One phase cast resin transformer
uzwojenia w odlewie z żywicy epoksydowej • możliwość montowania pionowych opraw bezpiecznikowych • moc znamionowa 5 kVA • napięcie znamionowe do 24 kV
Single-phase dry-type transformers TP1HSN are modern products with lower and upper voltage windings cast in epoxy resin. TP1HSN transformers are designed for indoor applications. Windings are perfectly protected against moisture and heat dissipation is excellent. The technology of epoxy resin casting ensures high quality of electrical insulation.
UNICORE cores guarantee very low levels of excitation currents and excitation losses.
Medium voltage fuse holders with outer diameter of 53 mm can be mounted on upper voltage terminals.
Transformers type TP1HSN are used mainly as auxiliary transformers.
