Pad mounted Transformers

The ZGS11 Series Pad mounted Transformers are widely used in high-rise buildings, hotels, villas safe and reliable.

The ZGS11 Series Pad mounted Transformers are in accordance with the national standard JB/T10217-2000 Padmounted Transformer and enterprise standard Q/321284JCA39-2003 Padmounted Transformer.

The ZGS11 Series Padmounted Transformers are widely used in high-rise buildings, hotels, villas, residence communities, parks, and street lamps.

Structural features

The core uses high-quality cold-rolled grain orientation silicon steel sheet. The no-load loss of the product is 30% lower than the 9 series. The transformer chamber, high-voltage chamber, and low-voltage chamber are in optimized combination. They are pre-formed in the factory. Therefore, the structure of the product is simplified. The size is about 1/3 of that in China with the same capacity. The transformer is suitable for residence communities, commercial entertainment center, and street lamps in cities. It will be useful for saving the land resource. Products are hermetically-sealed and insulated without any exposed electrified component and are safe and reliable. Products can be used on terminals and looped network. The transformation is convenient. Cases are of corrosion protection design. Special spray painting treatment is used. Products are suitable for using under severe environment.
