Class I Flexible Strand With Braid
Low Smoke, Non-Halogenated Insulation With Cotton Braid, Lead-Free and Silicone-Free, UL Listed RHH/LS FT4 and VW-1, 90°C Dry, 60°C Wet, 600 Volts, UL Listed “For CT USE” (1/0 AWG and Larger), CSA AWM I B 105°C, 600 Volts, FT4
Scope
This specification covers the construction requirements for low smoke, non-halogenated, TelcoHyde™ 5221 insulated, cotton braided power wire and cable, type RHH/LS for use in accordance with the National Electrical Code.
The construction of the wire and cable is in accordance with Underwriters’ Laboratories requirements and the requirements of CSA for the FT4 flame tests. Sizes 1/0 AWG and larger are UL “CT USE” rated.
CONSTRUCTION
Size: 8 AWG through 750 KCMIL – Single conductor
Conductors: Class I (modified) bunched (8 and 6 AWG) and rope-bunched (4 AWG and larger) stranded tinned copper conforming to ASTM B-33 and Underwriters’ Laboratories requirements. An opaque mylar tape shall be applied over the conductor to facilitate stripping.
Insulation: 90°C rated limited smoke, non-halogen, TelcoHyde™ 5221 conforming to Underwriters’
Laboratories Standard 44 and Telcordia Specification GR-347-CORE, also CSA 105°C AWM rated. The insulation has a limiting oxygen index of 35%.
Separator: On sizes 6 AWG and larger, a 1 mil clear mylar tape shall be applied over the insulation.
Covering: On all sizes, a natural cotton braid conforming to UL requirements is applied overall. A section of completed cable has a limiting oxygen index of 35%.
Finish: A moisture resistant, fire retardant saturant and a colored finisher is applied to the braid.
Surface Marking: Two sides of the cable shall be printed using an ink of contrasting color and with the following information: “TelcoFlex™ IV/KS24194™ L4 NON-HAL (SIZE) AWG (OR KCMIL) 600V. RHH/LS FT4 (UL) OR AWM 3578 VW-1 E18321—A.I.W. CORP.—LL8825 CSA AWM I B 105°C 600V. FT4 (YEAR) (SEQ. FTG. ON 1 SIDE)”.
For sizes 1/0 AWG and larger add “FOR CT USE” before “(UL)”
Testing: Physical and electrical tests in accordance with UL Standard 44 requirements.
Labels: UL tags and labels shall be applied to each reel.
