Q: Can I get pre-assembled cables with connectors?

Yes. With the igus® readycable® service , cables can be ordered pre-harnessed with connectors from brands like Siemens, Beckhoff, Allen Bradley, and SEW, ready for plug-and-play installation.

Engineered for maximum reliability in demanding environments

We offer over 260 motor cable variants engineered for continuous movement in energy chains. Designed for reliable motor power supply, the range includes spindle and single-core cables, as well as cables with three-phase conductors (L1, L2, L3) with or without a protective earth (PE). Optimised insulation and shielding ensure low capacitance and maximum EMC performance. Our portfolio also includes medium-voltage and highly torsion-resistant motor cables. With bending radii as low as 7.5 × d, these cables handle tight spaces and high mechanical stress.

Benefits:

Proven to last for millions of cycles within e-chain® cable carriers
Built to meet the engineering demands of industrial applications
CE, NFPA, and CEI-certified for diverse applications
Designed to withstand continuous, high-speed motion in harsh environments
Tested in the igus® laboratory for millions of e-chain® cycles, with a service life guarantee of up to 4 years.
Most of our motor cables use high-performance TPE as the outer sheath, ideal for extreme temperatures from -35 °C to +90 °C in energy chain applications. This makes them well suited for both deep-freeze and high-temperature environments. TPE offers outstanding abrasion resistance, outperforming PVC and PUR, making it the preferred choice for demanding applications requiring maximum service life.

Multi-core vs single core

Single-core cable designs are now an efficient alternative for large drives, offering key advantages over traditional four-core versions. A more cost-effective manufacturing process enables lower pricing, while the design itself is more robust and better suited to the limited installation space in energy chains, especially over long travels.

Smaller core diameters also simplify motor connections, although specialised mounting is required. With extensive experience in these applications, igus® provides the expertise and readily available products needed to deliver the right solution.

Applications with chainflex® cables

Cable in the forklift - a special challenge

An unusual application involves winding and unwinding cables on forklift masts via plastic rollers. The constant pulling and deflection place extreme strain on the cable stranding. After earlier issues, igus® collaborated with the customer to test a solution using specially bundle‑wound cores. This rope construction neutralises internal forces, eliminating corkscrew effects and core breakage. If you’re facing similar cable performance challenges, we can help find the right solution.

Frequently asked questions regarding motor cables

An SY cable is used for applications where mechanical protection is required.

igus® does not produce SY cables, why? SY stands for steel wire braided, and the galvanised steel wire braid are not designed to withstand repeated bending or flexing as the steel braid can fracture or unravel over time.

Alternatively, we offer our e-chains® as mechanical protection. igus® also provide CY and YY cables.
