Specifications
Conductors: Solid alloys per ANSI MC 96.1.
Insulation: Flame-retardant Okoseal (PVC) per UL Standards 13 and
2250, 15 mils nominal thickness, 105°C
temperature rating.
Conductor Identification: Pigmented insulation on individual
conductors negative conductor numerically printed for group
identification.
Communications Wire: 22 AWG, solid, bare copper conductor, 12 mils
nominal flame-retardant Okoseal insulation, 105C temperature rating.
Assembly: Pairs assembled with left-hand lay. Flame-retardant,
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 the
conductor.
Inner Jacket: Color-coded, flame-retardant Okoseal per UL Standards
13 and 2250. 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 provides complete protection against moisture,
liquids, and gases, has excellent mechanical strength, and provides
equipment grounding through the sheath.
Outer Jacket: Color-coded, flame-retardant Okoseal per UL Standards
13 and 2250.
Classifications: UL Listed as Type ITC/PLTC - Instrumentation Tray
Cable/Power Limited Tray Cable for use in accordance with Article 725 and
727 of the National Electrical Code.
The cables comply with UL 2250 and UL 13 for CL2 and CL3.
Applications
Okonite Type C-L-X P-OS (Pair/triad - Overall Shield)
Thermocouple Extension cables are designed for use as instrumentation and
process control cables in ITC non-classified or labeled circuits up to 150
volts and 5 amps (750VA) and in Class 2 or 3 Power-Limited circuits where
shielding against external interference is required, but shielding against
interference among groups is not required; indoors or outdoors; in wet or
dry locations with conductor operating temperatures up to 105°C;
in cable trays; in raceways; supported by a messenger wire; under raised
floors; for direct burial. Suitable Class I, Division 2, Class II,
Division 2, or Class III, Division 2 and Class I, Zone 2 hazardous locations. Also for use as
Power-Limited fire protective signaling cable (FPL) per NEC Code 760. The
C-L-X sheath provides the physical protection against mechanical damage as
required in NEC Section 727-3. It may be installed in both exposed and
concealed work, secured to supports not greater than 6 feet apart.
