Transmission & Distribution

MECON renders total service starting from study, planning, design, engineering, supply, erection, testing and commissioning in the field of Power Transmission and Distribution. MECON has been involved in design, engineering and commissioning of large number of EHV sub-stations/ switchyards having voltage levels 400/ 220/ 132 kV and HV substations having voltage levels of 33/ 11/ 6.6kV.  These sub-stations have been either main receiving sub-stations or major step down sub-stations of large plants or sending end sub – station of power plant. Many of these sub-stations are having transformation capacity of the range of 500 MVA or more.
