Product Features
Insulation Material
Epoxy resin insulation: Transformer windings are fully cast in epoxy resin, offering excellent insulation, moisture resistance, and high-temperature resistance, giving the transformer high reliability and durability.
Safe & Reliable
SCB series dry-type transformers offer excellent fire performance: containing no oil, they eliminate concerns about environmental pollution or fire risks caused by oil leakage. The transformers have a strong tolerance to short-circuit currents and overvoltages and maintain stable performance even in harsh environments.
Eco-Friendly Features
Pollution-free: Epoxy resin insulation makes the product environmentally friendly, non-toxic, and harmless. No oil cooling medium is needed, eliminating the possibility of oil contamination and fully meeting environmental protection and energy-saving requirements.
Excellent heat dissipation
Available with natural air cooling (AN) or forced air cooling (AF). When the transformer load is high, forced air cooling can increase the transformer's capacity output.
Mechanical Performance and Durability
High mechanical strength: epoxy cast windings deliver good mechanical performance with high resistance to short circuits and impact. Moisture resistance: the transformer adapts well to its environment, making it especially suitable for high-humidity and dusty conditions.
Easy Operation and Maintenance
SCB series dry-type transformers require no complex maintenance, making them ideal for environments that need reliable operation with minimal maintenance effort.
