Dry type transformer
SCB Dry Type power distribution transformer
Product Overview:
The reel core fully sealed distribution transformer is a new
generation of low noise and low loss transformer developed in
recent years.
Its iron core has no joint, greatly reduces the no-load loss and
no-load current, reduces the no-load current by 60%~80%, the high
and low coils are continuously coiled on the core column, the
winding is tight, the concentricity is good, and the product is
enhanced more.
Anti-theft performance. The noise decreased by more than 10
decibels.
The temperature rise is low 16-20K. Because of the continuous
winding of iron core (cross section is pure circle), the
orientation loss of silicon steel sheet is fully utilized, and the
no-load loss is reduced by 20%~30%.
The low voltage winding with capacity in the 630~2500kVA enclosure
is made of cylinder or spiral structure with high mechanical
strength and balanced ampere distribution. The product has good
short circuit resistance.
The positioning structure is added to the body so that it does not
produce displacement during the transportation process, and all
fasteners are equipped with fastener nuts to ensure that the
fasteners are not loose during the long run of the product and meet
the requirements of the non
core lifting.
The product surface is painted, primed and topcoat after
degreasing, rust removing and phosphating. It can meet the special
requirements of metallurgy, petrochemical system and wet dirty
area.This series of products has beautiful appearance, small size,
and can reduce the
installation area. It is an ideal free maintenance quality product.
Functions & Features
1.Safe, fire-retardant, pollution-free, can be installed directly
in the load center.
2.Maintenance-free, easy to install and integrated operation cost
is low.
3.It has good moisture-proof performance and can operate normally
under 100% humidity.
4.Low loss, low partial discharge, low noise, cooling ability,
forced air cooling conditions can be 150% rated load operation.
5.It is equipped with perfect temperature protection control system
to provide reliable guarantee for transformer safe operation.

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.
