 We introduce ourselves as
manufacturers of CT windings,
CT, PT, and CT-PT Units indoor
& outdoor and are located at
Mandideep near Bhopal.
 We are very well versed in this
line and are more than 15 years
old, involved in the
manufacturer of Transformer
laminations, toroidal cores , ring
cores, cut core ,stepped
round/rectangular core, DG
cores etc., secondary winding of
cores for CT’s up to 400 kV, wall
shunt assembly for power
transformer tanks etc.
We have recently added a complete product range
for manufacture of CT, PT up to 33 kv (outdoor &
indoor) we are well equipped with all
manufacturing facility for CT/PT .We have inhouse set up for production of transformer
laminations, slitting line for manufacture toroidal
cores, winding of Toroidal cores, primary and
secondary winding of CT/ PT, heat treatment etc.
We have a full fledged set up of testing facility of
the highest accuracies .We have qualified / skilled
man power involved in manufacture, production,
quality assurance, testing of our product range.
Informatively, our CT/PT units have been type tested
with CPRI Bhopal. The relevant certificate will be
submitted.
We have been well accepted in terms of quality,
delivery, etc. by our customers including M/S BHEL,
M/S ABB LTD., M/S Siemens, and M/S. Areva among
others.
May we request you to consider us as a source to
meet your Transformer Laminations, Toroidal cores,
Ring Core, Secondary windings, CT/PT requirement
and forward your valued enquiry enabling us to
initiate the process for business development.
Product
We offer comprehensive range of industrial products these are cost efficient, highly
durable and have long service life. Any tailor-made specification in the product can be
incorporated based on customer’s requirements. Our industrial products are:•
CT-PT COMBINED UNIT :- combined CT-PT units up to 33kV , this is a
system having 3 nos. Of CT’s& PT’s housed in
metallic enclosure live and earth parts are
insulated by porcelain insulators. This unit
used for 3 phase 4 wire system.
These units are hermetically sealed to
ensure non ageing of insulation.
•
CURRENT TRANSFORMER:- It is a measuring device for metering and
protection system.
•
POTENTIAL TRANSFORMER:- PT is used to step down the system voltage
to Measureable voltage of 110/63.5 V
