Cables in drag chains crack after a few months. Insulation peels under repeated bending. Brake signals fail mid-cycle — and the whole production line stops. If you are sourcing motor power and brake cables for moving machinery, you know the pain: cheap cables survive lab tests but die on the floor.This imported 6-core cable is built for exactly that. It combines 4 power cores (1.5 mm²) with 2 signal cores (0.5 mm²) in a single jacket — one cable handles motor drive and brake control. Designed for continuous flexing in drag chains, cable carriers, and robot arms. No separate power and control cables to route. Cleaner build. Fewer failure points.Core Specifications

Why This Cable Holds Up Where Others Don’t1. Engineered for drag chain motion — not just “flexible”The conductor stranding and jacket formulation are matched for drag chain travel speeds up to 5 m/s. Most “flexible” cables are only rated for occasional movement. This one is rated for continuous reciprocating motion — the difference shows in service life.2. Combined power + brake signal in one jacketThe 4×1.5 mm² cores carry motor power. The 2×0.5 mm² cores handle brake release and status signals. One cable pull, one gland entry, one strain relief. Saves routing time and reduces snag points inside the energy chain.3. PUR jacket resists the three killers in machine shopsCutting coolant, hydraulic oil splashes, and abrasion from chain links — PUR handles all three. PVC jackets swell and crack in oil. This cable stays intact where PVC fails within weeks.4. Tinned copper conductors prevent oxidation in humid or oily environmentsStandard copper oxidizes at the strand level under heat and moisture. Tin plating keeps contact resistance stable over years — critical for brake signals where a voltage drop means the brake does not release.Applicable Industries & ScenariosCNC machining centers, robotic welding cells, pick-and-place systems, servo-driven press lines, automated packaging equipment, gantry cranes, AGV power feeds, and any application where motor power and brake control share a moving cable path.Sourcing, Customization & SupportWe supply from stock in standard lengths and spool sizes. Non-standard core combinations, jacket colors, shielding options, and custom lengths are available — lead time typically 2–3 weeks for engineered orders. Every batch ships with a flex-cycle test report.
