220kV double split transformer

In order to solve the problem of large-scale super capacity centralized power generation of new energy power stations, double split structure is adopted. Each phase of a double-split transformer consists of a high-voltage winding and two low-voltage winding with the same voltage and capacity. The double split transformer normally transmits electrical energy between the high and low voltage windings. Two low-voltage windings of the same voltage and capacity can be operated separately or in parallel to bear different loads. Mainly used in wind power, photovoltaic and other new energy power generation markets and large state-owned enterprises.

10kV distribution transformer
