Is your machinery cable failing too soon?
You know the problem. Your production line is running fast. The robot arm is moving. The cable carrier (drag chain) is snapping back and forth. Then, suddenly, the machine stops. You check the cable. The outer jacket is cracked. The copper inside is broken from metal fatigue. Or maybe the cable got stiff and jammed in the chain, causing a tear.This downtime costs you money. Every hour a machine is down, you lose profit. Standard cables do not work in moving parts. They are too stiff. They crack when bent. They swell when they touch oil or coolant.You need a cable that moves like a snake but protects the signal inside. You need the ÖLFLEX® CLASSIC FD 810. This is not just a wire. It is a high-performance tool for your machine. Specifically, the 34-core 1 sq mm drag chain cable (Part No. 0026141) is built for heavy-duty motion. It resists oil. It resists bending stress. It keeps your factory running.
What makes this cable special?
This cable is part of the “Core Line” from Lapp. This means it sits in the middle of the performance range. It is better than the basic cheap stuff, but it is not the most expensive “Extended” line. It is the sweet spot for most industrial machines.The FD 810 is designed for “flexing.” This means it is made to move. The conductors inside are made of extra-fine wires (Class 6 flexibility). Imagine a rope made of many tiny threads versus a thick solid stick. The rope bends easily. The stick snaps. This cable uses the “rope” design.The outer sheath is Polyurethane (PUR). Why does this matter? Because factories are dirty. There is oil, grease, and cutting fluid everywhere. Standard PVC gets soft and sticky in oil. PUR stays tough. It resists abrasion. It resists chemicals. The cable jacket is also shielded with a tin-plated copper braid. This stops electromagnetic interference (EMI) from messing up your sensor signals.
Technical Specifications: The Numbers You Need
When you buy 34-core 1 sq mm drag chain cable, you need to know the exact size. Here are the hard facts for Part No. 0026141:
- Part Number: 0026141
- Conductor: 34 cores (G)
- Cross-Section: 1.0 mm²
- Outer Diameter: 18.9 mm (This is important for your cable carrier size!)
- Weight: 595 kg/km
- Copper Content: 326.4 kg/km
- Nominal Voltage: 300/500 V (U0/U)
- Test Voltage: 4000 V
- Bending Radius:
- Fixed installation: 4 x outer diameter (approx. 75 mm)
- Flexible use: 7.5 x outer diameter (approx. 142 mm)
- Note: Always check your drag chain manufacturer’s radius. The cable radius must match the chain radius.
- Temperature Range:
- Flexing: -5°C to +70°C
- Fixed: -40°C to +80°C
- Bending Cycles: 5 million cycles (This is a lot of movement!)
- Approvals: UL/CSA AWM Styles, VDE, IEC 60332-1-2 (Flame retardant)
Where do you use this cable?
You should use this highly flexible drag chain cable in any place where wires move. Do not use it for fixed wiring in a wall—that is a waste of money. Use it where the action is.Here are the best application scenarios:
- CNC Machine Tools: The axis moves constantly. The cable needs to bend millions of times.
- Robot Arms: The elbow and wrist joints need a cable that twists and turns without breaking.
- Assembly Lines: Conveyor belts that move products need power and signal cables that flex with the motion.
- Port Cranes and Hoists: These cables are exposed to the weather and heavy load movement.
- Wood and Stone Processing: These environments have a lot of dust and debris. The abrasion-resistant jacket protects the core.
If your machine has a “cable carrier,” “energy chain,” or “drag chain,” this is the right cable. It is also great for clean room applications if you need low particle emission.
How does it compare to other cables?
Lapp Group divides their drag chain cables into three lines. Knowing this helps you save money.
- Basic Line: Cheapest. Good for slow machines or short travel distances. Not for high speed.
- Core Line (FD 810): The middle choice. Good flexibility. Good oil resistance. Handles long travel and high acceleration. This is the 0026141 model.
- Extended Line: Most expensive. For extreme stress. Very high temperature range. Halogen-free.
For 90% of standard factory automation, the Core Line FD 810 is enough. You do not need to pay extra for the Extended line unless you have extreme heat or special fire safety rules.Also, look at the construction. This cable has:
- Fine-wired copper: Class 6 stranded.
- PVC Insulation: Colors with numbers for easy identification.
- Fleece Wrapping: Protects the insulation from friction.
- PVC Inner Sheath: Holds the cores together.
- Tinned Copper Braiding: 85% coverage for shielding.
- PUR Outer Sheath: Grey (RAL 7001), matte finish. Very tough against oil.
Why buy this specific part (0026141)?
You need 34 cores. That is a lot of signals in one cable. If you try to put 34 single-core wires in a chain, it will be a mess. It takes too long to install. This multi-core cable solves that. It groups all 34 wires into one round, strong unit.The 1.0 sq mm size is perfect for control signals and low-power actuators. It is not too thick to bend, but it carries enough current for sensors and solenoids.The oil resistance is critical. In a machine shop, coolant leaks happen. If the cable absorbs oil, the insulation swells and cracks. The PUR jacket on the FD 810 prevents this. It keeps the moisture and chemicals out.
