Stop Wasting Money on Cables That Snap in Your Cable Chains
You know the feeling. You just fixed the production line. The machine is running smooth. Then, suddenly, the system stops. You check the control cabinet, and there it is—the cable inside the cable chain is broken. The copper wires are fatigued. The sheath is cracked. Now you face hours of downtime. You lose money every minute the line is down.This happens because you are using standard cables. They are too stiff. They cannot handle the constant movement. They get hot. They absorb oil and fall apart. In machine tools and assembly lines, flexibility is not a luxury. It is a necessity. You need a cable that moves like a snake but protects the signal like a tank. You need a cable designed for 5 million bending cycles. You need the ÖLFLEX® CLASSIC FD 810 P 18G1.5 mm². This is not just a wire. It is the lifeline of your machine.
Why This 18-Core Cable is Different
Most cables fight against the movement. This cable moves with the machine. It is built for power chains. It is built for robotics. It is built for the hardest industrial environments.The “FD” in the name stands for “Flexible Drive.” The “810” is the series number for high-performance chain cables. The “P” tells you it has a special Polyurethane (PUR) outer sheath. Why does this matter? Because standard PVC gets sticky and cracks. PUR is tough. It resists oil. It resists abrasion. It lasts longer.This specific version has 18 cores. Each core is 1.5 mm². This gives you plenty of power for motors and plenty of paths for control signals. It is a heavy-duty workhorse.
Technical Specifications You Can Trust
We do not hide behind fancy words. Here are the real numbers. These numbers tell you if the cable fits your machine.
- Conductor Material: Bare copper. We use Class 6 extra-fine stranding. This means the wire is made of many tiny copper threads. It bends easily without breaking.
- Number of Cores: 18. This includes a protective earth conductor (Green/Yellow).
- Conductor Cross-Section: 1.5 mm².
- Nominal Voltage: 300/500 V AC. This is standard for industrial control circuits.
- Test Voltage: 4 kV. It can handle power surges.
- Current Rating: Up to 18 Amps (depending on installation).
- Outer Diameter: Approximately 15.6 mm. Check your cable chain size!
- Weight: Around 201 kg/km. It is heavy because it has real copper and good shielding.
- Outer Sheath Material: Polyurethane (PUR).
- Core Insulation: PVC.
- Color: Grey (RAL 7001).
- Bending Radius:
- Fixed installation: 6 times the diameter (about 93 mm).
- Flexing in chains: 7.5 times the diameter (about 117 mm).
- Note: Do not bend it sharper than this, or you will damage it.
Built for the Worst Conditions
Your factory is not a clean room. It is dirty. It is oily. It is hot. This cable is ready for it.Oil and Chemical ResistanceMachine tools leak oil. Coolants splash around. Standard cables swell up when they touch oil. The insulation fails. The signal gets lost. The ÖLFLEX® FD 810 P has a PUR sheath that laughs at oil. It resists mineral oils, grease, and many chemicals. It keeps the copper safe inside.Abrasion ResistanceIn a cable chain, cables rub against each other. They rub against the plastic guide rails. This causes wear. The “Low-adhesive surface” of this cable reduces friction. It slides smoothly. It does not get stuck. This means less heat build-up and less wear on the outer skin.Temperature RangeMachines get hot. Cold stores are freezing. This cable handles it.
- Fixed use: -40°C to +80°C.
- Flexing use: 0°C to +70°C.
- Tip: Do not flex it when it is frozen. It will crack.
Flame RetardantSafety comes first. If a fire starts, you do not want the cable to spread it. This cable is flame-retardant according to IEC 60332-1-2. It is hard to ignite.
Perfect for These Applications
Where should you use this 18G1.5 cable? Use it where movement happens. Use it where data and power need to travel together.Cable Chains and Drag ChainsThis is the main job. It supplies power to moving parts. It sends signals back to the PLC. It is rated for 5 million alternating bending cycles. That is years of service without replacement.Machine Tools and CNCCNC machines vibrate. They move fast. The control cables need to be flexible. This cable is perfect for connecting the control panel to the spindle or the servo motor.Robotics and Assembly LinesRobots move their arms. The cables in the arm need to be light but strong. The 18 cores allow you to run sensors, encoders, and power all in one cable. This saves space and weight.Outdoor Use (With Care)You can use it outside. But remember, the standard version is not UV-protected. If the sun hits it directly for months, the sheath will fade. If you need it in the sun, put it in a conduit or ask us about the UV-resistant version.Food and PackagingIs it food safe? The material is resistant to hydrolysis and microbes. It is often used in food packaging machinery. But it is not a “food grade” certificate by default. Check with your safety officer.
Installation and Handling Tips
You bought a great cable. Now do not mess up the installation.1. Measure the Bending RadiusThis is the most important rule. The cable needs a curve. It cannot bend at a sharp 90-degree angle right at the connector. Give it a loop. The minimum radius is 7.5 times the cable diameter. If you bend it too tight, the impedance changes. The signal gets noise. The wire breaks.2. TwistingWhen you pull the cable into the chain, do not let it spin. If the cable twists 360 degrees over a length of 1 meter, you have a problem. It creates loops that catch on the chain dividers.3. ClampingUse the right cable glands. Since the outer diameter is 15.6 mm, you need a gland that fits 14-16 mm. Do not squash the cable with the gland. It will damage the round shape and hurt the impedance.4. Unshielded vs. ShieldedThis specific model (FD 810 P) is usually unshielded. If you have high electromagnetic interference (EMI) from big motors nearby, you might need the “CY” version (ÖLFLEX® CLASSIC FD 810 CY). The CY version has a copper braid shield. It stops noise. But the CY version is thicker and heavier. If you do not have heavy noise issues, the standard FD 810 P is easier to install.
