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 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.
