INTRODUCTION DEEPARTI SILICONS 133-A, SECTOR –A, INDUSTRIAL AREA, MANDIDEEP Telephone: , mob. No :- 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 in- house 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 Features Type :- Outdoor/indoor Related voltage : - up to 33kV Primary current :- 5A to 2000A Secondary current :- 5A & 1A Ratio :- as per requirement Accuracy/Burden :- as per requirement Voltage factor :- 1.2 cont.& as per requirement
