Description: Oil Cooled Distributed Transformer is built as per IS2026, BS171, IEC76, and other relevant standards. It generates low noise and consumes very less power. It is designed to render a trouble free performance and to withstand impulses, thermal and dynamic stresses. It is featured with magnetic circuit - lamination CRGO M3 to M5,MOH and ZDKH type; electric circuit - electrolytic grade 99.9% pure copper with transposition in L.V coil for current sharing in parallel conductors; dielectric circuits - electric grade press paper, boards and mineral oil; thermal circuit - ONAN through natural convection for effective cooling through axial and radial ducts. Its specifications include the following: 3 phase, 50 Hz in voltage of 11kV,22kV and 33kV; Off-circuit tap changer to provide +5% to -10% taps in steps of 2.5%; On-load tap changer to provide +7 to -21% instep of 1.75% tapping or as per customer requirement; class A insulated; vector group dyn 11 and continuous duty. The standard fittings include the following rating & diagram plate, earthing terminals, lifting jugs, thermometer pocket, off-circuit tap switch, air release hole with plug, and pressure relief valve.
