Aluminum alloy weldment expansion stud connectors are the same as Type HVEDST/EVEDST listed on preceding pages, except they mount at 90° to the stud. Both are designed for corona free service at 345 and 500 KV respectively. Pressure plates are puddle-welded to straps on three (3) sides. Contact surfaces on pressure plates have bonded copper liners. Connector is designed for ± one inch expansion. Specify "H" in catalog number if schedule 80 EHIPS tubing is to be used; example: WSATHL. Spacing of corona rings is based on use over transformer expansion cap or dome of 17" diameter at 345 KV, or 22" diameter at 500 KV. Contact factory for information on other diameters.
