and Jacket
Okozel is Okonite's trade name for ETFE Fluoropolymer, a modified Ethylene
Tetrafluoroethylene. Okozel is extremely rugged with excellent resistance
to cut-through and abrasion. It is chemically inert. Okozel is
flame-retardant and non-propagating, passes the IEEE 383 vertical tray
flame test, and is rated non-burning under ASTM D635. It is rated for 150°C
(302°F) conductor operating
temperature for continuous use (90°C)
within the containment area) and retains all useful physical properties at
temperatures down to -100°C (0148°F).
Okozel is a radiation resistant dielectric and meets or exceeds all
requirements of IEEE Standards 383 and 323.
Specifications
Conductors: Solid alloys per ANSI MC 96.1
Insulation: Flame-retardant, radiation-resistant Okozel, a modified
ETFE fluoropolymer.
Conductor Identification: Pigmented insulation on individual
conductors.
Assembly: Conductors assembled with left-hand lay.
Cable Shield: Aluminum-nylon-polyester tape overlapped to provide
100% coverage, and a 7-strand coated copper drain wire, same size as
conductor.
Jacket: Heavy duty, flame-retardant, radiation, oil, fuel and
chemical resistant Okozel.Cable meets or exceeds the requirements of UL
Standards 13 and 2250, NEMA HP-100, IEEE Std. 383, Type Test of Class IE
Electric Cables for Nuclear Power Generating Stations.
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 CL2 and CL3.
Applications
Okonite Okozel Type P-OS (Pair/triad - Overall Shield)
Thermocouple Extension 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 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 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 thermocouple extension 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 (-85°F).
Product Features
- Good noise rejection.
- 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 acids, bases, solvents and cleaning
agents, fuels and hydraulic fluids.
- High dielectric strength.
- Low dielectric constant.
- Qualified for nuclear generating stations in Class IE locations and
rated 90°C. See Okonite Sales for
heavier walls needed for Nuclear qualified cable.
