NirouTrans Company

History

Nirou Trans Co. which is established in 1990 , is the reputable manufacturers of instrument Voltage and Current Transformers in the range of 6kV up to 550 kV, Condenser Bushings in the range of 72.5kV up to 420kV,Generator Circuit Breakers ,Coupling Capacitors ,Wall Bushings and Combined Instrument Transformers up to 36kV. The technology of manufacturing the instrument transformers is acquired from ABB corporation, Sweden ,condenser bushings from HSP Germany and generator circuit breakers from ABB, Swiss.
Tens of thousands of instrument transformers and other products of this company are operating successfully for years in electrical installations of several countries in various climate conditions. Quality and conformity with customers’ requirements have been the main policy of Nirou Trans Co. All the instruments transformers and condenser bushings are type tested in KEMA laboratory, Holland ,and the routine tests are performed according to international well known standards or customer requirements , the related test report will be submitted for each instrument.
