Famous Buried Power Transformer Factories – SC(B) □ Series Epoxy Resin Dry Type Transformer – Changan Group

Product introduction

SC(B) series epoxy resin dry-type transformer is flame-retardant, fire-proof, explosion-proof, maintenance free, pollution-free, small in size, because of the winding is encapsulated, and can be directly installed in the load center. At the same time, the scientific and reasonable design and casting process make the product have less partial discharge, lower noise and stronger heat dissipation capacity. Under the condition of forced air cooling, it can operate for a long time under 125% rated load. It is equipped with intelligent temperature controller, which has the functions of fault alarm, overtemperature alarm, overtemperature trip and black box. It is connected with the computer through RS485 serial interface and can be monitored centrally and control.
Because of the above characteristics, the product is widely used in power transmission system, such as hotels, restaurants, airports, high-rise buildings, commercial centers, residential areas and other important places, as well as subway, smelter, ship, offshore drilling and platform and other places with bad environment.

Product features

1. The high voltage winding is made of enameled copper wire or film wrapped copper wire, and the low voltage winding is made of copper foil. The high voltage
winding is filled with glass fiber felt. In the vacuum state, the epoxy resin without filler is used for pouring, which forms a solid whole after curing, with high
mechanical strength, small partial discharge and high reliability.
2. Flame retardant, explosion-proof, no environmental pollution, environmental protection. It can be installed in the load center.
3. The core material is made of high quality cold-rolled oriented silicon steel sheet with full inclined seam laminated structure.
4. The coil does not absorb moisture, and the core and clamp are treated by special process, which can operate in high relative humidity and other harsh environment.
Intermittent operation without dehumidification treatment.
5. High resistance to short circuit, lightning impulse and overload.
6. Thin resin insulation layer inside and outside the coil, good heat dissipation performance.
7. Low loss, good power saving effect, economical operation and maintenance free.
8. Small volume, light weight, small floor space and convenient installation.
