6).Phase No.: single phase or three phases
7).The Highest Temperature Rise of Windings: 100K
8).Insulation Class: F
9).Cooling Mode: AN or FN
10).Enclosure Protection: IP00, IP20 or custom specified
11).Connection Symbol: Yyn0, Dyn11or II0 or custom specified
12).HV Tapping Range (%): ±5 or ±2×2.5


3. Main Features

1).Low loss, low noise, high operation efficiency
2).High ability of protection against short circuit
3).High mechanical strength
4).Pre-galvanized steel frame, flame-resistant, against corrosion
5).With outstanding fire-proof capability: the epoxy resin is difficult to flame and self-extinguished. So it won’t lead to the second disasters, such as an explosion.
6).Cast epoxy resin with high dielectric strength 18~22kV/mm in vacuum process
7).Superior in environmental performance: the epoxy resin is very stable, moisture-proof and dust-proof. It enables dry-type power transformers to run with high reliability under abominable environment.

8) With theimpeccable temperature control and indicating system, dry-type power transformers can be maintenance free. And this offers a great reduction of operation cost.
9).With small volume, light and convenient for installation and alignment
10).No need of a separated room



4. Materials

1).Insulation Material: epoxy resin
2).Winding Material: Aluminum wire or high quality enameled copper wire (foil winding is available for power transformer)
3).Core: core lamination, low loss, cold rolled grain oriented silicon steel

4.This products is especially suitable to be mounted in the movable or firm switch cabinet, whose width is 650-1200mm. SC10-6(10) (IV) is small,fire-proof and wet-proof.

5.The highest temperature rise of the products’ windings is 100K, their insulation class is F class, and their cooling mode is AN.

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.

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.
