Type MC-HL Armored Class 1 Instrumentation Cable

Multiple Shielded Pairs or Triads – Individual and Overall Shield

600 Volts 90°C Rating

 

Specifications

Conductors: Bare soft annealed copper, Class B, 7-strand concentric per ASTM B-8.

Insulation: Flame-retardant Okoseal (PVC) per UL 83, 15 mils nominal thickness, 90°C temperature rating.

Jacket: Nylon per UL 83, 4 mils nominal thickness.

Conductor Identification: Pigmented black and white in pairs; black, white and red in triads.

Assembly: Pairs or triads assembled with left-hand lay. Non-wicking fillers included where required to provide a round cable.

Cable Shield: Aluminum/Polyester tape overlapped to provide 100% coverage, and a 7-strand tinned copper drain wire, same size as conductor.

Inner Jacket: Black, flame-retardant Okoseal per UL Standard 1569. A rip cord is laid longitudinally under the jacket to facilitate removal.

C-L-X Sheath: A close-fitting, impervious, continuously welded and corrugated, aluminum sheath meeting UL 1569 provides complete protection against moisture, liquids, and gases, has excellent mechanical strength, and provides equipment grounding through the sheath.

Outer Jacket: Black, flame-retardant Okoseal per UL Standard 1569.

Classifications: UL Listed as Type MC-HL Articles 501, 502, 503, 504 and 505 of the National Electrical Code.

Applications

Okonite C-L-X Single pair or triad type P-OS instrumentation cables are designed for use on Class 1 Remote-Control Signaling circuits or where a 600V cable is desired, as instrumentation, process control, or computer cable transmitting signals at levels above 100 milli-volts in circuits where shielding against external interference is required, but shielding against interference among groups is not required. For use indoors or outdoors; wet or dry locations; in cable trays; in raceways; supported by a messenger wire; for direct burial; in Classes I, II, and III, Divisions 1 and 2 hazardous locations per NEC Articles 501, 502, 503, 504 and 505. Listed by American Bureau of Shipping (ABS) as CWCMC-MC-HL and by UL as marine Shipboard. Also for use as non power limited fire protective signaling cable (NPLF) per NEC Code 760. The overall shield eliminates most of the static interference from the electric field radiated by power cables and other electrical equipment. The C-L-X sheath provides the physical protection against mechanical damage as required in NEC Section 725-8 as well as complete protection against moisture or gases entering the cable.  For dc service in wet locations, X-Olene insulation is recommended. These cables also comply with UL requirements for Types CL2 and CL3.
