Construction:

  1. Conductor: 8 - 4/0 AWG: Class K, Flexible stranded bare copper. 250 - 750 kcmil: Class I, Flexible stranded bare copper
  2. Insulation: Polyvinyl Chloride (PVC) with Nylon sheath

Applications and Features:

Southwire’s MachineFLEX™ Power cables are suited for use in wet and dry areas, conduits, ducts, troughs, trays, aerial supported by a messenger, and where superior electrical properties are desired. These cables are capable of operating continuously at the conductor temperature not in excess of 90°C for normal operation in wet and dry locations, 130°C for emergency overload, and 150°C for short circuit conditions. 1/0 AWG & Larger rated for CT use.
