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).
StandardsThe Dry Type transformer are manufactured to comply with National International Standards BIS, IS 11171, IEC
QualityMUSKAAN'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.
DescriptionMPIL
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.
WindingLV &
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.
TestingAll
transformers are tested for
routine test. MPIL has in-house
facilities for conducting all
routine tests as per IEC & IS.

Aspects
- Transformers insulated with
Nomex brand materials are
extremely safe, even when
exposed to fire
-
High flame resistance, & low
smoke and no toxic
off-gasses
-
Class H & E ventilated dry
type transformers can be
built smaller, reducing the
footprint to the
environment, conserving
space
-
Insulation is friendly to
use during manufacturing-no
skin irritants or surface
chemicals
