Contact SupplierWe are bracketed among the trusted Manufacturers, Suppliers and Exporters of Type Test Transformers. The Transformers we make available are highly efficient and are highly energy saver. Our Transformers undergo various quality-tests before the final dispatch of the Transformers. Bulk orders of the Transformers are processed by us as per the specific requirements of the buyers.
Type Test Transformers :
These are our range of distribution transformers which are type tested from ERDA. We have various approved ratings of our different transformers. Such as we have 3 and 4 Star rating respectively approved for our 16, 25, 100, 200 KVAtransformers.l
The transformers besides routine testing undergoes type test in which following test are done :
Lightening Impulse Test
Short Circuit Test
Temperature Rise Test
Air Pressure Test
Vacuum Test
Magnetic Balance Test
Permissible Flux Density and Overfluxing test
These Transformers are highly efficient and are highly energy saver. They have fairly low losses. GTB is approved supplier of various state electricity boards such as PSPCL, HPSEB etc. We participate in tenders of star rated transformers and also participate for repair tenders of state Electricity boards
