Product Overview
Our fully self-protected distribution transformers are primarily used
to supply power to lighting systems, agricultural production and
industrial facilities in rural areas, remote regions and scattered
villages. They are also suitable for pole-mounted distribution lines in
railway and urban power grids. These transformers are equipped with
HJ International CSP circuit breakers and load indicator lights.
