Introduction

As a new type of power distribution equipment, American type of cubicle transformer substation is to place high-voltage load-breaking switch and high-voltage fuse in transformer oil for insulation and cooling. As an important power supply unit in cabling power distribution network, and a complete pre-assembled product integrating high-voltage control, protection and transformation and power distribution equipment, the product especially applies to load center of urban power grid, reduction of loss and enhancement of power supply quality. The series of products have been widely used in power distribution locations such as residential district, public location and industrial and mining enterprises nationwide.
