FREQUENCY TRANSFORMERS - DRY-TYPE TRANSFORMERS
At FREQUENCY TRANSFORMERS, we offer fast quotes, flexible planning, and on-time delivery for cast resin and VPI/VPE dry-type transformers. We provide the optimal solution for EPCs, importers, and end users with fire safety, low maintenance, and resistance to indoor and corrosive environments.
Why a Dry-Type Transformer?
- Fire safety: Flame-resistant, low smoke emission (F1/NHN material options)
- Low maintenance: No oil changes, no risk of leakage, long lifespan
- Indoor suitability: Safe use in hospitals, shopping malls, tunnels, data centers, residential, and industrial facilities
- Environmentally friendly: Low environmental impact due to no oil or risk of leakage
