For self-contained and pipe type cable systems. High voltage ATA/ATL type terminations are designed for single conductor, low and high pressure fluid and gas filled cables on transmission systems rated 69 through 800kV. Terminations are available for indoor, outdoor and equipment applications including horizontal or inverted mounted. For equipment installations the terminations are immersed in fluid.
Type ATA-N terminations are used to terminate high pressure fluid or gas filled cables. Conventional stress control designs are applicable up to 161kV on cables with nominal pressure ratings of 200 psi and higher. Type ATL-N terminations are used for low pressure, self-contained, fluid filled cables. Conventional stress control designs are applicable up to 161kV for maximum conductor sizes through 3000 kcmil (1500mm2) with nominal pressure ratings of 15 psi and higher. Capacitor graded stress control designs are available for both ATA and ATL style terminations for 230 through 800kV liquid impregnated cables with a 3000 kcmil (1500mm2) maximum conductor size.
Catalog number includes porcelain termination, connector, aerial lug, stress cone and paper roll assembly kit, top corona shield, inner stress control porcelain (for oil filled only), stainless steel body/flange (copper for ATL) and base plate, check-plate and pipe stub assembly (for ATA). Options include valves, high strength designs (up to 400 psi nominal), connectors for aluminum cable, diffusion chambers, and base plate insulators.
