Interconnecting two tublar buses
Interconnecting two tublar buses
(OP)
I have a situation where a 69KV transmission substation with 3 inch tubular aluminum bus is welded to 69KV Generating Station (rated at 75 MW) bus with 2 inch tubular bus as shown in the attached picture. Does this provide a good connection? If not then what is best solution to connect two stations with different pipe sizes. Please note the two stations are new. Any suggestion will be highly appreciated.

I don't know which company manufactures it, but I've seen what essentially looks like two clamps back to back bonded to each other with braided cross-link flex webbing. The clamps have cylindrical bores to match the OD of the tubular buswork, and provided all faces are well burnished beforehand and a non-ox compound is applied inside the joint, no welding is required for their installation.
