Con. Multiple-cond. THWN / THHN

600 V / 75 °C

General description

Cable with two or more soft drawn copper conductors with Polyvinyl Chloride (PVC) Thermoplastic Individual Insulation and a polyamide (nylon), overcoat, identified by color coding (See Table 1), fillers, binder tape and overall Polyvinyl Chloride (PVC) thermoplastic jacket.


  • Viakons Control / Multiple-conductor cables THWN/THHN meet the following specifications:
  • NOM-063-SCFI Electric products- conductors - safety requirements.
  • NMX-J-010-ANCE Conductors with polyvinyl chloride thermoplastic insulation rated to 600 V.

Main applications

  • Designed to feed control circuits in industrial plants and to connect safety equipment and signaling devices, where no-fire propagation characteristics are required.
  • Can be installed in trays or conduits and in underground or exposed to sunlight facilities, in wet or dry places.
  • Petrochemical Industry applications.


  • Maximum operation voltage: 600 V.
  • Maximum operation temperature of the conductor:
  • 75°C In a wet environment.
  • 90°C In a dry environment.
  • Soft drawn concentric lay stranded copper conductor.
  • Manufactured in sizes from 2,082 to 5,26 mm2 (14 to 10 AWG).
  • No-fire propagation characteristics.
  • Black outer jacket.


  • Due to the nylon overcoat, they are highly resistant to abrasion, oil, and chemical agents.
  • Meet or exceed the no-fire propagation test (NMX-J-093).
  • Smaller overall diameter and lighter total weight than control cables-LS and control/multiple-conductor cables THW- LS/THHW-LS.
