Is your production line stopping because of broken cables?
You know the feeling. Everything is running smooth. The conveyors are moving. The robotic arm is welding. Then suddenly—stop. The control cable inside the drag chain snapped again. You lose hours of production time. You pay high repair costs. And you worry it will happen again next week.Cheap cables look good on paper. But in the real world, they crack. They stiffen up in the cold. They get crushed by moving parts. This is not just an annoyance. It is a money pit.You need a cable that moves like a snake but is tough like a tank. You need the reliability of a German engineering standard. You need a cable built for millions of movements, not just a few thousand. This is where our 25-core 0.75mm² flexible drag chain control cable comes in. It is designed to end the headache of constant cable failure.
What makes this 25×0.75mm² cable special?
This is not a standard wire. It is a high-flex control cable designed for dynamic applications. The “25×0.75mm²” tells you exactly what you get. You have 25 separate cores inside one outer jacket. Each core has a cross-section of 0.75 square millimeters. This size is the “Goldilocks” of control cables. It is thick enough to carry power and signals reliably, but thin enough to stay flexible and fit inside tight drag chains.The conductor is made of bare copper. But it is not a solid, stiff rod. We use Class 5 fine-wire stranding. This means each wire is made of many tiny copper threads twisted together. This construction allows the cable to bend and twist repeatedly without breaking the metal inside. It handles mechanical stress better than solid core cables.The insulation and outer sheath use high-quality PVC (Polyvinyl Chloride). This material resists oil, grease, and coolants. It also has good flame-retardant properties. If your factory floor gets hot, this cable stays safe. It meets the IEC 60332-1-2 standard for flame resistance.

Where should you use this cable?
You will find this cable working hard in tough environments. It is the muscle behind the machines.
Low-speed drag chains and conveyors
This is the bread and butter for this cable. It connects motors, sensors, and control boxes on assembly lines. The PVC sheath resists abrasion from the chain links. It does not snag or tear.
CNC Machines and Robotics
In a CNC machine, the control head moves constantly. The cable needs to flex millions of times. The fine-stranded copper core handles this constant flexing. It prevents “work hardening” where the metal becomes brittle and snaps.
Production and Packaging Lines
Factories are dirty places. Oil, water, and dust are everywhere. This cable’s tight PVC jacket keeps moisture out. It protects the copper signals inside. This ensures your sensors read correctly every time.
Building Installations
You can also use it for fixed wiring in walls or conduits. It is robust enough to handle rough handling during installation. The flame-retardant PVC adds a layer of safety to your building infrastructure.
Why choose the “German Brand” quality philosophy?
You asked for a German brand like LAPP. Why? Because in the cable world, “German Engineering” means consistency.When you buy a cheap generic cable, one batch might be great. The next batch might have a thin spot in the insulation. Or the copper might be impure. This inconsistency causes random failures.High-quality standards like VDE 0250 or IEC 60227 ensure every meter of cable is tested.
- Consistency: Every core has the exact same resistance.
- Purity: The copper is 99.9% pure for maximum conductivity.
- Durability: The PVC mix is optimized for flexibility, not just stiffness.
- Testing: Every batch undergoes high-voltage spark tests.
We apply this same strict quality control. We use machines from Europe to twist the copper strands. We use laser measuring to check the diameter. We do not ship cable that we would not use in our own factory.
How to handle installation and safety
Even the best cable fails if installed wrong. Here are simple tips to make it last 10 years.
- Respect the Bending Radius: Do not bend the cable sharply. Keep the curve smooth. If you kink it, you damage the copper strands inside. The minimum radius for moving is usually 15 times the cable diameter (about 20 cm for this cable).
- Temperature Matters: Do not install this cable below -5°C. The PVC gets brittle in extreme cold and can crack if you bend it. If you must work in the cold, warm the cable up first.
- Don’t Overstuff the Tray: If you put too many cables in one duct, they generate heat. This cable works best when it can breathe a little.
- Use Proper Glands: When the cable enters a box, use a strain relief gland. This stops someone from pulling on the wires directly. It protects the connection points.
Frequently Asked Questions about this Cable
Can I use this for power and data in the same cable?Yes. With 25 cores, you have plenty of space. You can use 2 cores for 24V power and the other 23 cores for control signals or data. Just make sure you separate high-power lines from sensitive signal lines if possible, or use shielded pairs for data.Is this cable oil-proof?The standard PVC version has “oil-resistant” properties. It can handle incidental contact with machine oils and grease. However, if your cable will be submerged in oil 24/7, you should look for a PUR (Polyurethane) sheathed version. PUR handles heavy oil exposure much better than PVC.What is the difference between YY and ÖLFLEX®?YY is a common European standard code for flexible control cable. ÖLFLEX® is LAPP’s specific brand name for their cables. They often meet the same technical standards (like VDE), but LAPP usually has tighter quality control and better consistency in the jacket material. Our cable meets the YY standard but is manufactured to LAPP-level quality.How heavy is it?It weighs about 305 kilograms per kilometer. For a 100-meter roll, that is roughly 30.5 kg. It is heavy enough to be durable but light enough for one person to handle during installation.
