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 alluseful physical properties at temperatures down to -100°C (-148°F).
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, 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).
Specifications Conductor:Uncoated soft copper per ASTM B-3. Sizes smaller than #8 are compress stranded per ASTM B-8. Sizes #8 and larger are compact stranded per ASTM B-496. Insulation:Flame-retardant, radiation resistant Okozel, a modified ETFE Fluoropolymer per NEMA Std. HP-100.2. Insulated conductor is rated “non-burning” under ASTM D635. Listed by Underwriters Laboratories, Inc. as Type Z or ZW.
