Is your machinery downtime costing you a fortune?
You know the feeling. You just fixed the production line, and two weeks later, the cables in the drag chain start to crack. The insulation breaks, the cores snap, and suddenly the whole system stops. You lose money every minute the machines are silent. You need a cable that moves, bends, and twists without giving up. You need a cable built for the real world, not just for a catalog.Most “flexible” cables on the market are not actually flexible enough. They are too stiff, too heavy, or they break after a few thousand cycles. You need a solution that lasts for millions of movements. This is where the German-made ÖLFLEX CLASSIC FD 810 18G1.5 comes in. It is not just a wire; it is a heavy-duty tool designed for your toughest jobs.
What makes the ÖLFLEX CLASSIC FD 810 special?
This cable is part of the “Core Line” from LAPP. It is a time-tested, reliable, and cost-effective solution. The “FD” in the name stands for “Flexible Drag chain.” It is specifically engineered for power chains and moving machine parts.Unlike standard installation cables (like the ÖLFLEX CLASSIC 110), the FD 810 is built for motion. It can handle 5 million alternating bending cycles. It can travel up to 10 meters in a drag chain. The outer sheath has a special low-adhesion surface. This means the cables slide against each other easily inside the chain. They do not get stuck or wear out from friction.It is flame-retardant according to IEC 60332-1-2. It is also PWIS-free, which means it does not release particles that could harm sensitive electronics in clean rooms.
Technical Specifications: The numbers you need to know
Here is the hard data for the 18G1.5 version. These numbers prove why this is a top-tier product.
Electrical Characteristics
- Rated Voltage: U0/U = 300/500 V AC. This is the standard for most industrial control systems.
- Test Voltage: 4 kV. We test it at high voltage to ensure safety.
- Conductor Resistance: 13.3 Ω/km. This is very low resistance for a 1.5 mm² cable. It means less heat and more power efficiency.
- Current Carrying Capacity: While exact amps depend on installation, a 1.5 mm² copper core typically handles around 18A in open air.
- Number of Cores: 18 Cores (18G).
- Conductor Cross-Section: 1.5 mm².
- Core Identification: Numbers printed on the core insulation (Black with white numbers). This makes wiring easy.
- Screening: Unscreened. If you need EMC protection, you must look at shielded versions like the S 86 C series.
Mechanical & Physical Properties
- Conductor Material: Bare copper. It is finely stranded (Class 6 according to VDE 0295). This gives it extreme flexibility.
- Insulation Material: PVC (Polyvinyl Chloride). It is flame-retardant and oil-resistant.
- Sheath Material: PVC (Grey, RAL 7001).
- Outer Diameter: 15.6 mm. This is a compact size for an 18-core cable.
- Weight: 470 kg/km. It is light enough for dynamic applications but heavy enough to be durable.
- Copper Index: 259 kg/km. This shows the high amount of pure copper used.
- Minimum Bending Radius:
- Fixed installation: 4 x Outer Diameter (approx. 62 mm).
- Moving/Flexing: 4 x Outer Diameter (approx. 62 mm). Note: Some older cables need 10x or 15x, but FD 810 is optimized for tight bends.
- Temperature Range: -40 °C to +80 °C. It works in freezing cold and hot factory environments.
- Oil and Chemical Resistance: Yes. It resists oils, ozone, and UV rays (with protection).
Where should you use this cable?
You should use this cable anywhere something moves. If the cable is static (fixed in a wall), you can use a cheaper cable. But if it moves, you need the FD 810.
Drag Chains and Cable Chains
This is the #1 use case. The cable is pulled in and out of the chain thousands of times. The low-adhesion sheath prevents the cables from tangling. The fine stranding of the copper prevents the metal from fatiguing and snapping.
Automation and Robotics
In robotic arms, the cables at the joint face constant stress. The FD 810 handles this stress. It is perfect for assembly lines, pick-and-place machines, and welding robots.
Measuring and Control Circuits
Because it has 18 cores, you can send power and multiple signals through one cable. This saves space. It is great for conveyor belts, packaging machines, and CNC machines.
Indoor and Outdoor Use
It works well in damp or wet interiors. For outdoor use, you must provide UV protection (like a conduit or cable tray) because standard PVC can degrade in direct sunlight over time.
How does it compare to other cables?
Let’s look at the competition and see why the FD 810 wins.
vs. ÖLFLEX CLASSIC 110 18G1.5
The CLASSIC 110 is a great general-purpose cable. But it is not made for high dynamic flexing. The 110 needs a bending radius of 10x to 15x the diameter when moving. The FD 810 only needs 4x. The FD 810 also has a special fleece wrapping and a different sheath compound to reduce friction. If you put a CLASSIC 110 in a drag chain, it will fail fast.
vs. Shielded Cables (like S 86 C)
The S 86 C series has a copper braid screen. This is great for stopping electromagnetic interference (EMI). But it is heavier, thicker, and more expensive. If your application does not have heavy EMI noise (like simple motor control), the unshielded FD 810 is a better, cheaper, and lighter choice.
vs. Solar Cables (like TommaTech)
Solar cables are built for UV resistance and high DC voltage. They are not designed for fine stranding or flexing. They are stiff. Do not use solar cables in drag chains; they will break.
vs. LiYY Data Cables
LiYY cables are for data signals, not power. They have very thin cores. The FD 810 has 1.5 mm² cores, which can carry real power to drive actuators and sensors.

Frequently Asked Questions
Can I use this cable for outdoor applications?Yes, but you must protect it from direct UV sunlight using a cable duct or tray. The PVC sheath is weather-resistant but not UV-stable forever.Is this cable suitable for welding machines?For welding, you usually need specific welding cables with rubber insulation. The FD 810 is PVC. PVC melts at high heat. Do not use it directly on welding torches, but it is fine for the control circuits of the welding machine.What is the difference between “Core Line” and “Extended Line”?LAPP has three lines: Basic, Core, and Extended.
- Basic Line: Standard cables.
- Core Line (FD 810): Highly flexible, for dynamic use, flame-retardant. This is the “sweet spot” for most industrial use.
- Extended Line: For extreme conditions (extreme oil, extreme abrasion).
How many cores does this cable have?It has 18 cores, each with a cross-section of 1.5 mm². It also includes a protective earth (ground) conductor.
