Product Description

Dry type transformer

Epoxy Resin cast  Dry-Type Transformer 11KV 33KV 0

SCB Dry Type power distribution transformer


Overview & features


SCB epoxy resin pouring dry-type transformer is manufactured in conformity with IEC60726 standards (applicable International Electrotechnical Commission standards), GB6450 standards and GB/T10228 standards (applicable state standards of the People's Republic of China). Frequency: 50Hz. It can be used for electric transformation and distribution of urban power grids. It is primarily applicable for high-rise buildings, commercial centers, airports, offshore drilling platforms, ships, tunnels, large hydropower stations and railway stations

There is protection shell option, IP grade is IP20,IP30,IP40. the material of the shell is stainless steel,aluminum alloy, aluminium-Zinc alloy coated steel. It is easy for operation,installation and light weight.It won't effect ventilation and heat dissipation, the door can be at both high voltage and low voltage side, or as per your request.


Iron core

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.


SC(B) Series DRY EPOXY RESIN DISTRIBUTION POWER TRANSFORMER is widely applied in hotels, high buildings, business centers, residence community, gymnasium, Petrochemical plant, airport, harbor, metro, mine, drillic.

Product details



Low loss:the product no-load loss is 20% lower than the Sc (B) 11 type product with an  excellent energysaving effect, economic efficient operation and without maintenance.

Low noise:the product noise level is 10-15 db lower than the existing professional standard
 JB/T10088- 2004Sound Level of 6- -220KV Transformer

Low partial discharge:resin mixture adopts foreign leading-edge mixing method and film type
 vacuumdeaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture.

The product  low partial discharge which can be controlled at 5PC. Both high voltage and low voltage coils can bepoured in vacuum pressure so as to enable a encapsulating of resin insulation  and immersion amonglayers and inter-tums. The poured part has a compact solidity staicture with  anti-flaming, anti explosionand environmental protection features. Glass fiber and other raw materials of winding coil have self- extinguishing property and will not  producearc due to short circuit. Resin will not produce harmful gas under high temperature.

SCOPE of application


None of the dry-type transformers we see today are installed in a separate, tightly enclosed room, as in

the oil-immersed type, but only in a relatively dry and clean room. In addition to this, it is also very convenient

to transport or carry, no matter what kind of transport vehicles, trains, cars or other non-motor vehicles can be,

but it is best to keep the car dry, clean and the product itself in good packaging. Practice has proved that really

good products will always be more and more marketable. As dry-type transformers have very good fire-proof

performance and are easy to install and maintain, they are also used more and more widely Especially in the

modern commercial downtown, residential areas, hospitals, airports, stations, subways, theaters, schools,

public places and other places with high requirements on fire protection.
