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 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.
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 Standard 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 ands UL 13 for PLTC, CL2 and CL3.
Applications
Okonite Loxarmor Type SP-OS (Pair/triad - Individual and Overall Shield)
instrumentation cables are designed for use as instrumentation, process
control, and computer 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 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; 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 727-3. 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.
For dc service in wet locations X-Olene®
insulation is recommended.
