Rating105 deg C, 300 Vac, Cable Flame, Oil Res. 60 or 80C, Gas & Moisture Res. 75C.
Conductor26 AWG - 18 AWG, Solid or Stranded Round.
InsulationLabeled or complying with manufacturer's AWM procedure.
AssemblyTwo or more individually insulated conductors or groups of insulated conductors cabled together. All conductors in any group twisted together. If more than one group is used, all groups shall also be twisted together. The length of lay of the twisted conductors or groups is not specified. Fillers may be used in a cable but are not required. A barrier layer, if employed, may be a fibrous wrap serving, or braid; paper; nylon; oriented polyethylene terephthalate; or a thermoplastic-tape wrap. Such a barrier layer would serve to protect the cable during further processing and would be applied immediately over the twisted assembly of individual conductors or groups of conductors.
