Product description

Model meaning


Overview & features

It can be widely used in locations where have strict fireproof requirements, such as underground mines, oil fields, metros, power plants, schools, hospitals, commercial centers, high-rise buildings and all indoor systems.

Iron

◎ The iron core is made of imported cold-rolled silicon steel sheets with inclined joint structure, core limbs are bound by unidirectional weftless tape of class F. 

◎ Surface of iron core is encapsulated with epoxy resin, which reduces the no-load noise, no-load current and core noise. 

◎ Clamps and fasteners have gone through special surface treatment that further improves the product appearance quality. 

High-voltage winding 

High-voltage winding applies vacuum casting of stuffing epoxy resin which sharply reduces partial discharge capacity and enhances the electric strength of coils. The inside and outside of the winding is buildup 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 

Low-voltage winding applies foil structure which solves the problem of axial helix 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 epoxy 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 windings. Transformers of larger capacity are equipped with ventilating duct. It is vacuum drying, casting and solidification followed 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 improves the safety and reliability of 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, etc. Shell materials include cold-rolled steel sheets, stainless steel 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 user
