vijay vidyuth udyog was established in the year 1989 with the purpose of manufacturing high quality distribution transformers at competitive prices. our manufacturing unit is fully equipped with the latest machinery, testing facilities and well supported by competent and experienced engineers to handle manufacture of cast resin dry type and oil immersed distribution transformers starting from 15 kva to over 2500 kva. our extensive range of high quality distribution transformers also includes on load tap changers (o.l.t.c) with remote tap changer cubicle (r.t.c.c panel) and automatic voltage relay (a.v.r) and special application transformers continues to confirm its reputation for delivering an undeniable quality, reliability and highly affordable price since our inception.Besides this, special transformers like dry type or air cooled transformers, low loss transformers and special type transformers are also manufactured based on the customised specifications. Our strength lies in our upgraded technology and commitment towards supply of quality products. Our products have been type-tested by the c.p.r.i
(central power research institute) and adhere to the specified national and international quality norms.
Oil Cooled Transformers
Our range of Oil cooled transformers ranges from capacities of 15 KVA to over 2500 KVA and Voltage class of 11KV/22KV/33KV with first filling of oil as per I.S 335 and temperature rise as 50°C in Oil and 55°C in winding and suitable for outdoor execution. All the transformers are of ONAN type, naturally cooled, double wound, Core type and are manufactured with off circuit or On Load Tap Changer (OLTC) with Remote Tap Changer Cubicle panel (RTCC) and AVR. The transformers are painted with three coats of DA grey paint as per IS: 5/1978 and in general conform to I.S 2026/1977
Air Cooled Transformers(Dry Type)
Dry type transformers have found increased applications in providing distribution of electrical power for indoor applications. They are used in preference to oil-filled transformers by virtue of reduced fire hazards. Increased concern over potential flammability and explosion hazards associated with oil-filled transformers is one of the key reasons for design of Dry type transformers.
Our range of manufacturing Dry Type Transformers which starts from 25 KVA are designed, manufactured and tested as per I.S 2026 and I.S 11171. Dry Type Transformers are varnish-impregnated transformers designed to withstand temperature rise of 90°C in winding with class-F insulation. These Transformers are used only for indoor installations where safety plays a vital role. They are provided with Off Circuit links on HV side with taps in steps of 2.5%. All the Transformers are tested according to routine tests as per I.S 2026 / 11171. Special Tests can also be conducted on special request.
