SCB Dry Type power distribution transformer
Product Description
THis product has the characteristic of anti-flaming,anti-explosion,
damp-proof, dust proof. The adoption of integral casting coil
structure makes it
high mechanical strength, small partial discharge capacity, High Reliability.
This product also has the advantages of safety, energy saving, environmental protection, and maintenance free. It can be installed in moist and dirty environment.
It is suitable for airport, station, wharf, the subway, power plant, substation, hospital, hotel,business center, sports venue, high-rise building, residential area and industrial and mining enterprise etc.
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.
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.

All products of the company have passed the national type test like CCC, CQC , CTQC and other
national mandatory product certification, and has a perfect quality, occupational health and
environmental management system certification system. Our products have passed ISO9001, 2000
and other international quality system certification.
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.
