The basic material of KSZ21-29-630kVA Transformer Substation is concrete complying with electrical, thermal and mechanical requirements set out in MSZ EN 62271-202:2014 standard specifications. The transformer substation is monolithically cast as a single piece one, built without gap. The compression strength of concrete conforms to Grade C30/37. The transformer substation consists of three compartments, namely a medium voltage switchgear compartment, a transformer compartment and a low voltage switchgear compartment. The medium voltage switchgear compartment allows to install SF6 gas insulated switchgear units and an air insulated measuring cell. The transformer compartment formed inside the substation allows to install a transformer with a rated power of up to 630 kVA.
