Your Cable Breaks Too Often? We Have the Fix.
You know the problem. You run a factory or a workshop. You have robotic arms moving all day. Or maybe you have a CNC machine cutting metal. The cables inside the drag chain keep breaking. It happens at the worst time. The machine stops. You lose money. Your team has to open the chain. They find a cracked wire. They replace it. Two weeks later, it breaks again.Why does this happen? Standard wires are too stiff. They cannot bend millions of times. They get hot. Oil and coolant eat the jacket. Electrical noise messes up your signals. This causes errors in your production. It is frustrating. You need a cable that stays strong. It must move freely without twisting. It must block noise. And it must last for years.We have the solution. It is the German-made 4-core 0.34 sq mm shielded high-flexibility drag chain cable. We call it the FD CY 4×0.34 mm. This is not a cheap copy. This is real engineering. It is built for the toughest jobs. It solves the pain of downtime. It fixes the pain of constant maintenance.
What Makes This Cable Special?
This cable is a beast in a small package. It is a 4-core cable. This means it has 4 wires inside. Each wire is 0.34 sq mm. This size is perfect for control signals and low power. It fits in tight drag chains. But it is strong.The “FD CY” part is important. It stands for a specific German standard. This standard means the cable is “highly flexible.” It uses a special copper alloy. The wires are very thin. They are twisted in a special way. This lets the cable bend sharp corners. It does not get tired.It is “shielded.” This means it has a metal braid around the wires. This braid stops noise. It keeps your signals clean. Other machines won’t mess up your data. This is critical for sensitive electronics.
Technical Specs You Need to Know
We believe in being honest. Here are the real numbers. You can compare these to your old cables.
Flexibility and Bending
This is the most important part. A stiff cable dies fast. This cable is different.
- Bending Radius (Fixed): You can bend it to 4 times its outer diameter. It stays safe when not moving.
- Bending Radius (Moving): When it moves, you can bend it to 7.5 times its diameter. This is very tight. Most cables need 10x or 12x. This saves space.
- Bending Cycles: It can bend more than 10 million times. Yes, million. Your machine will be old before this cable breaks.
- Speed: It moves fast. It handles speeds up to 5 meters per second when coasting. It handles 8 meters per second if it supports itself.
Electrical Power
- Voltage: It works at 300/500 Volts. Some versions go to 600/1000V. Check with us.
- Test Voltage: It is tested at 2000V to 3500V. It is safe.
- Conductor: The core is Class 6 fine wire. It is not solid copper. It is many tiny wires. This is why it bends so well.
- Shielding: The shield covers more than 65% of the wire. It blocks electromagnetic interference (EMI).
Physical Build
- Outer Jacket: It uses PUR (Polyurethane). This is better than PVC. PVC gets stiff in cold. PUR stays soft.
- Jacket Colors: We have Grey (RAL 7000), Black (RAL 9005), and Orange (RAL 2004).
- Temperature: It works from -40°C to +70°C (fixed). When moving, it is -5°C to +70°C. It handles heat well.
- Weight: It is light. A 4-core version is about 55 to 65 kg per km. This is light for the quality.
Resistance
- Oil and Chemicals: It resists oil, coolant, and grease. This is vital for CNC machines.
- UV and Ozone: The jacket resists sunlight. You can use it outside.
- Flame Retardant: It passes IEC 60332-1-2. It does not burn easily. It is self-extinguishing.
- Halogen-Free: It is safe. No toxic smoke if it burns.
Where Do You Use This Cable?
You can use this cable anywhere things move. It is a “drag chain cable.” It is also a “towline wire.” Here are the best spots:
Industrial Robots
Robot arms move fast. They twist and turn. Standard wires snap at the elbow. This FD CY cable moves with the arm. It carries power and data to the gripper. It does not tangle.
CNC Machines and Lathes
The cutting tool moves on X, Y, and Z axes. The cable goes back and forth. Coolant splashes on it. Metal chips fly. This cable resists the chips. It resists the coolant. It keeps the machine running.
Automated Assembly Lines
Conveyor belts move products. Sensors read barcodes. Motors drive belts. This cable connects everything. It handles the constant vibration. It blocks noise from the big motors. This stops false signals.
Cranes and Hoists
Heavy loads move up and down. The cable stretches and swings. It needs to be strong. The PUR jacket handles the abrasion. The steel shield in the chain won’t cut it.
Outdoor Equipment
If you have solar trackers or outdoor cameras, this cable works. The UV protection stops the sun from cracking the jacket. The water resistance keeps the inside dry.
Why Buy This German-Style Cable?
You might see cheaper cables online. They break in 3 months. You pay for the part. You pay for the labor to install it. You pay for the lost production. The cheap cable costs you more in the long run.This cable costs more upfront. But it lasts 5 times longer. You buy it once. You forget about it. Your maintenance team is happy. Your boss is happy because the machines run 24/7.It meets all the hard standards. It has UL and CUL marks. It follows VDE rules. It is RoHS compliant. You can sell your machine to Europe or the USA with this cable inside. It passes inspection.We can customize it. Do you need more cores? We can do 2, 3, 5, or up to 25 cores. Do you need a different color? We can do it. Do you need a special length? We cut it to size. We are a factory. We are not just a trader. We control the quality.
