ABOUT PRODUCTS
DRY TRANSFORMERS
Our dry transformers use insulating paper with
strong heat and moisture resistance,
and are impregnated with high-quality varnish to
reduce the risk of fire. Maintenance and
inspection are simple and easy to handle.
We produce and supply a variety of models,
from small for operation to large capacity.

SCOTT TRANSFORMER
◈ Purpose of use
It is a transformer (Scott Connection Transformer)
used by converting three-phase power into a single-
phase large capacity load. It is a special transformer
used to reduce three-phase imbalance that occurs
when using a single-phase load.

single-phase large capacity loads in three-phase power
sources such as AC electric railways, electric furnaces,
charging storage devices, and ESS.
◈ Features
1. As a basic transformer, it has good electrical
characteristics and excellent dielectric strength.
2. If both sets of single-phase power sources are
equal, the three-phase load is balanced on the three-
phase power side.
