Applications
- Armored Medium-Voltage power cables offer an economical, rugged and reliable alternative to labor-intensive cable in conduit wiring methods
- Installed on metal racks, troughs, in raceways, in cable trays or secured to supports spaced not more than six feet apart
- Installed in both exposed and concealed work, wet or dry locations, directly buried or embedded in concrete
Construction
Conductor: Class A or B Compressed concentric stranded aluminum alloy 1350 per ASTM B 231. Stranded conductors are water-blocked with conductor filling compound.
Conductor Shield: Extruded thermosetting semiconducting shield which is free stripping from the conductor and bonded to the insulation
Insulation: Extruded, unfilled Tree-Retardant Cross-linked Polyethylene (TRXLPE) as defined in ANSI/ICEA S-94-649
Insulation Shield: Extruded thermosetting semiconducting shield with controlled adhesion to the insulation providing the required balance between electrical integrity and ease of stripping.
Metallic Shield: The metallic shield is flat uncoated 5-mil thick copper tape helically applied with minimum 20% overlap
Ground Wire: Three bare copper ground wires placed at the interstice of the conductor.
Fillers: Non hygroscopic fillers, forming a firm and cylindrical cable core.
Binder Tape: A binder tape is applied to maintain core symmetry and mechanical stability.
Armor: Aluminum Interlocked Armor applied over the binder tape of the cable core
Jacket: Black, sunlight resistant, flame retardant PVC jacket

NOTES:
- The above dimensions are approximate and subject to normal manufacturing tolerances.
- Ampacities are based on the following: Three Phase Operation In Duct (2011 NEC Table 310.60(C)(80): Three-conductor cable in plastic duct, direct-buried, 105°C conductor temperature, 20°C ambient temperature, earth RHO of 90°C-cm/Watt, and 100% load factor, and shields short-circuited. Isolated in Air (2011 NEC Table 310.60(C)(72)): Three-conductor cable, 105°C conductor temperature, and 40°C ambient temperature, and shields grounded at one point only. In Cable Tray: per 2011 NEC 392.80(B)(1)(b)3, for single conductor cables, sizes 1/0 7m视频 and larger, installed in a single layer in an uncovered table tray, with a maintained space of not less than one cable diameter between individual conductors, the ampacities shall not exceed the allowable ampacities stated in 2011 NEC Table 310.60(C)(72) (Aluminum), “Isolated in Air” values noted above.
- Insulated cables are capable of operating at 105°C. However, the maximum operating temperature of the cable should be based on the maximum operating temperature of the cable accessories to be used.
