Style 20237 Multiple Conductor with Extruded Non-integral Jacket.

Rating125 deg C, 300 Vac, Cable flame.
Conductor36 AWG min. Solid or Stranded.
InsulationLabeled or complying with manufacturer's AWM Procedure. The designations of all styles of individual conductors used in making up the cable assembly shall be available.
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.
ShieldOptional.
CoveringOptional - 4 mil or heavier wall of PVC or other thermoplastic covering may be extruded over the conductor assembly or groups of conductors (with or without shields).
