IMB Current Transformers

IMB oil-minimum current transformers are based on a tank type (hairpin) design with over 60 years of ABB experience. It is the most sold current transformer worldwide.

Comprehensive service records show that the failure rate of IMB current transformers is up to four times lower than the industry average. More than 160 000 units have been delivered and installed all over the world from desert to arctic climates.

All our current transformers are tailor-made. Thanks to the combination of different tank sizes, expansion systems, primary windings etc, we can meet most customer requirements from 36 up to 800 kV.
The IMB current transformer is available with either porcelain or silicone rubber insulators.
