Power TransformerPower 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.  Product DescriptionDesign and Manufacture Standard ANSI-IEEE 57. 12/CSA/EN/BS/GOST/AS,IEC 600761  DesignSealed-tank system /Inert-gas pressure system or Conservator-tank system without diaphragmOn load or no load voltage tap changer ONAN/ONAF/ODAF/OFAF/OFWF/KNAN/KNAF Insulation Mineral Oil Inhibited I Not Inhibited I Vegetable oil Primary voltage Up to 230kv, up to 900kv BIL Capacity Up to 240MVA Frequency 50/60 HZOperating ConditionSuitable for indoor and outdoor application.
