At our works
we have the capability and more enough experience to
repair and fully service of any make of transformers up
to 20MVA, 66KV class.
We have competent and well experienced engineers and
technicians to do the independent job of assembly,
commission, maintenance repairing & trouble shooting
transformers. Our engineer and consultant can re-design
the repairing job for better cooling and enhance the
rating
We can also make transformers life healthy by
overhauling, replacement of entire insulation including
conductor covering.
Repairs of Power & Distribution Transformer up to 20 MVA
66KV class including of winding, insulation and high
quality CRGO core material to reduce the no load losses
of the transformer.
Conversion of vector group :
General industries requires Dyn11 vector group, same can
be change by change in winding & or by change in
connection to YD11,Dy5,Yd0 etc.
Voltage ratio conversion :
Converting voltage ratio is possible to higher to lower
voltage ratio i.e.
66KV/33KV/22or11KV,33KV/22KVto33KVto11KVor33KVto6.6KVetc.
Offload to On load tap changer :
This can be done by changing of primary winding and
change in fitting arrangement and modification of tank
so that the transformer can arrange voltage fluctuations
without switch of the transformer.
Conversion of cable box to bare
bushing and bare bushing to cable box:
This type of conversion made by modification of top
cover or tank to maintain require Ampere capacity.
Radiator change:
Old type radiator like tube radiator can be change by
using directly welded or flange type radiator, it is
also can be replaced having more fins for more cooling
of the transformer.
Supply & Change of General &
Additional Accessories:
Supply & change of general accessories like Drain Valve,
Oil Filter Valve, Silica Gel Breather, Plain Oil Gauge
etc & additional accessories like buchholz Relay, OTI,
WTI, Marshaling Box, Dial Type Thermometer and special
type AVR, RTCC & OSR.
Possible test can be done at site and report for
possible cause of transformer failure modification of
accessories.
