General
　　The type of oil-immersed power transformers is one of the main type in our company. It is the only core enterprise in Shandong to produce up to 220kV power transformers planned by original Ministry of Machine-Building Industry. The voltage level is from 6kV to 220kV; power rating is from 30KVA to 360000KVA; totally 23 series, 200 odd varieties, more than 1400 specification, meet all technical requirements of national Standard and the Standard of IEC.
Specifications
 
Note：
 1.The other transformers in difference rating can also be produced according to customers' requirements.
    2.Voltage and impedance can be provided according to customers' actural requirement.
    3.The outside dimensions in lists are only for reference. The final dimensions should be ratified after signing the contract and confirming the drawing.
