Applications Directly buried or installed inducts for 600 volt secondary distribution. Construction Concentric stranded or compressed 1350-H19 aluminum conductors, crosslinked polyethylene insulation. Insulated conductors surface printed, neutral triple yellow striped. Two phase and one neutral conductor twisted together (LH lay) or parallel if so specified. Black neutrals may be specified if desired. Standards Secondary UD triplex conductor 600V cable meets or exceeds the following ASTM specifications. B-230 Aluminum Wire, 1350-H19 for Electrical Purposes. B-231 Aluminum 1350 conductors, Concentric-Lay-Stranded. B-786 "19 Wire combination unilay-stranded Aluminum Conductors for subsequent insulation". B-901 "Compressed round stranded Aluminum Conductors using single input wire construction". Secondary UD triplex conductor 600V cable meets or exceeds all applicable requirements of ICEA S-105-692. "USE-2" per UL 854 available upon request. Options Cable in Duct (CIC) Abrasion Resistant Ampacity 90oC conductor temperature, 20oC ambient, RHO 50, 100% load factor for three conductor triplex with neutral carrying only unbalanced load. Technical data for cable with solid black neutral is identical to yellow extruded stripe data. All yellow extruded stripe cable is XLP insulation. To determine correct ampacity by conductor size, please consult the National Electric Code, latest edition.
