Price (Per FT.)
Okonite Single Wire Armored (SWA) Type P-OS (Pair/Triad - Overall Shield) instrumentation cables are designed for use as instrumentation, process control in ITnon-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.
Conductors: Bare soft annealed copper, Class B, 7-strand concentric per ASTM B-8.
Insulation: Flame-retardant Okoseal® (PVC) per UL Standard 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. Pair or triad assembled with left-hand lay.
Communication Wire: 22 AWG, solid, bare copper conductor, 12 mils nominal flame-retardant Okoseal insulation, 105°C rating.
Assembly: Pairs or triads assembled with left hand lay. Fillers included where required to provide a round cable.
Cable Shield: Aluminum/Polyester tape over-lapped to provide 100% coverage, and a 7-strand tinned copper drain wire, same size as the conductor.
Inner Jacket: Black, flame-retardant, low temperature Okoseal®(PVC) per UL 13 and UL Standard 2250. A rip cord is laid longitudinally under the jacket to facilitate removal.
