Double-Sheathed Double-Shielded Drag Chain Cable
Key Features
- Travel & speed: >100 m travel, acceleration up to 50 m/s², travel speed up to 8 m/s.
- Bending life: tested for >6 million bending cycles at 45 cycles per minute.
- Environmental resistance: cold resistant, hydrolysis and microbe resistant, resistant to oils and coolants.
- Chemical stability: radiation resistant, ozone and weather resistant, acid/alkali/solvent resistant.
- Mechanical durability: high abrasion resistance, notch resistant, withstands heavy mechanical loads, excellent flexing and torsion resistance.
- EMC performance: high electromagnetic immunity (double shield).
Applications
Designed for continuous reciprocating motion in both dry and damp industrial environments where frequent flexing is required. Typical installations include cable carriers (drag chains) in modern machinery standard components, logistics systems, control systems, and mechanical automation systems. Specific uses:
- CNC machine tools, electronic equipment, metal stamping presses
- Wood and stone processing machinery, glass and window/door machinery
- Injection molding machines, robotic arms, building machinery
- Heavy machinery plants, automotive manufacturing, lifting and transport equipment
- Automated warehouses, docks, fire trucks, indoor and outdoor environments
Especially suited to heavy mechanical loads and harsh environments such as coastal areas, ports, outdoor sites, high/low temperatures, and heavily contaminated locations.

FAQ
What makes this drag chain cable “double-sheathed and double-shielded”?
It features an inner TPE sheath and an outer PUR sheath for superior mechanical and environmental protection, plus two layers of tinned copper braid shielding (density ≥80%) that provide excellent protection against electromagnetic interference (EMI), making it suitable for sensitive signal transmission in moving applications.
What is the expected service life of this cable in a cable carrier?
Under proper installation, the cable exceeds 6 million bending cycles at 45 cycles per minute, with a travel distance of more than 100 meters and speeds up to 8 m/s. Actual service life depends on the minimum bending radius, acceleration, and environmental conditions. Our engineers can assist you in calculating the expected lifetime for your specific application.
Is this cable suitable for outdoor use and harsh environments?
Yes. The PUR outer jacket offers high resistance to UV radiation, ozone, hydrolysis, and microbial attack. It also resists oils, coolants, acids, alkalis, and many solvents. This makes the cable ideal for outdoor applications, coastal areas, ports, and heavy industry settings.
What are the available jacket colors, and can you customize the color code?
Standard jacket colors are black (RAL 9005), grey (RAL 7001), and orange (RAL 2003). The core color code follows the standard described above. Custom color codes and jacket colors are available upon request, subject to minimum order quantities.
Is the cable compliant with international safety and environmental regulations?
The conductors meet VDE 0295 Class 6 / IEC 60228 Class 6. The cable is manufactured under an ISO 9001-certified quality system, and insulation and jacket materials comply with RoHS and REACH requirements. Additional certifications such as UL, CSA, or EAC can be discussed based on your target market—please contact us with your requirements.
