EDC provides comprehensive High Voltage services encompassing design, installation, and maintenance. We work with clients and distributors to develop documentation for new HV connections, create safety plans with technical diagrams, and design detailed substation layouts including earthing and fire protection systems.

Our installation services include coordinating civil and electrical substation work, employing four specialised HV terminators (certified up to 33kV and 66kV), installing underground cables with mandatory testing, and providing upgrade teams across various states.

For maintenance, EDC coordinates planned HV shutdowns involving safety planning, systematic isolations, servicing switchgear and transformers, conducting protection system testing, oil analysis, thermographic surveys, and generating comprehensive reports with recommendations.
