300V Elevator Traveling Cable (Steel Center Core)

Product Overview

The 300V Elevator Traveling Cable with Steel Center Core is a rugged, flexible cable specifically engineered for vertical movement applications in elevators, dumbwaiters, personnel hoists, and material hoists. Featuring a galvanized steel wire rope support core, flame-retardant PVC insulation, and a robust overall jacket, this cable meets stringent UL, CSA, and NEC requirements. Optional shielded pairs and coaxial cables are available for communication and signal transmission.

Key Characteristics

Cable Construction

Center Steel Support Cable

• Flexible, performance-rated galvanized steel wire rope support strand manufactured to Military Specification MIL-W-83420.

• Coated with 60°C flame-retardant polyvinyl chloride (PVC) insulation.

• Reinforced with a tightly woven braid of cotton or rayon.

Insulated Conductors

• Soft-annealed, bunched stranded bare copper per ASTM B3 and B174.

• Insulated with flame-retardant 60°C PVC, rated 300V (UL 62, CSA C22.2 No. 49).

• Each conductor is color and number-coded for easy identification.

Shielded Pairs (Optional)

• Two insulated 20 AWG soft-drawn bare copper conductors, PVC insulated, twisted with a bare drain wire.

• Laminated polyester/aluminum foil tape provides 100% shield coverage.

• Overall colored PVC jacket, rated 300V.

Coaxial Cable (Optional)

• RG‑6, 75 ohm, 300V rated coaxial cable.

Fillers

• Fibrous-plied jute fillers create a circular cross-section, enhance torsion stability, and cushion the construction during flexing.

Braid

• A tightly woven braid of cotton, rayon, or equivalent applied over the core to maintain core shape, torsion balance, and add mechanical strength.

Outer Jacket

• Overall PVC jacket – smooth, flexible, abrasion-resistant.

• Complies with flame test requirements of UL 1581 and CSA FT-1.
