Bare, Stranded Copper Conductor B Okozel Insulation
Insulation
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 and has low permeability. Okozel is flame retardant
and non-propagating, passes the IEEE 383 and UL 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 and retains all useful physical properties at
temperatures down to -100°C (-148°F). Okozel is a radiation resistant dielectric and
meets or exceeds all requirements of IEEE Standards 383 and 323.
Specifications
Conductor: Bare copper per ASTM B-3, stranded per ASTM B-8, Class B in sizes 14 to
2/0 AWG, Class C in 4/0 AWG.
Insulation: Flame-retardant, radiation-resistant Okozel, a modified ETFE
Fluoro-polymer per NEMA Std. HP-100.2.
Insulated conductor meets or exceeds the requirements of IEEE Std. 383, Type Test of
Class IE Electric Cables for Nuclear Power Generating Stations and is rated
"non-burning" under ASTM D635.
Listed by Underwriters Laboratories, Inc. as Type Z or ZW.
Applications
Okozel insulated conductors are recommended for use in either nuclear powered or fossil
fueled generating stations where continuity of service in critical circuits is of primary
importance. These conductors, which are rated 150°C in dry and 75°C in wet locations
(90°C as Class 1E), permit smaller conduit use through higher ampacities and thinner
insulation walls than comparable XLP or rubber constructions.
Okozel conductors are also recommended for high ambient temperature areas up to 150°C
(302°F) in industrial applications or for cold weather installations to -65°C (-85°F). |
