EL-Tech Controls manufactures and supplies the 12 KV Compact Substation in Chennai for distribution transformer centres, HT consumers, industrial plants, townships, hospitals and commercial buildings. Every panel is built at our Ambad MIDC, Nashik works, where we have made MV switchgear since 1995.
12 KV Compact Substation for Chennai's Power Distribution
Chennai is India's automobile and electronics manufacturing hub, with large plants at Sriperumbudur, Oragadam and Irungattukottai and an expanding IT corridor along OMR. All components are housed in one enclosure with separate I/C and O/G compartments, natural ventilation and IP55 protection (IEC 60529), with doors fitted with double-point closing and flush handles for padlocking.
In Chennai, power is distributed by TNPDCL (formerly TANGEDCO). Our panels are approved by MSEDCL (C.E. Distribution), PWD (C.E. Electricals) and Garrison Engineers (MES), and are type-tested at ERDA, Baroda. Share your utility or consultant specification and we will confirm compliance before manufacturing. Each panel is built to suit the transformer rating and site layout, for indoor or outdoor use.
Product Details
The compact substation is designed for personnel safety where H.T. equipment is located in populated areas. It is designed and tested in accordance with IEC 62271-200 and contains a metering kiosk (CT and PT) and a medium voltage load break switch, suitable for all 11 KV H.T. consumers.
Material and Construction
- Frame made of heavy steel sheet that protects all mechanical parts from dust, insects and rain.
- Simple, compact and tested construction that does not age or deteriorate during long periods of inactivity.
- Epoxy resin supporting insulators that withstand the electrodynamic stresses guaranteed by the switch.
- 100% non-porous powder coating with provision for cable entry.
Safety Mechanisms
- Independent quick break and make operating mechanism, with springs always in the 'off' position.
- Load break switch with fully interlocked earthing blades.
- Interlock between LBS and door: the door cannot open while the LBS is engaged.
- Interlock between front door and LBS: the LBS cannot be engaged while the front door is open.
- Interlock between LBS and earth switch: the earth switch disconnects first, and only then does the LBS engage.
- Blowing of a single HRC fuse trips the LBS immediately to prevent single phasing.
Performance
- The arc is extinguished quickly by self-generated air through three piston cylinders, one per pole, mounted in axis with the insulators.
- The volume of blown air and the contact separation speed ensure reliable switching even in harsh conditions.
