Home > Products > Dry Type Transformer > Epoxy resin dry type transformer
The F-Class resin-cast dry-type distribution transformer is designed for safe, efficient, and reliable indoor power distribution. Its high- and low-voltage windings are encapsulated with high-quality epoxy resin, providing excellent flame resistance, self-extinguishing performance, moisture resistance, and electrical insulation.
The transformer does not require insulating oil, eliminating the risk of oil leakage and significantly reducing fire and environmental risks. Its compact structure allows installation close to the load center, helping reduce low-voltage cable losses and improve overall power-distribution efficiency.
With rated capacities from 30 to 2,500 kVA, high-voltage options from 6 to 11 kV, and a standard 0.4 kV low-voltage output, this three-phase cast resin dry-type transformer is suitable for high-rise buildings, airports, ports, power plants, residential developments, industrial facilities, and complete substations.
