MEDIUM VOLTAGE INSTRUMENT TRANSFORMERS

CT-Current Transformers, Indoor Mould Type, max. 24 kV
VT-Voltage Transformers, Indoor Mould Type, max. 24 kV
Special Low Voltage Transformers Type, max. 24 kV

Trafoindo has expanded its scope of production, to cover the full manufacturing program of medium voltage 24 kV Instrument Transformers consisting of indoor/outdoor types :

1. MV Current Transformers, and

2. MV Voltage Transformers

with the trademark "TRAFINDO" (TRAFO INSTRUMENT INDONESIA)

Based on experiences in adapting Grain Oriented Silicon Steel Core, Trafoindo designed a compact Instrument Transformer, added on to the application of "EXPOXY RESIN CASTING" technology for Indoor Instrument Transformers and for Outdoor Instrument Transformers, resulting the core and coil of the Instrument Transformers entirely encapsulated with EXPOXY RESIN, thereby ensure a product with High Reliability, Moisture Resistant, Fire Resistant, Maintenance Free and Shock Proof.

Below are seven examples of "TRAFINDO" Instrument Transformers :
