Technical Advantages of epoxy resin cast dry-type transformers:

1.High reliability: using advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, and a service life of 30 years.

2. Zero pollution operation and maintenance: Using epoxy resin cast insulation material to meet high fire and explosion requirements, especially suitable for densely populated or enclosed spaces; Oil-free cooling system, eliminating the risk of oil leakage, in line with environmental protection certification; Fully sealed structure to achieve maintenance-free design, the whole life cycle operation and maintenance costs reduced by 60% +.

3. Wide voltage range adaptation: Support 6.6kV to 35kV medium and high voltage grid access, covering industrial and commercial power distribution, rail transit, new energy grid connection and other scenarios, and optimize the energy efficiency performance of different voltage levels through segmented winding design.

4. Efficient heat dissipation and weather resistance: Natural air cooling (AN) or forced air cooling (AF) mode, combined with IP23 and above protection level, can withstand -40 ° C to + 120 ° C extreme environment, humid, dusty, corrosive gas environment can still operate stably.

Quality Assurance

• 100% routine testing including:

Lightning impulse (170kV) / Partial discharge (<10pC) / Temperature rise validation

• Cerifications: IEC 60076, IEEE C57.12.01, CE, UL
