One phase cast resin transformer
Single-phase dry-type transformers TP1HSN are modern products with upper voltage windings cast in epoxy resin in a monolithic form. Windings are perfectly protected against moisture and heat dissipation is excellent.
TP1HSN series transformers are mainly used as auxiliary transformers in indoor applications.
The technologies of epoxy resin casting ensure high quality of electrical insulation of the device. The transformers are manufactured basing on UNICORE cores that guarantee very low levels of no-load losses and excitation currents.
Upper voltage winding terminals are adapted for medium voltage fuse holders up to 53 mm in diameter.
