S11-M.ZT On-load Tap Changed (OLTC) Power Transformer with adjustable capacit
Product Description
These transformers are designed and developed using latest technologies and can be provided with a variety of terminations so as to suit the requirements for new installation or replacement.
Optimum efficiency is ensured by delicate proportioning of core and winding looses Electrolytic Grade pure copper, with Transposition in L.V. coil for current sharing in parallel Conductors, Electric grade press paper, boards and mineral oil. Thus better regulation is achieved resulting in longer life. Careful designing also reduces noise level to the minimum.
