Flexible cable vs flexible braid transformer connection


Senior Member
What is the preferred method for Close coupled Equipment connections on the HV and LV side of a liquid filled transformer?

For example if I have a 15kv switch being close coupled to the HV side of a transformer is it prefered to have flexible cable between switch and transformer bushing or connect via bus with flexible braid between transformer and bushing?

Any downside to using an adequately rated flexible for such connections?
