Specifications
Conductors: Bare soft annealed copper, Class B, 7-strand
concentric per ASTM B-8.
Insulation: Flame-retardant Okoseal (PVC) per UL 13 and 2250, 15
mils nominal thickness, 105°C
temperature rating.
Conductor Identification: Pigmented black and white in pairs,
black, red and white in triads; white conductor numerically printed for
group identification.
Group Shield: Aluminum/Polyester tape overlapped to provide 100%
coverage, and a 7-strand tinned copper drain wire, two sizes smaller than
the conductor. All group shields are completely isolated from each other.
Communications Wire: 22 AWG, solid, bare copper conductor, 12 mils
nominal flame-retardant Okoseal insulation, 105°C
temperature rating.
Assembly: Pairs or triads 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 conductor.
Inner Jacket: Black, flame-retardant, low temperature Okoseal per
UL 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: Black, flame-retardant, low temperature Okoseal per
UL 13 and 2250.
Classifications: UL Listed as ITC/PLTC - Instrument Tray
Cable/Power Limited Tray Cable for use in accordance with Article 727 and
Article 725 of the National Electrical Code.
Cables comply with UL 2250 and UL 13 for PLTC, CL2 and CL3.
Applications
C-L-X Type SP-OS (Pair/triad - Individual and Overall Shield)
instrumentation cables are designed for use as instrumentation, process
control, 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 maximum
shielding against external interference is required, as well as shielding
among groups, particularly where the cable may be subject to abnormally
high current or voltage interference; 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 or direct burial. Suitable in Class I & 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. It may be installed in
both exposed and concealed work, secured to supports not greater than 6
feet apart.
The isolated individual shields over each pair, when properly grounded,
prevent crosstalk or capacitive coupling between adjacent pairs which
occurs with ac signals, particularly the pulse type.
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 physical protection against mechanical damage as
well as complete protection against moisture or gases entering the cable.
For dc service in wet locations X-Olene®
insulation is recommended.
