Low voltage Dry Type Transformer

Epoxy resin cast dry-type transformer is a high-performance dry-type
transformer characterized by superior electrical strength, mechanical
durability, and heat resistance. It is an excellent choice for urban power grid
transformation projects. Manufactured using advanced production and testing
equipment in accordance with stringent technological standards, this Low
voltage Dry Type Transformer offers high reliability and a long service life.
Depending on the application environment, it can be equipped with various
levels of protective shell or without a shell. This makes it suitable for a
wide range of environments including high-rise buildings, commercial centers,
hospitals, airports, subways, tunnels, densely populated residential areas, as
well as special environments such as oil refineries, chemical plants, nuclear
power plants, and nuclear submarines.
Dry Type Electric Transformer Features:
·High voltage winding
High voltage winding is with epoxy resin filled vacuum casting, which greatly
reduces the partial discharge and improves the electrical strength of the
coil. The inner and outer walls of the winding with glass fiber mesh plate
filling, improves the impact toughness of the coil and the ability of
resistance to sudden short circuit of the transformer. The coil is never dry
crack.
·Low voltage winding
The foil structure of the low-voltage winding solves the problem of radial
helix angle when winding with wire, and makes the ampere-turns more balanced.
At the same time, the coil uses radial cooling air pipe, which improves the
heat defeat ability. The winding solid layer uses DMD epoxy resin prepreg , and
the overall is dry solid forming.
·Iron core
The iron core is made of high-quality cold-rolled silicon steel sheet, 45°
full oblique joint structure; The core column is bound with F grade weftless
adhesive tape, and the core surface is wrapped with epoxy resin, which reduces
no-load loss, no-load current and iron core noise. Clamping parts and fasteners
are treated with a unique surface to further improve the appearance quality of
the product.
