Product Description

The SC(B) series epoxy resin dry-type transformer is designed to meet stringent safety and performance requirements. This transformer is characterized by its flame-retardant, fire-proof, and explosion-proof properties while also being maintenance-free and environmentally friendly. Its compact size is made possible by encapsulating the winding, allowing direct installation in the load center.

The product features a scientifically designed casting process which minimizes partial discharge, reduces noise, and enhances heat dissipation capacity. It is capable of operating continuously under a 125% rated load with forced air cooling. Equipped with an intelligent temperature controller, the transformer is capable of fault alarm, overtemperature alarm, overtemperature trip, and black box functionalities. It is connected to a computer via a RS485 serial interface, enabling centralized monitoring and control.

Due to its exceptional characteristics, the dry-type transformer finds widespread use in power transmission systems for a variety of critical applications. These include but are not limited to hotels, restaurants, airports, high-rise buildings, commercial centers, residential areas, subways, smelters, ships, offshore drilling platforms, and other harsh environment locations.

Product characteristic

The transformer's high-voltage winding is crafted from either enameled copper wire or film-wrapped copper wire, while the low-voltage winding is made of copper foil. The high-voltage winding is surrounded by glass fiber felt and is filled with epoxy resin without any filler in a vacuum state. This results in a solid structure with high mechanical strength, minimal partial discharge, and reliable performance.

This transformer is designed to be flame retardant, explosion-proof, and environment-friendly, with no risk of environmental pollution. It can be conveniently installed in a load center. The core material is composed of premium cold-rolled oriented silicon steel sheets in a fully inclined seam laminated structure.

Thanks to a special treatment process, the coil does not absorb moisture, allowing the transformer to operate effectively in high relative humidity and other challenging environments without the need for dehumidification treatment. Furthermore, it offers high resistance to short circuits, lightning impulses, and overloads.

The transformer's coil features a thin resin insulation layer both inside and outside, ensuring excellent heat dissipation performance. This not only results in low energy loss and substantial power savings but also makes for economical and maintenance-free operation.

In addition to its outstanding performance, this transformer boasts a compact design, making it lightweight and requiring minimal floor space for installation.
