Applications
Nexans 600 V Ultrex VN Tray Cables are listed as type TC / TC-ER under UL 127 Electrical Power and Control Cables. These cables may be installed in wet or dry locations; in cable trays, raceways and open air; and are suitable for exposure to weather, direct burial and for Class I, Div. 2 (also Zone 2) and Class II, Div. 2 hazardous locations per NEC 2008 and NEC 2011. Cables with 3 or more conductors are UL listed for exposed runs (ER) when installed in accordance with NEC 2008 and NEC 2011 Article 336.10(7).
Construction
Conductor:
Bare, annealed copper conforming to ASTM B3 and Class B stranded in accordance to ASTM B8, from 18 AWG to 500 kcmil. Compressed copper for 14 AWG through 500 kcmil..
Insulation:
Flame-retardant PVC/Nylon type TFN per UL 66 for sizes 18 AWG and 16 AWG.
Assembly:
Non-shielded: cables with 3 or more conductors and cabled in concentric layers with interstices filled with suitable fillers, as required. Two-conductor cables are supplied in a flat/parallel configuration. Ground wires, are sized as required by UL 1277 (refer to applicable product tables for the standard sizes provided). Sizes 14 AWG to 6 AWG have an insulated green ground wire. Size 4 AWG and larger have a bare ground wire. Where necessary, a binder tape of synthetic material assembles the core in a tight circular configuration.
Shielded: cabled in concentric layers with interstices filled with suitable fillers as required. A helically wrapped aluminum tape, with synthetic backing, gives 100% shielding. A tinned copper drain wire is placed in contact with the aluminum side of the tape, to lower the resistance and to assist in the termination of the shield.
Jacket:
UL listed sunlight and moisture resistant, sequentially marked, black, flame retardant polyvinyl chloride (PVC) material meeting the requirements of UL 1277. A Nylon ripcord is included for ease of jacket removal. Jacket surface is printed with required UL / NEC code information and sequential footage markings.
