Dry-Type Transformer Technology
Our non-encapsulated coil three-phase dry-type power transformers utilize an approved Nomex insulation system. They offer industry-leading safety, reliability, and energy efficiency. Designed for fire resistance and explosion-proofing, these units require minimal maintenance and exhibit superior performance in partial discharge, no-load loss, and noise control.
Engineered for harsh environments, they operate effectively in high-humidity or polluted areas near coastal regions. Ideal for high-safety requirement zones like skyscrapers, airports, subways, hospitals, and nuclear plants. Featuring epoxy-sealed windings, the design is flame-retardant and pollution-free.
