Stop Cable Failures in Your Factory. We Make the Toughest Servo Cables for Your Robots.
Do you have problems with cables breaking in your drag chains? Is downtime costing you too much money? We know how frustrating it is when a cable snaps and stops your whole production line. You need a cable that bends millions of times without cracking. You need a cable that resists oil, dust, and heat.
We are a factory that specializes in high-quality German-style cables. We make the SAB servo cable, 6-core shielded power cable, brake cable, cable chain, PUR 4G2.5+(2*1.5). We build these cables to last. They work perfectly in harsh environments. If you need a custom solution, ask us for a quote today. Let us solve your cable problems.
What is this Special Cable Made Of?
This is not a standard wire you buy at a local shop. This is a heavy-duty industrial cable. It is designed for servo motors and robot arms. The “PUR” part is very important. PUR stands for Polyurethane. It is a special jacket material. It is much stronger than standard PVC.
The structure is 4G2.5+(2*1.5). Let me break this down simply:
- 4G2.5: This means there are 4 main power cores. Each core is 2.5 square millimeters in size. These carry the electricity to run your motor.
- +(2*1.5): This means there are 2 extra smaller cores. Each is 1.5 square millimeters. These are often used for the brake or holding circuit.
- 6-core: In total, including the power, ground, and brake wires, we have a robust 6-core setup.
- Shielded: We wrap the inner wires in a metal braid (usually tinned copper). This stops electrical noise from messing up your signal.
We use high-purity copper for the conductors. This ensures low resistance and less heat. The insulation is also special. It can handle high voltage spikes. This is common in servo drive systems.
Why Use PUR Jacket Instead of PVC?
You might ask, “Why PUR?” The answer is simple. PVC gets stiff and cracks. PUR stays flexible. In a factory, things get dirty. Oil, coolant, and metal shavings are everywhere.
Standard PVC cables absorb oil. The oil makes the cable swell up. Then it gets brittle and breaks. Our PUR 4G2.5+(2*1.5) cable is different. It resists oil completely. It also resists water and chemicals.
Another big factor is temperature. Standard cables work in an office. They fail near a hot motor. Our cable can handle a wide temperature range. It works in cold freezers and hot foundries. It does not get hard in the cold. It does not melt in the heat. This is why it is the best choice for cable chain applications where the cable is constantly moving.
Perfect for Drag Chains and Robot Arms
Imagine a robot arm moving up and down all day. The cable in its “elbow” bends thousands of times. If the cable is stiff, it will snap. Our SAB servo cable is built for this. We call this “high flex” or “continuous flex” capability.
We design the lay of the wires inside. The wires are not just solid chunks of copper. They are made of many tiny strands. This is called “stranded” copper. It acts like a rope, not a stick. It bends easily without breaking the metal inside.
This cable is also great for cable chain (also called drag chains or energy chains). In a drag chain, cables rub against each other. Friction creates heat and wear. Our cable has a smooth outer jacket. It slides easily against other cables. It reduces friction inside the chain. This makes the whole system run smoother and quieter.
The Importance of Shielding (EMI/RFI Protection)
Electrical noise is a silent killer in automation. Servo motors create a lot of electromagnetic interference (EMI). If your cable is not shielded, this noise travels to your controller. This can cause errors. Your machine might stop for no reason. Or it might move slightly when it should be still.
Our 6-core shielded power cable fixes this. The shield acts like a cage. It catches the noise and sends it to the ground. It keeps the signal clean. This is critical for precision machines. CNC machines, injection molders, and packaging robots all need clean power.
We use a high-coverage braid shield. Some cheap cables only cover 60% of the wire. Ours covers much more. We also add an aluminum foil layer under the braid. This gives you double protection. You get stable data and stable power. No glitches. No downtime.
Technical Specifications You Can Trust
When you buy from us, you get exact specs. We do not guess. Here is what you can expect from our standard German SAB style cable:
- Voltage Rating: 600V / 1000V. This covers almost all industrial servo systems.
- Temperature Range: -40°C to +125°C. It works in extreme cold and heat.
- Bending Radius: 8x to 10x the cable diameter. It can bend very tightly without damage.
- Conductor Material: Bare copper or Tinned Copper (for extra corrosion resistance).
- Insulation Material: Special PUR or TPE mix. Halogen-free and flame retardant.
- Shielding: Tinned Copper Braid + Aluminum Foil.
- Core Colors: Standard colors (Black, White, Red, Green/Yellow) or custom numbers printed on white cores.
- Certifications: CE, RoHS, UL (if requested). We can make cables that meet German VDE standards.
We can also change the specs. Need a thinner cable? Need more cores? We can do it. We are the factory. We make what you need.
Where Can You Use This Cable?
This cable is not just for one machine. It is versatile. You can use it in many places. Here are the top scenes:
- CNC Machines: Connect the servo motor to the drive. The shielding stops noise from affecting the computer.
- Robotic Welding: The cable resists sparks and spatter. The PUR jacket is tough against physical damage.
- Automated Assembly Lines: In long drag chains, the cable moves fast. It handles millions of cycles.
- Food and Beverage: We can make the PUR jacket “food grade.” It resists washdowns and cleaning chemicals.
- Outdoor Equipment: The UV-resistant jacket stops the sun from cracking the cable.
- Elevators and Cranes: The cable is strong enough to hang vertically for long distances.
If you have a special project, tell us. We have made brake cable assemblies for elevators and servo cables for underwater robots. We can solve your specific problem.
Why Buy From Us? We Are Your Partner, Not Just a Seller.
There are many cable sellers. But few are factories that care about quality. We have been making cables for years. We know that a bad cable costs more than the price of the wire. It costs you lost production.
When you order from us, you get:
- Free Samples: We send you a sample so you can test it in your machine first.
- Custom Printing: We print your logo or text on the cable jacket.
- Fast Lead Time: We make the cable in 3 to 10 days. We do not make you wait weeks.
- Technical Support: If you are not sure which cable to pick, our engineers help you.
- Strict QC: We test every batch. We check the copper purity, the shielding, and the jacket thickness.
We want to be your long-term supplier. We want you to come back for every order. Quality is our only marketing strategy.
