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 Features

The air insulation distance is large enough to avoid the possibility of accidents between phases.

The protection level of the shell is IP4X, which effectively prevents the human body and external solid objects from approaching live parts.

Protect personal safety and ensure reliable operation of equipment.

Key components of high-current equipment are made of non-magnetic materials to solve the temperature rise problem of high current.

Conditions of useService conditions

Ambient temperature: the highest temperature: +40℃, the lowest temperature: -15℃.

Environmental humidity Daily average relative humidity: ≤95%; Monthly average relative humidity: ≤90%

Altitude: no more than 1000m.
