Cables in drag chain systems crack, stiffen, and fail — costing unplanned downtime and replacement labor. Oil mist, constant flexing, and EMI noise degrade standard cables within months. This 4 core PUR shielded cable is engineered to outlast them in high-cycle cable carrier applications.Product OverviewImported PUR (polyurethane) jacketed cable, 4 cores, 2.5mm² (SK14AWG) tinned copper conductors, overall shield with tinned copper braid. Designed for continuous flexing in cable carriers, drag chains, and reciprocating motion systems. Resists oil, cutting fluids, and abrasion while maintaining signal integrity in electrically noisy environments.Core Specifications

Why This Cable Performs Where Others Fail
- PUR jacket stays supple at low temperature. Unlike PVC cables that harden below -10°C, this PUR formulation remains flexible down to -40°C. No cracking in cold storage lines or outdoor CNC enclosures during winter shifts.
- Oil and fluid resistance built into the material. PUR resists mineral oil, hydraulic fluid, cutting emulsions, and grease. Tested per ISO 1817 — no swelling or softening after 720h oil immersion. Ideal for machining centers and press lines where oil mist is constant.
- Millions of flex cycles without conductor breakage. Tinned copper strands with optimized lay length absorb repeated bending stress. Rated for 10+ million cycles in drag chain at rated bend radius — verified in cable carrier test rigs, not just datasheet claims.
- Braided shield blocks EMI in servo-dense setups. 85%+ braid coverage suppresses electromagnetic interference from VFDs and servo drives running alongside. Signal cores stay clean in multi-axis robot cells and packaging machines.
Applicable Industries & Scenarios
- Automation production lines — drag chain routing between moving gantries
- CNC machining centers — oil-rich environments, reciprocating tool axes
- Robotic cells — multi-axis arm cable carriers, EMI-heavy servo zones
- Material handling — conveyor systems, stacker cranes, AGV power feeds
- Packaging machinery — high-speed pick-and-place, frequent flex points
