Cast resin current transformers (up to 36kV)

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

Indoor Installation

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, INA,UNA can be used.

INA

Voltage:
12, 24 and 36 kV

Current:
Up to 4000 A

UNA

Voltage:
12, 24 kV

Current:
Up to 960 A

NICT

Voltage:
12, 24 kV

Current:
Up to 960 A

Outdoor Installation

The main insulation of these of these instrument transformers is epoxy resin compound based on sylco alphatic resin cast and it can keep the insulation properties under different climatic conditions. AGE,APE models are available for different applications.

APE

Voltage:
12, 24 and 36 kV

Current:
Up to 960 A

AGE

Voltage:
12, 24 and 36 kV

Current:
Up to 4200 A
