Product Introduction

ZGS11-12/0.4 type American box transformer is a prefabricated substation equipment, which designs the transformer body, high-voltage load switch, protective fuse and other equipment uniformly and places them in the same sealed oil tank. This device is suitable for 12kV ring network power supply, dual power supply or terminal power supply systems, and is widely used in urban and rural distribution networks, urban residential areas, commercial centers, airports, stations, schools, hospitals and other places.

Application

: Urban high-rise buildings, residential communities, and commercial centers.

: Industrial parks, schools, hospitals, airports, and train stations.

: Temporary construction electricity and rural power grid renovation.

: Fully sealed and insulated design
The equipment adopts a fully sealed structure, without the need for insulation distance, ensuring personal safety.

: Compact structure and small volume
The volume is only 1/3 to 1/5 of the same capacity European box transformer, with a small footprint and easy installation and maintenance.

: Low loss, low noise
Adopting transformers with low loss, low temperature rise, and low noise, fully sealed and maintenance free.

: High reliability
Equipped with comprehensive protection functions such as oil temperature gauge, oil level gauge, pressure relief valve, etc., to ensure the safe operation of the equipment.
