The design of the oil immersed power transformer

The design of the oil immersed power transformer, windings can be continuous or interleaved disc, simple or multiple helix. Cooling channels are made with duly shaped rods and flow guide rings. Tappings are provided on the HV windings, controlled either by means of an off circuit switch or an on load tap changer transformer.In addition to power and distribution transformer manufacturer，power transformers either for general purposes (reducing-increasing voltage on main grid, feeding auxiliary transformers, transferring to the grid the own produced current) and for specific purposes (industrial transformers, autotransformers, insulation transformers, starting transformers, transformers for testing ..).
