Style 20235 Multiple-conductor cable using non-integral jacket

Rating80 deg C, voltage rating not specified, Cable flame.
Conductor36 AWG minimum, Solid or Stranded.
Insulated ConductorLabeled or complies with manufacturer's AWM Procedure.
AssemblyTwo or more individually insulated conductors or groups of insulated conductors cabled together to form a round cable. A flat or oval cable may also be constructed with not more than three rows of single conductors or groups of conductors. 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 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 or over the shield, if provided.
CoveringOptional. Extruded PVC, 4 mils or heavier wall, or other thermoplastic covering may be extruded over the conductor assembly or groups of conductors (with or without shields).
ShieldOptional.
