Hi Lance

We had this problem a number of years ago on what we term “22kv Bullhorn Carriers” with the first solution being to temp install hangers made from bent earthing rod and then hang the earth underneath but as this in not a clamped connection it is not suitable to carry any fault current. Now we use “Cut Out Earth Clamps” from Transnet installed with a shotgun or insulated stick. Further moving the earths away from the top live side and creating a clamped connection.

Before this guys were hanging the earths directly on the lower carrier hanging point encroaching on the minimum gap to the top live side and also bending the lower hanger of the carrier.

I hope this relates to the question asked.

Cheers
