EHV WELDED COUPLERS FOR TUBE TYPE WCI

ALUMINUM WCI

Aluminum alloy weldment couplers are designed for corona free service at 345, 500, and 765 KV levels. Slot provides for close fit regardless of tubing tolerance. The joint can be stiffened, if desired, by drilling four holes in the tubing at 90˚ lateral points and plug welding the tubing to the coupler. When joining two different bus sizes, add “EHV” suffix to catalog number (example: WCI-5040-EHV, for coupling a 5” IPS to a 4” IPS). Material: Castings - 356-T6 aluminum alloy Note: To specify coupler for extra heavy (Schedule 80, EHIPS) tubing add “H” to catalog number; example: WCIH-3030.
