SCB11-30-2500 10kV T-5 Three-Phase Dry-Type Epoxy Resin Power Transformer

The SC(B) series dry-type epoxy resin transformer is flame-retardant, fire-safe, explosion-proof, maintenance-free, environmentally friendly, compact due to its sealed winding, and can be installed directly at the load center.

At the same time, a scientific and intelligent design and casting process allows the product to have reduced partial discharge, lower noise levels, and superior heat dissipation capacity. With forced-air cooling, it can operate for extended periods at 125% rated load. It is equipped with an intelligent temperature controller with fault alarm, overtemperature alarm, overtemperature shutdown, and black box monitoring functions.

It is connected to a computer via an RS485 serial interface and can be centrally monitored and controlled. Due to the above characteristics, the product is widely used in power transmission systems such as hotels, restaurants, airports, high-rise buildings, commercial centers, residential areas, and other critical locations, as well as in subways, smelters, ships, offshore drilling platforms, and other environmentally sensitive locations.

Product Features

The high-voltage winding is made of enameled copper wire or film-wrapped copper wire, while the low-voltage winding is made of copper foil. The high-voltage winding is filled with fiberglass. Unfilled epoxy resin is used for the vacuum casting, which, after curing, forms a solid unit with high mechanical strength, low partial discharge, and high reliability.

Fireproof, explosion-proof, non-polluting, and environmentally friendly. It can be installed at the load center.

The core material is made of high-quality cold-rolled oriented silicon steel sheet with a laminated structure with a full beveled seam.

The coil does not absorb moisture, and the core and clamp are specially treated to withstand high relative humidity and other harsh conditions. Intermittent operation without dehumidification.

High resistance to short circuits, lightning impulses, and overloads.

Thin resin insulation layer inside and outside the coil, good heat dissipation.

Low losses, good energy-saving effect, economical operation, and maintenance-free operation.

Small volume, light weight, small footprint, and easy installation.
