TP1HSN-2.5/7.2A (…B)

Single-phase cast resin transformer

TP1HSN-2.5/7.2A (...B)

windings cast in epoxy resin •  chambers for fuses formed in the casting •  two versions: with core in horizontal (A) and vertical (B) arrangement •  rated power 2.5 kVA  •  system voltage up to 7.2 kV

Single-phase dry-type transformers TP1HSN are modern products with lower and upper voltage windings cast in epoxy resin. Windings are perfectly protected against moisture and heat dissipation is excellent. The technology of epoxy resin casting ensures high quality of electrical insulation.

Medium voltage fuses are mounted in chambers formed in the casting. In addition, fuses are covered with insulating guards made of silicone rubber.

UNICORE cores guarantee very low levels of excitation currents and excitation losses.

Transformers TP1HSN-2.5/7.2 are manufactured in two versions: with core in horizontal arrangement (A) and with core in vertical arrangement (B).
