Describe Display

The SC(B) series dry-type distributing transformers (SC14, SCB14, SC18, SCB18) offer a compact, maintenance-free solution for medium-voltage power distribution. Their epoxy-sealed windings and superior thermal management deliver low partial discharge, quiet operation, and reliable overload performance. Integrated intelligent thermal controls provide real-time alarms, auto-shutdown, and black-box recording to safeguard equipment.

Equipped with an RS485 serial interface, these transformers support full remote monitoring and control via computer systems. Ideal for hotels, airports, hospitals, subways, offshore platforms, and other harsh or noise-sensitive installations, the SC(B) series ensures safe, efficient, and uninterrupted power delivery.
