Is Your Production Line Stopping Because of Broken Cables?
You know the feeling. Everything is running smooth. The machines are moving fast. Then suddenly, the whole line stops. You check the control panel, and it’s an error code. You trace the wires and find it—the cable in the drag chain is cracked. The copper is exposed. Oil is leaking into the control box. This is a nightmare for any maintenance manager.Cheap cables crack under pressure. They get stiff in the cold. They swell up when they touch coolant. And when they break, they cost you more than just the price of a new wire. You lose hours of production. You pay for expensive repair technicians. You risk damaging the servo motor itself.You need a cable that doesn’t just survive. It needs to thrive in the toughest conditions. You need a cable built for continuous flexing, aggressive fluids, and heavy industrial abuse. This is not just a wire. It is the lifeline of your automation system.
The Ultimate 6-Core Solution for Servo Motors and Brakes
This cable is designed specifically for high-performance servo drives. It handles both the main power and the brake system in one single, tough jacket. We are talking about the German imported servo power supply + brake cable 6-core 4G 2.5 + 2×1.5 square mm shielded cable.Let’s break down what that means for you. The “6-core” part means you have all the wires you need in one place. You don’t need to run separate cables for power and brakes. This saves space in your drag chain and cuts down installation time. The “4G 2.5 + 2×1.5” is the size. You have four main power cores at 2.5 mm² and two smaller cores at 1.5 mm² for the brake or control signals.This specific build matches the high standards of Siemens and other major drive manufacturers. It fits perfectly into C-tracks and energy chains. It is built to handle the torque and tension of constant movement. If you are building a machine tool, a robotic arm, or a conveyor system, this is the cable you need.
Built with Real PUR Material for Maximum Life
Why do we use PUR (Polyurethane) for the jacket? Because standard PVC just isn’t tough enough. PVC gets brittle. It cracks when it bends too much. It gets soft and sticky when it touches oil.PUR is different. It is abrasion-resistant. It is cut-resistant. It is tear-resistant. If you drag this cable over sharp metal edges, it won’t split open. If you expose it to hydraulic oil or cutting coolant, it won’t dissolve.This jacket is specially formulated to be hydrolysis-resistant. That means water and steam won’t break it down. It is also microbe-resistant. Mold and bacteria won’t eat it. It handles UV light well, so if you have outdoor machinery, the sun won’t crack it.The temperature range is huge. It works perfectly from -40°C up to +80°C (and up to +90°C for fixed installs). Whether you are in a freezing cold warehouse or a hot factory floor, the cable stays flexible. It doesn’t get stiff in the cold, which means less stress on the connectors.
Shielded to Stop Electrical Noise
Electromagnetic interference (EMI) is a silent killer. It causes glitches in your servo drives. It makes sensors read the wrong data. It creates “ghost” signals that crash your PLC.This cable has a high-quality braided shield. We use tinned copper wires for the shield to prevent corrosion. The coverage is about 85% to 90%. This creates a Faraday cage around the cores. It keeps the noise out and keeps your signals clean.The shield is optimized for continuous flexing. Some shielded cables break the shield wire when they bend. Ours is stranded specifically to handle millions of bending cycles without snapping. This ensures your data transmission stays stable, even when the cable is twisting and turning in the drag chain.
Technical Specifications You Can Trust
We believe in transparency. Here are the hard numbers for this specific model:
- Conductor Material: 99.99% Oxygen-Free Copper (OFC). This gives you the best conductivity and less heat build-up.
- Stranding: Class 6 fine stranding (IEC 60228). The wires are made of many tiny strands, not one thick one. This makes it super flexible.
- Core Configuration: 4 x 2.5 mm² (Power) + 2 x 1.5 mm² (Brake/Control).
- Outer Diameter: Approximately 13.1 mm to 14.2 mm (depending on insulation thickness).
- Weight: Around 270 kg/km to 333 kg/km. It’s heavy because it uses real copper and real shielding, not cheap fillers.
- Bending Radius: The minimum bend is 7.5 times the outer diameter when moving. For fixed installs, it is 5 times. This tight bend radius means it fits in small energy chains.
- Bending Cycles: This cable can handle 10 million to 20 million cycles. Most standard cables fail at 1 million.
- Voltage Rating: 600/1000 V (0.6/1 kV). Safe for almost all industrial servo systems.
- Test Voltage: 4000 V AC. It is built to handle high-voltage spikes.
- Flame Retardancy: Self-extinguishing (IEC 60332-1-2). It won’t spread fire if it gets too hot.
- Halogen Free: Yes. If it burns, it doesn’t release toxic smoke. This is critical for safety in enclosed spaces.
Resistant to Everything in Your Factory
Your factory is a hostile environment. There is oil, grease, and lubricant everywhere. There are alkaline coolants and acidic cutting fluids.This cable laughs at those chemicals. We test it against DIN VDE standards for oil resistance. It passes the alcohol-free benzine and kerosene tests. It is largely resistant to oils and greases.If you use aggressive coolant emulsions, this cable won’t swell up. The jacket has low adhesion. It doesn’t stick to itself or other cables. This is vital for drag chains. If cables stick together, they get pinched and damaged. This cable slides smoothly, reducing friction and wear.It is also silicone-free. This is important if you paint your machines later. Silicone causes “fisheyes” in paint. Since this cable has no silicone, you don’t have to worry about ruining the finish on your equipment.
Perfect for Drag Chains and C-Tracks
The number one cause of cable failure is bad installation in a drag chain. If the cable is too stiff, it fights the chain movement. If it’s too loose, it gets crushed.This folding resistant drag chain PUR cable is designed to work with the chain, not against it. The overall wrapping inside the jacket reduces friction. The non-woven material binding keeps the cores round and prevents them from flattening under pressure.The torsion rating is ± 30° per meter. This means the cable can twist slightly without damaging the internal wires. This is common in robotic arms that rotate.The speed rating is up to 5 m/s. The acceleration is up to 50 m/s². If your machine moves fast and stops fast, this cable can keep up. It won’t snap back or whip around.
Easy to Install and Strip
Time is money. You don’t want to spend hours stripping wires. The outer jacket strips cleanly. It doesn’t leave a sticky residue. The inner insulation (TPE or HGI) also strips easily.The color coding is standard. The power cores are black with white number prints. The ground wire is green/yellow. The control cores are clearly marked (like BR1, BR2). This prevents wiring mistakes during installation.Because it is a shielded cable, you need to ground the shield correctly. We make this easy with a high-quality drain wire and braid that is simple to terminate.
