3. Main Features
Energy Saving and Low Loss, Compliant with Latest Standard
Its no-load loss and load loss are significantly lower than those of SCB10, providing better power-saving effect in long-term operation and meeting energy efficiency requirements for new construction projects.
Dry-type and Oil-free, Fireproof and Explosion-proof
With epoxy resin casting structure, the transformer is flame-retardant and self-extinguishing, free of oil leakage and fire risks. It can be safely installed indoors, in basements and load centers.
Excellent Short-Circuit Withstand Capability
Windings feature high mechanical strength and reliable insulation performance, with strong resistance to impact and lightning stroke, ensuring stable and reliable operation.
Moisture-proof and Dust-proof, Strong Adaptability
It can operate stably in humid and dusty environments. No pre-drying is needed before restart after shutdown.
Maintenance-free and Long Service Life
Oil-free structure avoids leakage and daily oil maintenance. It has low operation cost and long service life.
Low Noise, Quiet Operation
Optimized core and structure design bring lower noise, making it ideal for residential areas, hospitals, schools and other noise-sensitive places.
Compact Size and Easy Installation
No oil pool or fire wall is needed. It supports direct floor installation with small footprint and convenient construction.
