Abstract
Rigid jumper is the most complex part of transmission line construction,and its corona is more severe than common fittings,especially for the UHV rigid jumper.It is necessary to test different kinds of rigid jumper.This paper described two forms of rigid jumpers,i.e.tube-type and cage-type rigid jumpers,and their visible corona tests were conducted,respectively.By comparing the tests,the weak link of the rigid jumpers was analyzed,which may offer an evidence for the design of UHV rigid jumpers.
