Dry type transformer
Features
SG10 transformer has no flammable resin, and it does not support
combustion during usage.
It can be flame retardant and will not explode and release toxic
gases, not cause harm to the environment, the other equipment and
human body.
It is not sensitive to humidity, dust and pollution. It will not
cause partial discharge and never have the possibility of
"cracking".
High reliability
The high and low voltage coils are all made of NOMEX insulation
material, and are impregnated with H-class solventless impregnating
varnish multiple times by VPI vacuum pressing equipment, and baked
at high temperature for many times.
The product is Class H (180 ° C), and the main insulation material
is Class C (220 ° C), and it has strong overload capacity, and good
short-circuit resistance. Allow 20% overload for operation in well
ventilated conditions.
Energy saving and environmental protection. After the product life,
steel, iron and other materials are easy to recycle;All used NOMEX
papers will not release toxic substances when burned; Other
insulation materials can degrade and won't pollute the environment;
Low loss and energy saving of products;Low noise and flexible
design.
Appplication
This series of non-encapsulated coil H-class insulated three-phase
dry-type power transformers, in addition to the advantages of the
SC series, the well-designed coil structure and vacuum impregnation
process make the SG(B)10 transformer have no partial discharge, and
throughout the life cycle there is no cracking phenomenon, and
there is no drop in insulation level. It features with low loss,
low noise, strong thermal shock esistance, large overload capacity,
high fire resistance, flame retardant, non-toxic,
self-extinguishing, fireproof. Under high temperature open flame
combustion, SG(B)10 transformer has almost no smoke generated; It
will not produce harmful gases, and does not pollute the
environment, and is not sensitive to humidity and dust. It can be
installed in the dirty and humid environment near the lake and the
river, and in areas with high fire protection requirements and high
load. It is suitable for high-rise buildings, airports, stations,
terminals, subways, hospitals, power stations, metallurgical
industries, shopping centers, and residential areas and in
petrochemicals, nuclear power plants, nuclear submarines, etc.

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 hasa 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.
