Specifications
Conductors: Bare soft annealed copper, Class B, 7-strand concentric
per ASTM B-8.
Insulation: Flame-retardant, radiation-resistant Okozel, a modified
ETFE fluoropolymer. Cable meets or exceeds requirements for UL Standards
13 and 2250.
Conductor Identification: Pigmented black and white in pairs,
black, white and red in triads; white conductor numerically printed for
group identification.
Group Shield: Aluminum/Polyester tape overlapped to provide 100%
coverage, and a 7-strand coated 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, 7 mils
nominal Okozel insulation.
Assembly: Pairs or triads assembled with a 1 - 2 left-hand lay.
Flame-retardant, non-wicking fillers included where required to provide a
round cable, polyester tape overall.
Cable Shield: Aluminum-nylon-polyester tape overlapped to provide
100% coverage, and a 7-strand coated copper drain wire, same size as
conductor.
Jacket: Flame-retardant, radiation, oil, fuel, and
chemical-resistant Okozel. Cable meets or exceeds the requirements of UL
13 and UL 2250, NEMA HP-100 IEEE Std. 383, Type Test of Class IE Electric
Cables for Nuclear Power Generating Stations and is rated non-burning
under ASTM D635.
Classification: UL Listed as ITC/PLTC - Instrument Tray Cable/Power
Limited Tray Cable for use in accordance with Article 727 and 725 of the
National Electrical Code.
The cables comply with UL 2250 and UL 13 for PLTC, CL2 and CL3.
Applications
Okonite Okozel Type SP-OS (Pair/triad - Individual and Overall
Shield) instrumentation cables are recommended for use in either nuclear
powered or fossil fueled generating stations where continuity of critical
control circuits is of primary importance. 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 150°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. Listed for 1E Nuclear Station applications (meets
LOCA requirements). Also for use as Power-Limited fire protective
signaling cable (FPL) per NEC Code 760.
Okozel instrumentation cables are also recommended for high ambient
temperature areas up to 150°C (302°F)
in industrial applications or for cold weather installations in excess of
-65°C
(-85F).
Product Features
- Individual pairs or triads are numbered and color coded for
simplified hook-up.
- Individual pairs or triads are completely isolated.
- Maximum noise rejection.
- Communication wire included in each cable for voice communication
during installation or instrument calibration.
- 100% shield coverage for reduced electrostatic noise.
- Twisted to reduce electromagnetic pick-up.
- Outstanding nuclear radiation resistance even when exposed to LOCA
conditions.
- Low surface friction provides easier installation.
- Smaller and lighter diameter permits more cables per tray.
- 150°C continuous operating
temperature, 90°C in containment
area.
- Cold installation temperature in excess of -65°C.
- Exceptional abrasion resistance will not cut or tear.
- Flame-retardant and non-propagating. Passes IEEE 383 and UL Vertical
Tray Flame Tests.
- Low smoke emission.
- Chemically inert - unaffected by typical acids, bases, solvents and
cleaning agents, fuels and hydraulic fluids.
- High dielectric strength.
- Low dielectric constant.
- Qualified for nuclear generating stations, Class IE locations and
rated 90°C. See Okonite Sales for
heavier walls needed for Nuclear qualified cable.
