Rating80 deg C, 600, 1000 Vac, Cable flame.
Insulated ConductorLabeled or complying with manufacturer's AWM Procedure.
AssemblyTwo or more individually insulated conductors or groups of insulated conductors cabled together to form a round cable. All conductors in any group twisted together. If more than one group is used, groups shall also be twisted together. The length of lay of the twisted conductors or groups is not specified. A barrier layer, if employed, may be extruded thermoplastic, a fibrous wrap serving, or braid; paper; nylon; oriented polyethylene terephthalate; or thermoplastic-tape wrap. Such a barrier 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. A flat or oval cable may also be constructed with not more than three rows of single conductors or groups of conductors. Fillers may be provided.
