Product Description
220KV Power transformers can be constructed as two windings, or three windings,
These oil immersed type transformers are the outdoor use, key equipment from HV distribution line to LV feeders.
Till now we have developed several grades of these transformer to achieve better green requirement of energy saving and environment protection: S9 series, S11 series, S13 series and etc, the main difference is that the cold rolled grain oriented steel sheet can realize smaller no load loss.
Generally the normal working condition required: -25 ~ 45 degree, altitude not more than 1000m, if some necessary parts changed, the transformer can run in more ultimate conditions: I. E. -45~50 degree, or 2000m altitude and etc.
