Description

The SC(B) series dry-type transformers are designed for high efficiency, reliability, and safe operation in modern power distribution networks. Rated for 20 kV medium-voltage systems, they provide stable low-voltage supply to a wide range of applications, including urban power grids, high-rise buildings, hospitals, schools, commercial centers, airports, subways, tunnels, ports, industrial facilities, and renewable energy projects.

Advantages

• High Efficiency & Low Loss: Reduces energy consumption and operational costs.

• Safe & Environmentally Friendly: Oil-free, flame-retardant insulation prevents fire risks and toxic emissions.

• Reliable in Harsh Environments: Moisture-resistant coils and anti-corrosion cores allow operation in high humidity without dehumidification.

• Compact & Flexible Installation: Lightweight design saves space and enables placement closer to load centers, reducing cabling costs.

• Strong Electrical Performance: High short-circuit withstand and lightning impulse resistance ensure stable operation.

• Low Maintenance: Robust design minimizes service needs and ensures long-term reliability.
