Power Transformer 30mva 69kv/115kv/230kv

A power transformer is a mere classification of transformers with a voltage range varying between 33 kV-400 kV and a rating above 200 MVA. The voltage ratings of power transformers available in the market include 400 kV, 200 kV, 110 kV, 66 kV, and 33 kV. The other types of transformers include distribution (230 V-11kV) and instrument transformers.

power supply transformer

Power transformers are a core component of power transmission system. The substation transformer used for power transmission and transformation in a unit or substation, and is also the core part of the substation. Transformers are the core equipment of the traction power supply system of electric locomotives, and also the key equipment to ensure the safe and stable operation of the traction power supply system.
