Transformador de potência de distribuição de resina epóxi de tipo seco 33kv 35kv

The SC(B)10 Series 33kV/35kV Dry-Type Epoxy Resin Transformer is designed for heavy-voltage power distribution in tough applications. Its flame-retardant epoxy-insulated windings and advanced cooling system make the transformer a safe, reliable, and environmentally friendly means of working for industrial, commercial, and critical infrastructure applications.

Product Benefits:

Safety & Longevity

Flame Retardant (Class F): Self-extinguishing properties assured by epoxy resin encapsulation, providing better fire safety.

Explosion-Proof Construction: Best suited for hazardous conditions such as offshore platforms and chemical plants.

Zero Maintenance: Pollution-resistant design prevents corrosion, assuring longevity and removing the requirement for regular maintenance.
High Efficiency & Low Loss

Ultra-Low Partial Discharge: Achieved using precision vacuum casting and reinforced glass fiber, ensuring less than 5pC of partial discharge.

Noise Reduction: Silent operation (<60dB), thanks to F-grade core binding and air flow optimization.
Overload Capacity: Accommodates 40% continuous overload with forced-air cooling (AF) for increased flexibility and reliability.
Smart Monitoring & Control

Integrated Thermal Protection: Includes auto-shutdown, fault alarms, and “black box” data logging to monitor continuously.
Remote Management: With RS485 interface, allowing real-time monitoring via SCADA systems to guarantee efficient operation management.
Compact & Versatile

Space-Saving Design: Most appropriate for city area substations, skyscrapers, and underground locations.
