Product Description

Product Description:

ST-M-2500/12/0.46 is an efficient and reliable oil-immersed distribution transformer with a design capacity of 2500 kilovolt-amperes (kVA). It adopts advanced oil-immersed cooling technology to ensure excellent heat dissipation performance and long-term operation stability. Its high-voltage side rated voltage is 12 kilovolts (kV) and the low-voltage side rated voltage is 0.46 kilovolts (kV). It is designed to meet the core needs of safely and efficiently stepping down the medium-voltage grid power to low-voltage electrical equipment in the industrial, commercial and infrastructure fields. This transformer usually adopts a sturdy fully sealed structure, and the internal insulating oil works in an environment isolated from oxygen and moisture, which significantly delays aging and achieves maintenance-free operation. With its excellent electrical performance, rugged and durable design and good adaptability to harsh environments, it is a key equipment to ensure the continuity of power supply and power quality.
