TP1HSN-4/24B

One phase cast resin transformer

TP1HSN-4/24B

windings and core cast in epoxy resin •  various fuse holders can be installed on PRI terminals •  rated power 4 kVA  •  system voltage up to 24 kV

Single-phase dry TP1HSN type transformers with rated power of 4 kVA are modern devices made up in the form of monolithic epoxy-resin casts. The technologies we use ensure high quality of electrical insulation of the device.

TP1HSN transformers are built on the base of the UNICORE core and are characterized by very low excitation loss. They are primarily used as auxiliary transformers.

Fuse holders can be installed on the terminals of upper voltage.
