Applications
Nexans 600 V Ultrex VN Tray Cables are listed as type TC / TC-ER under UL 1277 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 three 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 THHN/THWN-2 per UL 83 for sizes 14 AWG to 500 kcmil and type TFN per UL 66 for 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.
Sample print legend:
NEXANS-C ULTREX-VN 600V TC-ER 3/C-12 AWG THHN/THWN-2 SUN RES DIR BUR (UL) ROHS (mm/dd/yyyy)
Conductor Identification:
18 AWG to 10 AWG: color coded per Method #1-E2 per ICEA S-73-532
8 AWG to 500 kcmil: black with number coding per Method 4 to ICEA S-73-532
