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 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 Subject 13 and UL 2250. A rip cord is laid longitudinally under the
jacket to facilitate removal.
Loxarmor Sheath: An interlocking, galvanized steel armor provides
mechanical protection against cut-through and crushing. All four sides of
the steel tape are galvanized to prevent corrosion.
Outer Jacket: Black, flame-retardant, low temperature Okoseal per
UL 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 Cables comply with UL 2250 and UL 13 for PLTC, CL2 and CL3..
Applications
Okonite Loxarmor Type P-OS (Pairs/triads - Overall Shield) instrumentation
cables are designed for use as instrumentation, process control in ITC
non-classified or labeled 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; or direct burial. Suitable 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
Loxarmor (interlocked steel) sheath provides physical protection against
mechanical damage. It may be installed in both exposed and concealed work,
secured to supports not greater than 6 feet apart.
The overall shield eliminates most of the static interference from the
electric field radiated by power cables and other electrical equipment.
For dc service in wet locations X-Olene®
insulation is recommended.
