Product Description

Dry type transformer

11kv 33kv silicon steel core dry type cast resin transformer 800kva 0

Product introduction
Dry-type transformer has the advantages of large short-circuit resistance, little maintenance work, high operation efficiency, small dimension and low noise, which is commonly used in places with high requirements of fireproof and explosion-proof. This type transformer is widely used in local lighting, high buildings, airports, docks, CNC machinery and others. Its cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). The transformer can operate continuously for a long time under rated capacity under natural air cooling. Output capacity of the transformer can increase by 50% under forced air cooling. It is suitable for intermittent overload operation or emergency overload operation. Due to the load loss and impedance voltage increase significantly when overload, it is not suitable for long time continuous overload operation.
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.

Function Characteristics:

●Flame retardant, non-pollution, it can be installed directly in the load center.
●Maintenance-free, easy to be installed, low operating costs.
●The enclosure can be of Good moisture resistance, transformer can be put into operation without pre-drying under 100% humidity in the normal operation.
●Low loss, light weight and small volume, low noise, good dissipation of heat, it can be 150% rated load operation under forced air cooling conditions.
●Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of
●High reliability. The results of checking for the products that has been put into operation show that the reliability index has reached the international advanced level.


Structural Characteristics:

Cast-foil Coil: Adopting the entire section of copper foil, together with the F-class turn insulation, low voltage winding is wound by the special low-voltage foil winding machine. The foil coil resolves such understanding problems as large short-circuit stress, uneven ampere turn, poor heat dissipation, existing the winding spiral angle as well as unsteady manual welding quality due to low voltage and large current coil winding products. At the same time, the winding end in our company is treated with resin potting, solidification to make shape, moisture-proof and anti-fouling, the lead copper platoon is automatically welded by argon arc welding.

Temperature Control Device: the transformer adopts BWDK series of signal thermometer. The temperature components, are embedded in the upper half of the low-voltage coil, can automatically detect and dynamically display the work humidity of phase coils and also have the functions of over-temperature alarm and trip.

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.
