Installation and testing of SF6 and air-insulated circuit breakers, disconnect switches and earthing switches.

02Instrument transformers

Installation of CTs, VTs and combined units, with accuracy class verification.

03Busbar systems

Rigid tubular aluminum/copper busbars and flexible conductors, with corona shields and joint kits.

04Grounding systems

Design validation and installation of copper-clad steel or bare copper grids, with fall-of-potential and step/touch tests.

05Protection and control

Installation and wiring of relay panels, interface panels and RTUs, and integration with SCADA and automation networks.

06AC/DC auxiliary services

Supply, installation and commissioning of AC panels, DC systems, chargers, inverters and battery banks.

07Testing and commissioning

Primary and secondary injection, relay coordination, point-to-point checks, functional logic tests and energization support.

08Civil works
