The 10 kV distribution cable line is very close to the ground, and the line is almost insulated to the end. The contact equipment is designed with “five preventions”, so the commonly used live working technology cannot be applied. This article introduces a kind of node cabinet equipment, which is characterized by adopting a single-sided cabinet with double switch structure, and it has one more branch circuit than ordinary single-circuit high-voltage switchgear. Having it installed in the line and its branch line as a permanent controllable power connection point, it can be used with bypass cables, medium voltage generator cars, mobile transformer cars and other equipment for non-stop operation.
