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.
