Types WGSTH and WGSTE ground studs are designed for corona-free service at 345 KV and 500 KV respectively. The contact stud is solid aluminum rod, welded into saddle and bell or sphere castings. Because of the damping effect created by the extended sphere, it is recommended that 500 KV grounding studs be installed as near to a bus support as practical.
