IMB oil-minimum current transformers are based on a tank type (hairpin) design and available with porcelain or silicone rubber insulators.
Hitachi ABB Power Grids current transformers are tailor-made. The combination of different tank sizes, expansion systems, primary windings etc.,makes it possible to meet most customer requirements from 36 kV up to 800 kV.
More than 170,000 units have been delivered and installed all over the world - from desert to arctic climates by Hitachi ABB Power Grids. Comprehensive service records show that the failure rate of IMB current transformers is up to four times lower than the industry average.
