750 kV shunt reactor is a key device in the Northwest 750 kV backbone power transmission network under construction in China.For the purpose to develop a 750 kV shunt reactor with high performance and reliability

many transformer manufacturers in China have made researches on the key technologies for 750 kV shunt reactor

such as dielectric structure

vibration and noise reduction

prevention of local overheat

etc.

according to the requirements for the Northwest 750 kV Backbone Power Transmission Network.Progress has been achieved in the design and manufacture through calculation analysis and testing study.750 kV shunt reactors have been developed with partial discharge less than 100 pC

vibration less than 60 μm

noise less than 75 dB（A）

and without local overheat.Their main performance indexes reach the advanced international levels of the same type products.The 750 kV shunt reactors have been put into operation in the transmission network with satisfied operation.
