110kV High Voltage Three Phase Two Winding NLTC Power Transformer

110kV Oil-immersed Power Transformers

At present, lines with voltage levels of 110kV and above are generally used as transmission lines, and lines with voltages of 35kV and below are used as distribution lines. 110kV transformers are mostly used in power supply systems to change 110kV transmission voltage into 35kV, 20kV or 10kV distribution voltage. , for use by users or public distribution transformers. Large power users also use 110kV transformers as user transformers. Small power plants also use 110kV as the grid-connected voltage, so a 110kV transformer is used as a step-up transformer.

The commonly used 110kV High Voltage Three Phase Two Winding NLTC Power Transformer capacity ranges from 10,000 to 63,000kVA, with 31,500kVA being the most common in power systems. The maximum capacity produced by our company is 100000kVA.
