Shielded Servo Cable for Drag Chain Applications

Engineered for dynamic power chain and cable carrier systems, our shielded servo cable connects variable frequency drives (VFDs) and servomotors with reliable power and signal integrity. It is suitable for power circuits in automated equipment, operating in dry or damp indoor environments, and offers UV resistance for outdoor exposure under normal mechanical loads. The combination of high-flex copper conductors, pair-twisted cores, a dense tinned-copper braid shield, and an imported PUR jacket makes this cable an excellent choice for robotics, machine tools, and material handling systems where continuous flexing and EMI protection are critical.

Key Features & Construction

Insulation: Highly flexible insulation
Core configuration: Cores twisted in pairs for enhanced noise immunity
Inner sheath: Imported high-grade PUR (polyurethane)
Shielding: 85% coverage tinned copper braid, effective against electromagnetic interference (EMI)
Outer sheath: Imported high-grade PUR, black (RAL 9005) or grey (RAL 7001)
Rated voltage: 300/300 V
Test voltage: 2000 V
Temperature range:
– Fixed installation: -50 °C to +90 °C

Minimum bending radius:
– Fixed: 5 × outer diameter
– Flexing: 8 × outer diameter

Why PUR Jacket?

The imported polyurethane outer sheath delivers outstanding mechanical toughness and chemical resistance. It resists mineral oils, cutting fluids, abrasion, and UV radiation, significantly prolonging cable life in harsh industrial settings. Combined with the highly flexible insulation and tight shielding, this design ensures stable data and power transmission even under millions of flex cycles in energy chains.

Typical Applications

VFD / servo motor power and feedback cabling in drag chains
Automated assembly lines, pick-and-place machines, and robotics
Machine tools, injection moulding machines, and packaging equipment
Any moving cable system requiring superior EMI shielding and flex durability

We can manufacture the cable to meet CE directives and customise upon request for UL/CSA, or other regional approvals. Contact us for a tailored solution.

FAQ

What type of cable is best for connecting a VFD to a motor in a moving cable chain?
You need a shielded, high-flex cable that can withstand continuous bending and reject electrical noise. Our servo shielded cable features a tinned copper braid with 85% coverage and a PUR jacket, specifically designed for such VFD/motor drag chain applications.

Does this cable comply with VDE or UL standards?
The conductor is manufactured according to VDE 0295 Class 6 and IEC 60228 Class 6. The complete cable can be built to CE, UL, or CSA standards based on your project requirements. Please share your certification needs when you request a quotation.

Can I order custom jacket colours or alternative materials?
Yes. While standard stock colours are black (RAL 9005) and grey (RAL 7001), we provide OEM options for jacket colour and material (TPE, PVC, etc.). Minimum order quantities apply for custom production.

What is the minimum order quantity (MOQ) and can I get a sample first?
We support both sample evaluation and volume orders. Our standard MOQ is 500 metres per size, but this is negotiable for first-time projects and prototypes. Just tell us the required length and specifications.

Is this cable suitable for outdoor or wet environments?
The PUR jacket is UV-resistant and suitable for outdoor use under mechanical loads. It also withstands damp indoor conditions. However, for continuous immersion or extreme outdoor exposure, we recommend discussing your specific environment with our engineers to confirm suitability.
