Switchgear Factory, Vadodara
L&T Switchgear, a part of the
Electrical and Automation business,
is India’s largest manufacturer of
low voltage switchgear, with the
scale, sophistication and range to
meet global benchmarks.
With over, Six decades of experience
in this field, the company today
enjoys a leadership position in the
Indian electrical market with growing
presence in international markets.
Larsen and Toubro entered into
medium voltage field by acquiring
Malaysian company TAMCO in 2008.
TAMCO has over four decades of
experience in MV switchgear and
supplied to large number of
customers worldwide.
Our ranges of MV products are
manufactured at various factories
across the world. In India these are
manufactured at L&T’s state of
the art facility at Ahmednagar.
Our MV products have worldwide
acceptance in sectors like Metals,
Power, Oil & Gas, Petrochemicals,
Infrastructure, Buildings, etc.
1 ABOUT US
Ahmednagar MV Manufacturing Facility
Air Insulated Switchgear (AIS) is used for control and protection of electrical power
distribution system. In our AIS, Vacuum Circuit Breaker (VCB) is used as the switching
device with air as the insulating medium in a metal clad enclosure. The protection and
control is offered by numerical relays.
The VCB is type tested as per IEC 62271-100 and the metal clad enclosure is type
tested as per IEC 62271-200, at reputed international laboratories viz. CPRI, ERDA,
CESI, KEMA, ASTA to assure highest quality standards.
The AIS panel is available for the system voltage of 3.3kV, 6.6kV, 11kV, 22kV, & 33kV
and for current ratings upto 3150A with natural cooling. The short circuit ratings are
available upto 50kA for 3 sec for 11kV & 31.5kA for 3 sec for 33kV. To prove its
suitability for use in severe climatic conditions, the switchgear has been subjected to
climatic aging tests according to IEC 60932, and proven to Design Class 2 (the highest
class). The switchgear has been designed and tested as per IEC 62271-200 to ensure
the safety of the operator in the event of an internal-arc fault. Arc vents are provided in
the busbar, cable and VCB compartments.
The switchgear has also been successfully tested to withstand seismic forces of 5-7 on
the Richter scale, in accordance with IEC 60068-3-3.
