R _______________________________________________________________WIRE IDENTIFICATION BY THE SUPPLIER - DESCRIPTION AND OPERATION
R R R R R R R R R R _______1. General This topic covers the identification and the markings made by the manufacturer during the manufacture of the wires and cables. Définitions : Conductor : The conductor is the conducting element of the cable formed from one or more strands. Core : Assembly of a conductor and insulation which then form part of a complete single or multiconductor cable. Cable or wire : A cable is an assembly consisting of a conductor, insulation and, where applicable, a sheath, screen or jacket.
__________________2. P/N Identification All the wire types (US and Metric) agree with Standards (ABS, ASNE, EN, NSA,...). The wires are identified as follows:
A. General case: ABSXXXX EXXXX NSAXXXXXX XX XX XX XXXXXX
--------- -- --
