Specifications
Conductors: Bare soft annealed copper, Class B, 7-strand concentric
per ASTM B-8.
Insulation: Flame-retardant Okoseal®
(PVC) per UL Standard 13 and UL 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.
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 backed 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 UL 2250. A rip cord is laid longitudinally under the jacket to
facilitate removal.
Wire Armor: A serving of soft annealed galvanized steel wires
applied with a left-hand lay and a 90% minimum coverage.
Outer Jacket: Black, flame-retardant, low temperature Okoseal per
UL Subject 13 and UL 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.
The cable core complies with UL 2250 and UL 13 for PLTC, CL2 and CL3.
Applications
Okonite Single Wire Armored (SWA) Type P-OS (Pair/Triad - 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 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 for use in Class I,
Division 2, Class II, Division 2, or Class III, Division 2 hazardous
locations. Also for use as Power-Limited fire protective signaling cable
(FPL) per NEC Code 760.
The wire armor provides excellent longitudinal strength for use as a
messenger cable or for support in vertical drops (NEC Section 300-19) and
provides physical protection against mechanical damage.
For dc service in wet locations X-Olene insulation having an overall
aluminum C-L-X armor construction is recommended.
