 Product
Range
50 kVA to 5000 kVA, 11 kV & 33 kV Class
suitable for Indoor applications with off
circuit tap links, off circuit tap switch,
on load tap changer (Indigenous & Imported).
Standards
The Dry Type transformer are manufactured to
comply with National International Standards
BIS, IS 11171, IEC 76.
Quality
MUSKAAN’S products are certified for
ISO 9001 : 2000 by NABCB. MPIL has set up a
complete quality management system to offer
the best customer satisfaction.
Description
 MPIL
manufacture Ventilated Dry Type Transformer
are totally maintenance free and safe from
fire as material used are metals, ceramics,
fiberglass and resin It is environment
friendly as there is no oil, hence handing
becomes easier and there are no chances of
spillages and leakages and there is minimal
non toxic smoke in case of fire.
MPIL offers Ventilated Dry Type Transformers
with class H/E insulation which can bear
heat upto 180/220 degree C and can be used
in humid and chemically polluted atmosphere.
Winding
LV & HV Winding are done in dust free air
conditioned winding shops. Rectangular
copper strips are used for LV winding
insulated with Nomex while HV winding are of
copper wire insulated with Nomex or suitable
material for temperature rise if wrapping is
not possible due to small diameter.
Testing
All transformers are tested for routine
test. MPIL has in-house facilities for
conducting all routine tests as per IEC &
IS.
