Stop losing money on cable failures in your moving machinery
You know the problem. You build a great machine. It runs fast. It works hard. But then, the cables inside the drag chain start to fail. The insulation cracks. The copper wires break. Your machine stops. You lose production time. Your maintenance team hates fixing wires in tight spaces. This happens because you used a standard cable that was never meant to move. Standard cables are for walls. They are not for motion. You need a cable that lives in the drag chain. You need a cable that bends, twists, and pulls without breaking. You need the German standard 18 core 0.5 sq mm high flexibility cable. This is not just a wire. It is a lifeline for your automation equipment. It solves the headache of downtime. It is built for the tough life inside a drag chain.
What makes this 18G 0.5 sq mm cable special?
This cable is a power and control hybrid. It does two jobs. It carries power to your motors. It also carries control signals to your sensors. The “18G” means it has 18 cores. The “0.5 sq mm” is the size of each copper wire. This size is the sweet spot. It is small enough to fit in tight chains. It is big enough to carry the load.The conductor is bare copper. But it is not a solid rod. It uses IEC 60228 Class 5 stranding. This means it is made of many tiny wires twisted together. This is why it is so flexible. If you bend a solid wire, it snaps. If you bend this stranded wire, it moves. It flows with the motion of the machine.The sheath material is special. We use high-quality PVC or PUR (Polyurethane). Why does this matter? Because your factory floor is dirty. There is oil. There is coolant. There is dust. A cheap cable absorbs this oil. The insulation swells. It gets soft. It falls apart. Our cable resists oil. It resists chemicals. It stays strong even in a harsh environment. It is also PWIS-free. This means it does not contaminate sensitive areas like food processing or pharmaceutical lines.
Incredible bending strength and torsion resistance
Let’s talk about the bending radius. This is the most important number for drag chains. If you bend a cable too sharp, you kill it. For this 18 core cable, the outer diameter is about 10.5 mm.When the cable is fixed, you can bend it to 4 times the diameter. That is about 42 mm. That is very tight. But the real magic happens when it moves.For dynamic movement in a drag chain, the minimum bending radius is 15 times the diameter. That is around 157 mm. But for continuous flexing, we recommend 100 mm to 150 mm depending on the specific 810 P series you pick. The ÖLFLEX® FD CLASSIC 810 P is famous for this. It can handle small bending radii. It saves space in your design. You can use a smaller drag chain. This saves weight and cost.Torsion is the twisting force. Many machines twist the cable as they move. Standard cables hate this. They untwist and break. This cable is built for torsion. It can handle +/- 150 degrees per meter. It can do this for thousands of cycles. It does not need to hang loose. You can fix it at both ends. It will not twist into a knot.
Built to last 1 million cycles
You need reliability. You do not want to change cables every month. This cable has a tested life cycle. It can handle more than 1 million bending cycles. In some high-end versions, it can even reach 10 million cycles.The temperature range is wide. It works from -40°C to +80°C. If you need higher heat, we have versions that go to +105°C. This covers almost all industrial environments. From cold storage warehouses to hot steel mills.The copper content is high. We use 86.4 kg of copper per kilometer of cable. This means low resistance. Low resistance means less heat. Less heat means longer life. The test voltage is 4 kV. This shows the insulation is thick and strong. It prevents short circuits even when the cable rubs against the steel link of the drag chain.
Perfect fit for your steel or plastic drag chain
This cable fits perfectly with standard drag chains. Whether you use steel or plastic, this cable slides smoothly. We recommend a bending radius of 10 times the cable diameter for the drag chain itself. So for this 10.5 mm cable, use a chain with a radius of at least 105 mm.The drag chain protects the cable. The cable protects your signal. Together, they stop the “tank chain” noise. The cable is quiet. It does not squeak. It runs smooth at speeds up to 50 meters per minute. The noise level stays below 68 decibels. Your factory stays quiet.You can use this in robot arms. You can use it in CNC presses. You can use it in automated warehouses. It works in welding applications. It resists the sparks and the slag. It is flame retardant. If there is a fire, it does not spread the flame. It is safe for your building.
Easy to install and identify
We know installation takes time. We make it easy. The outer sheath is grey. We print numbers on the cores. This follows VDE 0293 standards. Your electricians will love this. They can identify wire 1, wire 2, and so on. No guessing games. No multimeter needed for every connection.The outer diameter is 10.5 mm. The weight is about 187 kg per kilometer. It is heavy enough to stay in place. It is light enough to not weigh down your moving part. This reduces the inertia of your machine. Your motors use less energy to move the cable. You save electricity.We offer different shielding options. If you have high EMI (electromagnetic interference), we add a braided shield. This stops noise from welding machines or VFDs from messing up your sensor signals.
