Dry type transformer
SCB Dry Type power distribution transformer
SC(B)10, SC(B)11, SC(B)13 are the typical dry epoxy distribution
power transformer, they are fireproof, compact and mainly designed
for indoor use, and can be directly installed in the load center.
Dry transformers with high and low voltage windings are coated by a
thin layer of epoxy resin. It has the advantages of flame
retardant, self-extinguishing, moisture-proof, heat dissipation and
so on. It can go deep into load centers, such as high-rise
buildings, airports, wharfs, power plants, residential communities
or complete sets of substations.
The company's products are mainly used for power transmission and
transmission frequency of 50HZ, power network voltage of 10KV or
35KV, and the transmission and distribution of altitudes of 1000
meters and below. It can be used as power supply for rural and
regional power supply and rural water drainage and drainage,
outdoor installation, continuous use. With reliable technology,
high-quality materials, good economic performance, good reputation
and excellent service, our products have won unanimous praise from
new and old customers.
Benefits:
1. Low noisy
2. Low partial discharge
3. High mechanical strength and strong short circuit resistance
ability;
4. Strong impact resistance
Application
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.

Qualification Centre
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.
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.
