Product Description
Combined substation (hereinafter referred to as American box-type substation) puts the transformer body, high-voltage load switch, protection fuse and other equipment in the same sealed oil tank, so it is smaller in size. American box-type substation can be used both outdoors and indoors , widely used in industrial parks, residential areas, commercial centers, high-rise buildings and other places.

Product FeaturesProduct Features
It can cut off the load current and perform full-range current protection. There are two power supply modes, ring network and terminal, to choose from. It has the basic functions of a substation.
Low investment, less floor space, simple installation, and quick results; the product requires less capital investment and floor space than European transformers or power distribution rooms. During installation, you only need to tighten four installation bolts and connect the incoming and outgoing cables. Can.
It has good safety and adopts a fully enclosed design. The product shell is directly grounded and there is no conductive part on the outer surface to ensure personal safety. It adopts an anti-theft structure design to prevent malicious disassembly.
It has simple maintenance, high protection level and good weather resistance; it is suitable for various places with harsh climates.
