Your Cables Keep Breaking? Stop The Downtime Now.
You know the feeling. You set up a machine, install the cables, and everything runs smooth for a week. Then, the movement starts. The cables in the drag chain twist, bend, and rub against each other. Soon, the jacket cracks. Copper wires show through. Short circuits happen. Your production line stops. You lose money.This is the number one pain point for engineers and maintenance teams. Standard PVC cables get stiff in the cold. They crack when bent. They melt when they touch oil or grease. You need a cable that moves like a snake but is tough like a tank. You need a cable that does not just survive but thrives in harsh conditions.We bring you the solution directly from German engineering: the LEONI 2-core 2.5mm² power cable reinforced with PUR fine wire. This is not just a wire. It is a high-performance power transmission line built for extreme movement and rough environments.
What Makes This LEONI PUR Cable Different?
You might ask, why PUR? Why not standard PVC? The answer is simple: physics and chemistry.PVC is cheap, but it has limits. When it gets cold, it becomes hard and brittle. When it gets hot, it gets soft. Oil and chemicals eat it alive. But Polyurethane (PUR) is a different beast.This LEONI cable uses a special industrial-grade PUR jacket. Think of it as a rubber that is engineered in a lab. It has memory. It bends without kinking. It resists abrasion like no other material. If you drag this cable over concrete, it will not scratch easily. If you spill hydraulic oil on it, the oil just slides off.The “fine wire” construction means the copper inside is made of many tiny strands, not one thick solid wire. This makes the cable super flexible. It can bend in a tight space without stressing the metal. This is why we call it “bend-resistant.” It can handle millions of motion cycles.
Technical Specs You Can Trust
We do not hide behind fancy words. Here are the real numbers that matter for your project:
Core and Conductor Details
- Conductor Size: 2.5 square millimeters (approx. 14 AWG). This is the sweet spot for power. It is thick enough to carry current but thin enough to stay flexible.
- Core Configuration: 2-Core. You get two insulated conductors inside one jacket. Perfect for single-phase power or DC circuits.
- Conductor Material: Fine-stranded electrolytic copper (Cu-ETP). High purity means less resistance and less heat.
- Stranding: Class 5 flexible stranding according to VDE 0295. This means the copper is made of many thin wires twisted together for maximum flexibility.
Jacket and Insulation
- Jacket Material: Polyurethane (PUR).
- Jacket Color: Usually black or orange (customizable).
- Insulation Material: Special PUR or Foamed PE blends depending on the exact model (like L45467 series).
- Halogen Free: Yes. If there is a fire, it does not release toxic smoke. This is critical for public buildings and subways.
- Flame Retardant: Meets IEC 60332-1-2 standards. It is hard to burn.
Performance Limits
- Rated Voltage: Up to 600V (some versions 0.6/1kV). Safe for most industrial machinery.
- Operating Temperature: -40°C to +90°C. It works in freezing cold warehouses and hot factory floors.
- Bending Radius: This is the king of specs.
- Fixed installation: 4 times the cable diameter.
- Moving installation: 10 times the cable diameter.
- This tight bend radius is why it fits in small drag chains.
- Tensile Strength: Can handle significant pulling force during installation without stretching or breaking.
- Oil and Chemical Resistance: Fully resistant to oils, greases, solvents, and coolants.
Where Should You Use This Cable?
This cable is a workhorse. You can use it almost anywhere there is movement or danger. Here are the top scenarios:
Industrial Automation and Robotics
Robots move fast. Their arms twist and turn. The cables inside the robot arm go through constant stress. A standard cable would snap in a month. This LEONI PUR cable can last for years in a robotic arm. It is also perfect for servo motors and encoder connections.
Drag Chains (Cable Carriers)
If you have a CNC machine or an automated assembly line, you have a drag chain. The cable inside the chain moves back and forth all day. This cable is specifically designed for “continuous flexing.” The PUR jacket has low friction, so it slides smoothly inside the chain links without getting stuck or worn down.
Outdoor and Renewable Energy
Solar panels track the sun. Wind turbines twist in the wind. These cables sit outside in UV rays, rain, and snow. The PUR jacket has excellent UV resistance. It does not crack from sunlight. It is also water-resistant (IP65/IP67 ratings available for specific types), making it great for outdoor control boxes.
Marine and Shipbuilding
On a ship, everything vibrates. Engines rumble. Waves crash. Cables need to handle vibration and potential oil leaks. This cable meets marine standards (like IEC 60092). It is flame-retardant and does not release halogens, which is a strict safety rule on ships.
Electric Vehicles and Charging Stations
With the rise of EVs, high-quality cables are in demand. While this is a 2.5mm² cable (not the massive high-voltage orange cable), it is perfect for auxiliary power in EVs, like connecting the battery to the air conditioning compressor or DC-DC converters. It handles the heat and vibration of the engine bay well.
