Our â1200 kVâ design of connectors has been in successful operation in Powergrid Corporation of India (PGCIL) at their 1200 kV trial substation in Bina, Madhya Pradesh since February 2012. These connectors are equipped with either HDG or Stainless steel fasteners. This further strengthens our hold in the 1200 kV segment. They meet the IS and NEMA standards for substation connectors.
