Winding

Generally the H.V winding is of inter leaved and continuous winding to improve the perfermance under impulse voltage and obtain uniform distribution voltage. The pressboard spacers are rounded at the edges so as to improve insulation reliability oil flowing within the winding will be above to lower the coil temperature rise and hot-spot temperature thus ensuring a prolonged insulating service life.

Both the H.V and M.V. winding are generally provided with separate voltage regulating windings, so the ampere turns of all the windings are completely balanced. These can effctively eliminating the axial electrodynamics force during external short circuit and improve the dynamic stability under external short circuit.
