110 kV shunt capacitor with double tower structure has wide application. However

its economy performance is weaker due to its relatively larger land occupation area. The construction of UHV project has developed towards compact and integrated direction

the use of 110 kV shunt capacitor with single tower structure can reduce the land area effectively

save cost

has active significance and good development and application prospect. In this paper

according to the basic parameters at 110 kV side of 1 000 kV UHV AC transmission project

the design proposal of 110 kV shunt capacitorwith single tower structure is proposed. The design analysis

calculation and test verification for each technical performance of the capacitor are made. It is shown by the result that 110 kV shunt capacitor with single tower structure has good economic and technical performance and possesses engineering application conditions.
