CONSTRUCTION
Size: 14 AWG through 750KCMIL Single Conductor
Conductors: Class B stranded, tin-coated copper conforming to ASTM B-33 and Underwriters Laboratories requirements. An opaque Mylar tape shall be applied over the conductor to facilitate stripping.
Insulation: 105°C rated low smoke, non-halogen TelcoHyde® conforming to Underwriters Laboratories Standard 44, Subjects 509 and 758, and CSA C22.2 No. 210-11. In addition, TelcoHyde® complies with the requirements of Telcordia Specification GR-347-CORE. 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 and Finisher On all sizes, a natural cotton braid conforming to UL Standard 44 requirements is applied overall. A section of completed cable has a Limiting Oxygen Index of 35%. A moisture resistant, fire retardant saturant and a colored finisher are applied to the braid.
