ALUMINUM HVETF/EVETF

Aluminum alloy, tube to flat, expansion terminals are designed for corona free service at 345 and 500 KV respectively. This design provides ±2 inch expansion. Terminals with side formed contact may be ordered by adding “SF” to the catalog number (example: HVETF-40-D-SF). For additional equipment clearance, a pad extension may be ordered by adding “E” in the catalog number (example: HVETFE-40-D). When pad extension is specified, one hardware shield and hardware is furnished. Specify “H” in catalog number if schedule 80 EHIPS tubing is to be used; example: HVETFH-40-D. Pad mounting hardware is not furnished as part of this catalog number and must be ordered separately, specifying thickness of pad to be clamped. Material: Castings – 356-T6 aluminum alloy Rings – 6061-T6 aluminum alloy Ring Brackets – 6061-T6 aluminum alloy Shunts – 1100-0 aluminum alloy Guide Mounting Hardware – galvanized steel Ring Mounting Hardware – aluminum alloy Refer to for installation chart DC-6750 on page 88 for instructions. Add suffix: “-HS” for one hardware shield, and “-HS2” for two hardware shields.
