Product Details

2500KVA Three Phase Dry Type isolation Transformer NEMA3R

 

 

Feature

 

1. The energy consumption efficiency of the transformer reaches 99.26%, 8-15 percentage points higher than that of general products.
2. The enclosure meets the requirements of AWS certification (American Electrotechnical Association certification), Its load-bearing, heat dissipation, and rainproof performance meet NEMA3R standards (requirements for outdoor enclosure in North America).

3. HIGH SECURITY - VPI transformer has no combustible resin, halogen-free, non-combustion supporting, and flame retardant in use. It will not explode and release toxic gases, will not cause harm to the environment, other equipment, and the human body, and is insensitive to temperature, dust, and pollution.

4. The operation's partial discharge is small and will never crack. Its safety characteristics are especially suitable for places with high fire protection requirements and high population density.
