Oil Cooled Power and Distribution Transformers

Oil Cooled Power and Distribution Transformers Oil Cooled Power and Distribution Transformers
(With Off Circuit Tap Changer)
RANGE : Up to 15000KVA Class: Up to 33 KV


Runthala Industries covers a wide range of Oil Filled Power and Distribution Transformers with the Off Circuit Tap Changer conforming to the international standards of quality and safety. These transformers are designed and developed using the latest technology and provided with a variety of terminations so as to suit the requirements for any new installation or replacement.
Optimum efficiency is ensured by delicate proportioning of core and winding losses using CRGO M3 to M5 MOH Lamination, Electrolytic Grade copper with transposition in L.V. coil for current sharing in parallel conductors, electric grade press paper, boards and mineral oil. Thus a better regulation is achieved resulting in a longer life. Careful designing also reduces the noise level to the minimum.
