Stress Cone Location
Stress Cone Location
(OP)
On a 5 kv system installation using shielded cable, do the stress cones have to be at the end of the conductors next to the cable lugs or can they be located 2 to 3 feet back from the cable lugs?
This added distance would allow someone to replace a cable lug without having to re-do the stress cone installation.
If the answer is "yes", can this also be done to 15 kV cable installations?

Dave

If you don't do that, then localized electrical stresses will start problems, evidenced by ozone production, corona, etc.

Thanks to both of you for your information and advice.

limit of the shield.
"if the clearance between Ph/Ph or Ph/Grd cannot be maintained in the cross over area Raychem's conductive tubing can be used.
Clearance then only need to be maintained above the end of the conductive tubing" [Raychem's remark]
