VT Switchgears & Transformers

Peenya, Bangalore, Karnataka

A reliable power supply presupposes a sufficiently large supply system with high-performance transformers. The high quality standards set by VTST are appreciated all over and these are applied to development, manufacture, installation and commissioning of power transformers for power stations, transformers stations and auxiliary plants for generating stations, special transformers for industry and transport, reactors and accessories.

VTST manufactures a wide range conventional, sealed type/ outdoor type, 3 Ph, 50 Hz, oil immersed, ONAN/ ONAF/ OFWF cooled, step up/ step down, multi winding with Al/ Cu conductor, Continuous duty distribution transformers ranging from 15 KVA to 2500 KVA with all voltage class and up to 33 KV. These transformers can be free breathing, fitted with a conservator. The liquid filled range is cooled by tank - mounted plate radiators on the side of their tanks. The latter being known as conventional type transformer.  

Dry type Transformers, class 'H' insulated, have insulating materials which are with high dielectric strength and are capable to withstand high temperatures. The temperatures are generally made to comply with IEC-60076/IS-2026/IS-1171.Range up to 1600 KVA of 11 KV Class.   Advantages:     Use of non-biodegradable materials makes these suitable for strict   environmental conditions.   No fire or explosion hazards because of use of nonflammable   materials & absence of any liquid insulation.   Non-requirement of oil sump makes these ideally suitable for   installation near load centers thus reducing cabling costs and improving voltage regulation. Owing to adherence to International Quality norms and prompt customer services, VTST has an excellent brand image and an ISO 9001:2000 certified company with it’s headquarter in Bangalore (INDIA).     Zero Maintenance:       Drastically reduced maintenance and cleaner looks because of absence of any insulating liquid.   A lifecycle analysis would reveal the cost-effectiveness of Dry type Transformers in the long run   though these require higher initial cost.   Easy handling and access to active parts for inspection.   The Dry type Transformers are designed for required BIL values and are tested for dynamic short   circuit.
