4.1.4.2 Fillers
If fillers are used, they shall be of suitable material and shall be twisted with the individual conductors to form a compact assembly having an essentially circular cross-section.
4.1.4.3 Binder
The application of a binder, consisting of a braid, tape, or wrap of suitable material over the conductor assembly. shall be permitted.
4.1.5 Shielding
4.1.5.1 A shield shall be permitted over one or more of the circuit conductors or over the entire assembly under the jacket.
4.1.5.2 The shield shall be a braid of copper wires, copper wire wrapped shields, a metallized polyester tape with a drain wire, or a metal tape with or without a drain wire.
4.1.5.3 A braided or wrapped shield shall be composed of 0.013 mm2 or 0.020 mm2 (36 AWG or 34 AWG) copper wires for flexible cords with conductors of 5.26 mm2 (10 AWG) and smaller, and of 0.032 mm2 or 0.051 mm2 (32 AWG or 30 AWG) copper wires for flexible cords with conductors larger than 5.26 mm2 (10 AWG). If the shield wires and contacting compounds have been shown to be mutually compatible in accordance with Clause 5.2.8, bare copper wires shall be permitted. Otherwise, if a separator is not provided, all the individual wires of the shield shall be separately tinned. The braided or wrapped shield shall provide a minimum coverage of 85 percent when calculated in accordance with the test. Calculation of Coverage of Shielding — Annex G, in CANJCSA C22.2 No. 2556, UL 2556, NMX-J-556-ANCE.
4.1.5.4 A laminated tape of polyester film and aluminum foil shall be applied longitudinally or helically so that it has at least a 1.52 mm (0.060 in) overlap. The total thickness of the tape shall be 0.038 mm (0.0015 In) minimum for flexible cords with conductors 6.63 mm2 (9 AWG) and smaller and 0.0635 mm (0.0025 in) for flexible cords with conductors 8.37 mm2 (8 AWG) arid larger. The minimum size of drain wire shall be 0.325 mm2 (22 AWG) seven-strand minimum tinned copper for flexible cords with conductors 2.63 mm2 (13 AWG) and smaller, 0.519 mm2 (20 AWG) seven-strand minimum tinned copper for flexible cords with conductors of 3.31 mm2 to 663 mm2 (12 — 9 AWG), and 0.824 mm2 (18 AWG) seven-strand minimum tinned copper for flexible cords with conductors of 8.37 mm2 (8 AWG) and larger. The drain wire shall be in contact with the aluminum.
4.1.5.5 The overall diameters of shielded cords shall comply with the overall diameters in Table 13, plus the additional increase due to the shield.
4.1.5.6 Flexible cords and cables employing shields of different materials or constructions than those described in Clauses 4.1.5.3 and 4.1.5.4 shall be examined and tested in accordance with Clause 5.2.9.UL 62-2018 pdf free download.
