These arresters are designed for 10,000 feet. ncrease clearances "S" and "T" 3% for each feet over 6000 feet. 2. When installed, exhaust ports should be directed away from adjacent apparatus. Ratings above 312 KV do not have directional venting. 3. Arrester assembly consists of arrester unit, line terminal assembly, ground terminal bracket, grading ring (if required), all hardware (excluding base mounting hardware). master nameplate, and line and ground connectors.. Arrester assemblies made up of more than one unit do not have interchangeable units. 5. Add 6.00 inches to "" dimension when using an insulating post. Add inches to "" dimension when using an insulating base for ratings 60-68KV, and 1.75 inches for ratings 3-8KV. 6. Line and ground clamp type connectors suitable for copper or aluminum conductors with diameter of 0.25 to 0.75 inches. Line terminal connectors accomodate conductors with diameter of inches on porcelain top arresters. ndoor-outdoor Altitude 0-1 0,000 feet 2-68 KV Porcelain Top 3-2 KV See Enlarged V1ew of Term1nal ( Deta11 "A") Figure l ( O.D. 5057A93) Mounting Dimensions ( 3 Phase nstallation Layout) 1--- s ----<-> (See Mounting D1mens1onsl Mounting ole for.500 Diameter Bolts --7-T-T---:?'t (Thickness of Lug on Casting.750) Style Kv Rating 5556A60A A60A0 5556A60A A60A A60A A60A A60A A60A A60A A60A2 2.5 ]-imesions (nches),, i F WE A Page 1 Station Arrester Type CPL Controlled Protective Level Detaii " A " s it Creep ' L1ne Term 1na Coble S1ze#2to 350MCM,.255 to.681 nch D1ameter lr, Weight (Lbs.)
