300V Elevator Traveling Cable (Communications Steel Center Core)
These cables are designed to complement existing or new communications cable installation and designed to track with other cables within the hoistway.
Center Steel Support Cable
Flexible, performance rated, galvanized steel wire rope support strand, manufactured to Military Specification MIL-W-83420.
The steel core has polyvinyl chloride insulation and a reinforcing tightly woven braid of cotton.
Insulated Conductors (optional)
Soft-annealed, bunched stranded, bare copper per ASTM Standards B3 and B174.
The conductors are insulated with flame retardant 60°C polyvinyl chloride and are rated at 300V in accordance with the requirements of UL 62, CSA C22 .2 No. 49 and the appropriate articles of the NEC and Canadian Electrical codes.
Each conductor is color- and number-coded for easy identification.
Two insulated No. 20 AWG soft-drawn bare copper conductors, PVC insulated, twisted with a bare drain wire.
The laminated polyester and aluminum foil tape creates 100% shield coverage.
The assembly has an overall colored PVC jacket and rated 300V.
RG-6, 75 ohm and 300V rated coaxial cable.
Fibrous-plied jute fillers to provide the cable a circular cross section, enhance torsion stability, and cushion the construction during flexing.
A tightly woven braid of cotton, rayon, or equivalent is applied over the core to help maintain core shape, torsion balance and add mechanical strength.
An overall jacket of polyvinyl chloride provides a smooth, flexible, abrasion-resistant covering complying with the flame test requirements UL 1581 and is CSA FT-1 flame rated.
