[pdf] [/pdf] [short] 477 Syringa All Aluminum Conductor AAC Allowable Ampacity for 477 Syringa All Aluminum Conductor AAC: 639 Amps Applications: AAC, or All Aluminum Conductor, is an electrical cable mainly used for distribution services as well as overhead transmission in outdoor premises due to the high-quality water-resistant aluminum conductor. The AAC cable can be of two classes: class AA cables are with bare conductors to be used in overhead lines, and class A is for an electrical wire with both bare conductors for increased flexibility and conductors with a weather-resistant cover. Also Known As: 477 syringa all aluminum conductor, 477 syringa all aluminum conductor table, 477 syringa aac all aluminum conductor, 477 syringa aac cable, 477 syringa aluminum alloy cable, 477 syringa abrasive resistant cable, 477 syringa transmission overhead, 477 syringa overhead power line components Standards: 1350-H19 for Electrical Purposes Concentric-Lay-Stranded Aluminum 1350 conductors Requirements of the National Electrical Code ASTM B-230 & B-23 Construction Conductors: AAC cable has a concentric lay stranded conductor consisting of Aluminum Alloy 1350-H19 wires and is available in both single-layer and multi-layer constructions. Note: AAC ampacity is based on 75ºC conductor temperature, 25 ºC ambient, 2ft1s wind, 961 watts/sq. foot sun, 0.5 coefficients of emissivity and absorption. Specifications: Conductor Size: 477 Stranding: 37 Class: A Diameter Inches: Indiv. Wire: 0.1135 Diameter Inches: O.D: 0.795 Cross Sectional Area (sq. inches): 0.3746 Approx. Weight lb/1000FT: 447.8 Approx. Rated Strength (lbs.): 8,690 Ampacity: 639 Amps [/short] Application: AAAC – All Aluminum Alloy Conductor is used for primarily and secondary overhead transmission and distributionservices. AAAC conductor is designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio and better sag characteristic. AAAC conductor has a higher resistance to corrosion than ACSR. Conductors: AAAC conductor is a concentric lay stranded conductor consisting of Aluminum Alloy 6201-T81 wires, similar in appearance to a 1350 grade aluminum conductor. Notes: DC resistance at 20°C of the 6201-T81 alloy has a greater resistance to abrasion than conductors of 1350-H19 grade aluminum. Standards: ASTM B-398 & B-399 Requirements of the National Electrical Code Show more
