installed in an indoor high-altitude area, maintenance requires the use of ladders for high-altitude operations. During maintenance, a large number of disassembly tools need to be carried, increasing the safety risks. Therefore, a closed, insulated busbar trunking system is needed to solve the above problems.
