3X1.5+1X1.0mm² PUR Cable

When cable failure is not an option in high-motion zones

A single broken conductor inside a cable drag chain can stop an entire packaging line. The cost of that downtime outstrips the price of the cable 20 times over — often before the maintenance team even traces the fault. You need a power and control cable that bends continuously, resists cutting oils, and refuses to degrade inside abrasive cable carriers. The 3X1.5+1X1.0mm² PUR cable is built for exactly this. Its polyurethane jacket withstands the physical abuse that kills PVC cables early. As a result, you replace cable less often and keep production on schedule.

Why polyurethane changes the math on total cost

PUR jacket: a shield against oil, wear, and weld spatter

Feature: Tough polyurethane outer sheath, resistant to mineral oils, hydrolytic degradation, and notch propagation.
Advantage: PUR’s tear strength sits well above standard PVC or rubber compounds. It does not swell or crack after continuous contact with cutting fluids or grease.
Benefit to your facility: Fewer unplanned cable swaps on CNC machines, presses, or lubrication-heavy lines. Maintenance teams shift from reactive repair to planned PMs.

Fine-stranded bare copper and the 3+1 core layout

Feature: 3 power conductors (1.5 mm²) plus a dedicated 1.0 mm² ground/control conductor, made from bare copper fine wire strands.
Advantage: High bending compliance and excellent conductivity. The symmetrical 3+1 design simplifies wiring of variable frequency drives, servo motors, and sensors that need a clean earth reference.
Benefit to your project: One cable handles both power delivery and signal grounding. Panel layout becomes cleaner, termination errors drop, and electromagnetic noise at the motor frame stays low.

Tight bend radius in continuous flex applications

Feature: Engineered conductor lay length and low-friction PUR surface allow operation inside drag chains and robotic arms.
Advantage: The cable survives millions of flex cycles at acceleration rates that would tear a stiff cable apart.
Benefit to your automation cell: Cable-related downtime falls sharply. Production OEE climbs because the weakest link in the power chain — the cable itself — is no longer the failure point.

Flame retardance and workshop safety

Feature: Flame-retardant behaviour according to horizontal flame spread standards.
Advantage: If the cable ignites under a fault condition, the flame does not propagate along the cable route.
Benefit to your plant: You reduce fire load inside cable trays and trunking. This supports compliance with site safety protocols and insurer requirements without adding oversize conduit.

Technical specifications

Full dimensional drawings and S-parameter data are issued with every quotation. No generic ballpark numbers — you get the data tied to your exact build.

Where this cable does its best work

• Machine tool and CNC drag chains — resists cutting oils and coolants that degrade PVC jackets in 6 months.
• Industrial robots and linear actuators — maintains continuity through twisting and high-bending cycles on wrist axes or cable carriers.
• Material handling and packaging lines — reduces spark-outs and earth faults inside densely packed cable tracks where abrasion is constant.
• Food and beverage processing — withstands washdown splashes and mild chemical exposure when proper glands are specified.
• Test and measurement carts — provides a clean earth reference for sensitive data acquisition while powering assemblies on moving rigs.

Compliance and testing background

We do not ship and hope. Every production batch is tied to a test regime agreed upon during order engineering. Depending on your project, the cable can be supplied to satisfy:

• ✅ IEC 60228 conductor class requirements
• ✅ EN 50363 / VDE 0207 insulation and sheath testing
• ✅ IEC 60332-1 flame propagation test (single cable)
• ✅ CE marking and EU RoHS 2011/65/EU
• ✅ ISO 9001:2015 manufacturing traceability
• ✅ Oil resistance testing per EN 50363-10-2 or similar — scope defined with your quality team

Third-party witness testing for OEM procurement contracts is standard procedure. Mill certificates, elongation reports, and spark test logs are delivered with the shipment.

FAQ

Can I order a shielded variant for longer VFD runs?
Yes. A tinned copper braid shield with coverage up to 85 % is available. Shielding not only reduces radiated EMI but also gives the cable additional mechanical armour in raceways. You must specify the desired coverage rate and operating frequency. We will then check bend radius and attenuation against your application data before confirming the build.

What jacket colour is best for a dark oil environment?
Grey confirms to RAL 7001 and hides oil stains, which keeps walkaround inspections efficient. Black jackets provide better UV resistance if the cable route moves between indoor and outdoor sections. White or orange jackets are often selected for food production areas for foreign object detection. We hold compound stocks for all four options. The functional difference is minimal — the choice is driven by your site’s visual management or hygiene SOPs.

What if my required continuous flex cycle count exceeds the catalogue value?
Catalogue life ratings assume a standardized bend radius and acceleration profile. If your actual installation places a tighter bend or higher acceleration, we run an application-specific flex test using your exact routing parameters. This verification ups the confidence level for warranty replacements and lets your automation team plan cable replacement intervals on a data-backed calendar instead of guesswork.

No two cable carrier installations are identical. Carrier radius, travel length, ambient temperature, and chemical exposure stack up into a combination that generic stock rarely fits perfectly. Send your technical requirements — even a sketch of the energy chain layout will do. Our engineering team cross-checks jacket material, bend radius, shield coverage, and colour code before issuing your quotation. You will receive a full dimensioned data sheet, not just a price.
