Cast resin voltage transformers (Up to 36kV)

These transformers are used to separate measuring and protection equipment from high voltage circuits and to transform the voltage to the values required by the measuring and protection equipment.

Indoor Installation

Indoor Cast resin inductive transformers Niroutrans

These transformers can be installed in medium voltage coupling panels, incoming and outgoing feeder in a substation.
The main insulation of these instrument transformers is epoxy resin compound cast in high vacuum, with superior dielectric and mechanical properties. Depending on the required specification, one of the models, 4VPA1, 4VPA, GUPT, TIPT can be used.
