2 off 145kV Dead Tank Outdoor Circuit Breakers
15 off 33kV Surge Arrestors
2 off 33kV NER
58 off 36kV Post Insulators
2 off Earthing Auxiliary Transformer
4 off Gevea 33kV Disconnector + Earth Switch
2 off Sadtem 36kV outdoor oil Voltage Transformer
3 off Post Current Transformer
3 off Slip‐Over Current Transformer

‐ Supply & installation of galvanised support Steel Structures for installation of all switchgear, main plant & ancillary equipment.
