Specifications
Conductors: Solid alloys per ANSI MC 96.1.
Insulation: Flame-retardant Okoseal®
(PVC) per UL Standard 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/synthetic polymer 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 Standard
13 and 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: Color-coded, flame-retardant Okoseal per UL Standard
13 and 2250.
Classification: UL Listed as Type ITC/PLTC - Instrumentation Tray
Cable/Power Limited Tray Cable for use in accordance with Articles 725 and
727 of the National Electrical Code.
The cables comply with UL 2250 and UL 13 for CL2 and CL3.
Applications
Okonite Loxarmor Type 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 hazardous locations. Also
for use as Power-Limited fire protective signaling cable (FPL) per NEC
Code 760. The Loxarmor (interlocked steel) sheath provides
the physical protection against mechanical damage as required in NEC
Section 727-4. It may be installed in both exposed and concealed work,
secured to supports not greater than 6 feet apart.
