How much room do I need for stress cone terminations?
I have 5kV gear that was modified for top entry by adding a 12” deep rear extension. Now that I have the busses there and facing upwards, I am wondering if that is enough space for stress cone terminations since the cables coming in are shielded or if I need to have a “top-hat” added to the gear. I have 12-750kcmil (MCM) copper conductors (4 per phase).
Are you talking about stress cones or termination kits? We have been using cold-shrink termination kits with stress control already built-in. Check out the 3M web site, the popular brand is QT-III if I remember right. They have dimensions right on the cut sheets based on your application.
