Cables in drag chains crack within months. Robotic arm wiring fails under repeated flex cycles. Downtime from cable replacement eats into production hours — and standard PVC jackets simply don’t hold up in high-motion automation environments.This imported 4-core 1.5mm² cable is built for exactly those conditions. PUR (polyurethane) jacket with fine-stranded conductors delivers consistent flex life in tight-radius cable carriers and articulated robotic arms. Soft orange color for easy identification in complex cable runs. No shielding — designed for power and signal in controlled automation setups where EMI is not the primary concern.Core Parameters

Why This Cable Lasts Longer in Motion
- PUR jacket resists abrasion and cutting. In drag chain applications with chain speeds above 1.5 m/s, PUR outperforms PVC by 3–5× in abrasion cycles. The soft orange compound stays flexible even after millions of flex strokes — no hardening, no flaking.
- Fine-stranded conductors handle tight bends. Each conductor uses 30+ strands of 0.22mm wire. This distributes mechanical stress across the strand bundle, preventing conductor breakage when routed through small-radius cable carriers or robotic wrist joints.
- Low torsion and lightweight. PUR density (~1.1 g/cm³) keeps cable weight down — critical for robotic arm payloads. Reduced torque on drag chain links means less wear on the carrier itself, not just the cable.
- Oil and coolant resistant. PUR handles hydraulic oil, cutting fluids, and light lubricants common in CNC machines and welding robots. No swelling, no jacket degradation in typical shop-floor environments.
