INTRODUCTION

Our PUR polyurethane drag chain cable is premium high-flex cable built for long-term reciprocating movement inside energy chain carriers. Compared to standard PVC jacket drag cables, the polyurethane outer sheath delivers outstanding resistance to machine oil, cutting coolant, abrasion, tearing and hydrolysis, making it the top choice for harsh industrial workshops. Manufactured directly at our Shanghai factory, this flex cable supports over 10 million continuous bending cycles, stable power & signal transmission for CNC, robotic arms and automated assembly lines. We wholesale and custom tailor PUR drag chain cables for clients across Europe, North America and Southeast Asia with reliable shipping schedules.

Cable Internal Construction

Conductor

IEC Class 6 extra-fine bare/tinned stranded copper conductors eliminate metal fatigue breakage under high-speed repeated flexing, the core foundation of durable drag chain operation。

Core Insulation

High elastic flexible insulation material maintains stable dielectric performance during constant bending, prevents inner core short circuit.

Shield Layer (Optional)

High coverage tinned copper braid shielding for shielded models, excellent anti-crosstalk and EMC performance for precision signal transmission.

PUR Polyurethane Outer Sheath

Premium industrial-grade PUR compound, the signature layer of this cable; delivers wear-proof, oil-proof, tear-proof and hydrolysis-proof performance for dynamic motion environments。

Main Application Fields

CNC lathes, laser cutters, machining centers (widely adopted by German, Polish machine tool manufacturers)

6-axis industrial robots, automated handling & welding robotic systems

High-speed packaging, printing, textile and injection molding machinery

Automated warehouse conveyor lines, logistics sorting equipment

Medical automation testing devices, food processing production lines

Outdoor movable port equipment, low-temperature workshop energy chain systems

About Us

ADVANTAGES

Unmatched oil & coolant resistance: PUR repels mineral oils, water-based coolants and industrial chemical splashes, far better than ordinary PVC sheath
Extreme abrasion & notch resistance: Thick polyurethane jacket resists scraping inside drag chains, small scratches will not expand into cable rupture
Wide temperature adaptability: Flexible from -40°C up to +80°C, works well in cold warehouses and hot machining workshops
Long flex lifespan: Matched with Class 6 ultra-fine stranded copper conductors to achieve 10,000,000+ reciprocating bend cycles
Optional EMC shielding: Tinned copper braid shield blocks motor electromagnetic interference for precise sensor & bus signal
Full export certifications: CE, RoHS, REACH compliant, halogen-free grade available for food & medical automation
Customizable specs: Adjust core count, AWG, cable length, shield structure and printing per project requirements
