Your Machines Are Fast. Why Is Your Cable Slow?
You have a problem. Your production line runs at high speed. Your robotic arm moves thousands of times a day. But your cable keeps breaking. The jacket cracks from oil. The signal drops because of noise. You stop the machine to fix the wire. You lose money every minute.Standard cables are not built for this. They are too stiff. They break when bent. They get eaten by coolant oil. They pick up electrical noise from the motors next to them. This causes errors in your control system. It is frustrating.You need a cable that moves as fast as your machine. You need a cable that ignores oil and noise. You need a cable built for the drag chain. This is not just a wire. It is a lifeline for your automation system.
What Makes This 10-Core PUR Cable Different?
This is not a standard wire. It is a specialized imported cable designed for harsh industrial life. We combine signal and power in one strong jacket. The structure is specific: 8 cores of 0.2 sq mm twisted pairs for data, and 2 cores of 0.3 sq mm for power.The outer jacket is PUR (Polyurethane). This is not cheap PVC. PUR is tough. It resists oil, cutting fluids, and abrasion. It stays flexible in cold and hot environments. We use a special mix that handles -20°C to +80°C when moving. If fixed, it handles -40°C to +90°C.The most important part is the double shielding. We wrap every twisted pair in foil. Then we wrap the whole cable in a tinned copper braid. This stops EMI (Electromagnetic Interference). It stops external noise from getting in. It stops your signal from leaking out. Your data stays clean. Even next to big servo motors.

Construction Details
The 8 cores of 0.2 sq mm are arranged in twisted pairs. This cancels out noise. Each pair has a specific lay length. This makes the cable very flexible. The 2 cores of 0.3 sq mm provide stable power for sensors or small lights. We use a drain wire inside the shield. This makes grounding easy and fast. You do not need to strip the jacket to ground the shield.
Where To Use This Cable?
This cable fits specific high-stress jobs. Do not use it for house wiring. Use it where things move.
Robotics & Articulated Arms
Multi-axis robots need cables that twist and turn. This PUR drag chain cable handles torsion loads. It does not kink. It is perfect for the “elbow” or “wrist” of a robot.
CNC Machine Tools
Machine tools use coolant and oil. Standard PVC gets soft and sticky in oil. PUR jacket resists this. The double shielded design stops the VFD (Variable Frequency Drive) noise from messing up encoder signals.
Automated Assembly Lines
Conveyors and festoon systems need long cables that drag. This cable has high tensile strength. It does not stretch. The twisted pair design ensures data integrity over long runs (up to 100 meters).
Servo Motor Encoders
Servo motors need precise feedback. If the signal is noisy, the motor jerks. The individual foil shields on the pairs prevent crosstalk. This gives smooth motion control.
Why “Double Shielded” Is Critical For You
You might ask, “Why not just single shield?” Let me explain.In a factory, you have heavy machinery. Welders. Big motors. VFDs. These create a storm of electromagnetic noise.A single shield protects the whole cable. But noise can still jump between the pairs inside the cable. This is called “crosstalk.” It makes your data slow or corrupt.Our double shielded design (F/UTP or S/FTP style) fixes this.
- First Layer: Each pair of 0.2mm wires has its own foil shield. They are isolated from each other.
- Second Layer: A copper braid wraps everything. This blocks outside noise.
It is like having a lock on the door (braid) and a safe inside the room (foil). Your data is 100% safe. This is vital for imported cable standards like CE, RoHS, and REACH. We meet these rules so you can sell your machine globally.
The PUR Jacket Advantage
Let’s talk about the jacket. Most cables use PVC. PVC is okay for indoors. But in a factory? PVC fails.PUR (Polyurethane) is the upgrade.
- Abrasion Resistant: It slides against metal tracks without wearing out.
- Hydrolysis Resistant: It laughs at water and steam.
- Low Adhesion: It does not stick to itself or other cables.
- Flame Retardant: It meets safety standards for public buildings.
If your cable is in a drag chain, it rubs against the plastic links. It bends back and forth millions of times. A PVC jacket cracks in weeks. A PUR jacket lasts for years. We test our cables for 5 million bending cycles. This is real reliability.
Installation Tips for Long Life
To get the best performance, follow these simple rules.
Bending Radius
Do not bend the cable too sharp. The minimum radius is 7.5 times the outer diameter when moving. If you bend it sharper, you break the copper strands inside.
Fixing the Cable
Use cable glands at both ends. Ground the drain wire to the gland. This creates a 360-degree shield connection. It stops noise from entering the system.
Separation
Keep high-voltage power cables away from this signal cable. Even with shielding, too much noise can overwhelm the shield. Give them space in the track.
Frequently Asked Questions
Q: Can I use this for outdoor use?A: Yes. The PUR jacket is UV resistant and water-tight. But if it is not moving, direct sunlight over years will harden any plastic. For moving parts outdoors, it is perfect.Q: What is the maximum length?A: We supply up to 100 meters per roll. For longer runs, we can join rolls. But for high-speed data (like RS485), keep the run under 1200 meters without a repeater.Q: Is the 0.3 sq mm power enough?A: It depends. 0.3 sq mm (approx 22 AWG) handles about 5-7 Amps. It is great for sensors, encoders, and small brakes. For big motors, you need a separate power cable.Q: Do you have different colors?A: Yes. Black is standard. We can do Green/Yellow for ground, or Orange for identification. We can also print numbers on the cores for easy wiring.
