The SC(B) series epoxy resin dry-type transformer is flame-retardant, fireproof, explosion-proof, maintenance-free, and environmentally friendly. Its windings use a sealed structure, resulting in a compact design that can be installed directly at the load center. The scientific design and casting process minimize partial discharge, reduce noise, and provide strong heat dissipation. Under forced air-cooling conditions, it can operate continuously at 125% of its rated load.
The transformer is equipped with an intelligent temperature controller featuring fault alarms, over-temperature warnings, automatic shutdown on overheating, and a “black box” function. It can connect to a computer via an RS485 serial interface for centralized monitoring.
Thanks to these features, this transformer is widely used in transmission systems for important locations such as hotels, restaurants, airports, high-rise buildings, commercial centers, and residential complexes, as well as in harsh environments like subways, smelting plants, ships, and offshore drilling platforms.

Product characteristic
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.
Flame retardant, explosion-proof, no environmental pollution, environmental protection. It can be installed in the load center.
The core material is made of high quality cold-rolled oriented silicon steel sheet with full inclined seam laminated structure.
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 environments. Intermittent operation without dehumidification treatment.
High resistance to short circuits, lightning impulse and overload.
Thin resin insulation layer inside and outside the coil, good heat dissipation performance.
Low loss, good power saving effect, economical operation and maintenance free.
Small volume, light weight, small floor space and convenient installation.
