About usTechno Power is an ISO 9001 : 2008 Certified manufacturer of Power and
Distribution Transformers from 5 KVA to 15000 KVA upto 11-22-33 KV Class, Single
& Three Phase.
We are manufacturing oil filled distribution transformers 100 KVA to 10 MVA and
furnace and power transformers upto 15 MVA 66 KV class. We design and
manufacturer a complete range of transformers in our class. We at Techno Power see
that our customers get the best of the products and an excellent after sales service
support.
We firmly believe in quality and that too backed up by after sales services to their
installations throughout INDIA.
QualityThe Company has well-established quality systems to ensure quality at all stages
and Total Quality Work Culture. The Company today has the latest certification for
compliance to ISO 9001 : 2008. & IS-1180 (Part-1) The Company has been adopting
progressive measures visualizing quality as a key strategy to stay competitive in the
business. Customer satisfaction has been in our agenda right through the beginning.
Techno Power manufacture wide range of Oil Cooled
Distribution Transformers. The standard range is up to
5000 KVA. A Distribution Transformer is a Transformer
that provides the final voltage transformation in the
electric power distribution system, stepping down the
voltage used in the distribution lines to the level used by
the customer.

In cast-resin dry-type transformers, the complete encapsulation of primary and secondary winding in epoxy resin prevents penetration of moisture into windings in epoxy resin prevents penetration of moisture into windings. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity.

Cast Resin Dry Type Transformer
TECHNICAL SPECIFICATIONS industrial, Substation &
Distribution purpose manufacturing range upto 2MVA. 11KV, 22
KV naturally air cooled. A dry type transformer has an iron core,
vacuum pressure resin impregnated high voltage windings and
low voltage windings. The Low voltage winding is constructed
with conductors. Dupond nomex insulating material includes
and apparatus to secure the windings in place during a vacuum
and pressure resin impregnation process. The result is a coil that
exhibits high short circuit protection due to the tightly bond
conductors comparable to completely resin encased molded
transformers at a substantially reduced cost.
