100kVA Single Phase Pad Mounted Transformer

The 100 kVA Single Phase Pad Mounted transformer adheres to a compartmental-type structure in line with IEEE Std C57.12.28 or IEEE Std C57.12.29 standards. It consists of a tank housing high-voltage and low-voltage cable terminating compartments, thoughtfully positioned side by side along one face of the transformer tank. In this configuration, the high-voltage compartment, fitted with two internally connected high-voltage bushing wells and inserts, a 4-position loadbreak switch, a 5-position tap changer switch, and a bayonet fuse, is situated alongside the low-voltage compartment featuring three stud L.V bushings and an oil level gauge.
