Product features:

SC(B)14 series is high‑efficiency level 2 epoxy resin vacuum cast dry‑type distribution transformer.
The windings are fully encapsulated by epoxy resin, featuring fire‑resistant, explosion‑proof and pollution‑free performance. It delivers low loss, low noise and strong short‑circuit withstand capability.
Equipped with intelligent temperature control system, it supports forced‑air cooling for short‑term overload operation. Good moisture resistance allows reliable operation under high‑humidity conditions. Compact size saves installation space, widely adopted in indoor public buildings, industrial plants and data‑center power distribution projects.

Performance characteristics

High‑efficiency & Energy Saving
Level 2 high‑efficiency design reduces no‑load & load losses. Low noise and remarkable energy‑saving effect, supports maintenance‑free long‑term running.
High Safety Performance
Epoxy vacuum encapsulated winding structure, fire‑resistant and explosion‑proof. High mechanical strength, outstanding short‑circuit withstand and thermal stability, controlled low partial discharge.
Heat Dissipation & Overload Capacity
Optimized internal air‑duct design ensures good heat dissipation. Forced‑air cooling allows short‑term overload operation. Good moisture resistance adapts to high‑humidity harsh working conditions.
Intelligent Temperature Protection
Built‑in temperature sensor cyclically displays 3‑phase winding temperature. Automatically triggers cooling fans; provides overtemperature alarm and trip signal output for system interlock.
Compact & Custom‑Built Solution
Small footprint and light weight cut civil‑work & installation expenditure. Optional accessories include anti‑condensation heater and special tap‑changer for site‑specific requirements.
