The presented switchgear is a continuation of the project, the previous two versions were switchboards for transformers with a power of 75MVA, while the one shown below is a control cabinet for a transformer with a power of 100MVA.
The prefabricated switchgear was shipped to Canada to areas with harsh weather conditions. The special design of the switchgear included ensuring its uninterrupted operation in atmospheric conditions down to -50°C by using PREMIUM thermal insulation.
