Open Ventilated Dry Type (OVDT) Vacuum Pressure Impregnated (VPI) Eco Friendly Transformers

KOTSONS was one of the first Indian manufacturer to use the DuPont ReliatraN® branded solution and develop Ventilated Dry Type Transformers in collaboration with E. I. du Pont de Nemours and Company, U.S.A.
KOTSONS Eco Friendly VP transformer coils are vacuum pressure impregnated in high temperature varnish. The process includes complete submersion in varnish under vacuum and pressure and regulated curing using PLC controlled equipment to ensure consistency. The finished coils are effectively protected against moisture, dirt, and most industrial contaminants. A 220°C Class NOMEX® Listed insulation system is used on KOTSONS OVDT VPI transformers regardless of specified temperature rating. This system accommodates a standard temperature rise of 155°C. Optional temperature rises of 90°C and 115°C and fan cooling allow for unsurpassed overload capacity.
Salient Features & Advantages of OVDT VPI Dry Transformers:

1. Excellent mechanical and short-circuit strength due to the VPI Process
2. No danger of fire or explosion. No liquids to leak hence no flammable liquid & no oil pollution
3. Less weight than comparable cast resin units
4. Low total ownership costs and low initial costs
5. Use of NOMEX® UL® Certified Insulation Materials, listed 220°C insulation system, regardless of temperature rating
6. VPI transformers are non-explosive with high resistance to flame and do not require vaults, containment dikes, or expensive fire suppression systems
7. Low Partial Discharge - VPI process ensures void free insulation system
8. Moisture Ingress Resistant & Immune to polluted atmosphere
9. Easy to repair (open coils) due to OVDT Design
10. Eco Friendly, No harm to environment at the end of Life

Company Details

KPL (KOTSONS Pvt. Ltd.) established its transformer manufacturing unit back in 1979 at Alwar, India to produce distribution & power transformers of 33 KV class voltage, to meet the needs of public utilities organizations and of private industrial sectors in India. It was KPL’s vision of becoming integrated global transformer manufacturing company that the company's manufacturing facilities were later expanded and second & third plant was setup at Agra (U.P) and Bazpur (Uttaranchal), India and product range was expanded up to 25 MVA with 33 KV class, to cater the needs of international demands.
Today, with over more than three & half decades of experience in the manufacturing, KPL has grown in geographical reach, market size and product range to become one of the leading transformer manufacturing company. Our products comprehensively fulfilled the requirements of local and international standard specifications and their stringent requirements.
KPL has ISO 9001:2008, ISO 14001:2004 & OHSAS 18001:2007 certification from DNV-GL, THE NETHERLANDS and commits itself to introduce and maintain a quality system that ensures quality products and services to total satisfaction of the customer. The quality control department controls and monitor all quality control documents and carries out its inspection at all strategic points in the production process. TQM (Total Quality Management) programme is in place, which is backed by strong in house R&D and a crew of service engineers for providing after sales services.
At transformer's quality & soundness point, KPL's transformers upto 1600 kVA are type tested for temperature rise test, impulse test and short circuit test at world's renowned testing laboratory KEMA, THE NETHERLANDS.
At KPL, R&D is a continuous process and department has consistently produced innovative concepts that have now become industry standards.
A highly qualified and experienced technical personnel keeps an eye upon the latest development in technology and the product to supply a prime quality product at competitive price.
KPL has in house facilities for conducting all routine tests as per IEC, DIN, BS, ANSI, SABS, BIS, CENELEC, GOST, NEMA & IS and temperature rise type test.
New Era : Transformers to grab Green Energy
