Detail

Iron core

The iron core is made of imported cold-rolled silicon steel sheets with inclined joint structure, core limbs are bound by
unidirectional wattless tape of class F.Surface of iron core is encapsulated with epoxy resin, which reduces the no-load o=current
and core noise.
Clamps and fasteners have gone through special surface treatment that further improves the product appearance quality.

Winding

High-voltage winding applies vacuum casting of stuffing epoxy resin which sharply reduces partial discharge and enhances the
electric of coils. The inside and outside of the winding is bulk up with glass fiber grid overlay which strengthens the mechanical
robustness of coils and product's short-circuit withstand capability, the coil will not split forever.

Low-voltage winding applies foil structure which solves the problem of axial? angle? when? winds and make the ampere-turn of
winding distribute evenly. Meanwhile, the coils adopt axial cooling duct to improve the heat dissipation. Between the layers of
winding, it applies DMD resin preliminary immersed cloth and makes it whole solidification forming,

Manufacturing process

The coils are wound on high precision winding machine.We adopt foil type winding structure for low-voltage winding. Transformers
of larger capacity are equipped with ventisting duct, it is vacuum drying, casting and solidification folkwed the winding, all
processes are operated accord with the technological requirements under strict monitoring and may be regulated as appropriate. The
precise manufacturing of casting ensures no bubble or cavity in coil, and gets high quality operation of transformer finally.

Temperature control and air cooling systems

It adopts crossflow top-blow fan which is featured with low noise, high wind pressure and good looking, etc,. it improve the
safety and reliability if the operation of transformer.

Protective shell and outgoing bus

The shell makes further protection for the transformer. For user's option, the grade of protection has IP20, IP23, ect,. Shell
material include cold-rolled steal sheets, stainless steal sheets and so on for option. The low-voltage outgoing adopts standard
outgoing bus, side outgoing and top outgoing are available, or design special outgoing modes for users.
