We are replacing stress cones on a 35kV system as a result of a recent cable fault. During the installation of the new cones it was sugessted to add heat shrink overlapping the the new stress cone covering the ground braid completely. In my experience I have never seen this done and I am a little concerned of any long term effect this may have on the new cones. Can anyone comment if this is common pratice or if there are any long term effects by doing so.

Stress Cone Ground Braids

We prefer to have the shield braid accessible for ease of testing the shield continuity / resistance. If a pig tail is not accessible and the stress cones are shrunk so that the cable are totally covered right down to the break out boots, then we have no provisions to determine the continuity of the shields during maintenance checks.
Cables may or may not be grounded be grounded at both ends and an accessible ground wire helps in doing shield checks but shield test is preferrable done tested at the braid at both ends to the conductor.
we have found broken shield just above the connector to the stress cones for installation where there was ample room between the connectors and the terminals/stress cone assembly.
