SCB Dry Type power distribution transformer
Product Overview:
Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically. The core is made of high-permeable grain-orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials , scientific
management, and perfect inspection means.
Reliable Structure
The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble and has low local discharge, high reliability, and long service life.
The high-and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture; the clamps of core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments.
Excellent Materials
Flame retardancy , explosion-proof and no environmental contamination. The insulating materials in the coil such as glass fiber are self-extinguishing and they will not cause fire by the arc resulted from short-circuit . The resin will not generate toxic or harmful gas under high
temperature.
Gas duct is embedded inside it to enhance the radiation power and over-load capacity. Low loss and low noise. The core is lapped with 45 full-miter? and the step-type lamination effectively improves distribution of magnetic flux at core corners, and greatly reduces the no-load loss and
the nose level.
It highly withstands short-circuit and lightning impact.Small in volume, light in weight, safe in running and free of maintenance. As per users’ requirements the transformer may be provided with casing and blower fan.

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.
