Is your cable breaking down?
You have a big problem. Your machines move. They bend. They twist. And your cables are cracking. You see the outer jacket splitting open. The copper wires inside are breaking. Signal loss happens. Power cuts out. You have to stop the whole production line just to change a wire. This costs you money. It costs you time. It is frustrating.Standard PVC cables get stiff in the cold. They crack when bent. They melt when oil touches them. You need a cable that moves as much as your machine does. You need a cable that lasts. You need the 12-core 1.5 square millimeter PUR sheathed copper core power cable from the 855P series. This is not just a wire. It is a heavy-duty solution for drag chains and moving parts.
What makes this cable special?
This cable is built for tough jobs. It has 12 separate cores inside. Each core is 1.5 square millimeters in size. This is the perfect size for control signals and low-voltage power. The cores are made of high-purity copper. This means very low resistance. The electricity flows easily. The cable does not get hot.The outer jacket is the real hero. It is made of PUR (Polyurethane). PUR is much better than standard plastic. It is extremely flexible. You can bend it, twist it, and pull it. It will not crack. It resists oil and grease. If your factory floor is oily, this cable is safe. It also handles cold very well. It stays soft even in freezing temperatures. It is abrasion-resistant. If it rubs against metal, it does not wear out quickly.This is the 855P series. This series is famous for high flexibility and long life. It is designed specifically for drag chains. The cable can handle millions of bending cycles. It is the “set it and forget it” solution for your automation systems.

Construction Details
Let’s look inside the cable. Quality matters. We do not cut corners.
The Copper Core
We use oxygen-free copper. Why? Because it conducts electricity better than regular copper. It does not corrode easily. Each core has many thin strands of wire twisted together. This is called “stranded” construction. Solid wire breaks if you bend it. Stranded wire flexes. It moves with the machine. The 1.5mm² area gives you enough copper to carry power for sensors, relays, and small motors without voltage drop.
The Insulation
Each copper core is wrapped in its own insulation layer. This prevents short circuits. If one core touches another, the signal stays clean. The insulation is also PUR or a special PVC blend. It sticks well to the copper. It does not peel off when the cable flexes.
The PUR Sheath (Jacket)
The outside layer is thick PUR. It is not just a cover. It is a shield. It protects against physical damage. If a heavy object rolls over it, the wires inside are safe. If a robot arm drags it, the jacket slides without tearing. It is UV resistant. If you use it outside in the sun, it will not become brittle.
The Fillers and Shielding (Optional)
For the 12-core version, we often use fillers to keep the cable round. A round cable pulls smoother in a drag chain. We can also add shielding. If you have EMI (electromagnetic interference) issues, we can wrap the cores in copper braid or aluminum foil. This stops noise from messing up your data signals.
Where do you use this cable?
You can use this cable anywhere things move. It is a “drag chain control line.” But it is also a power cable. Here are the best places to use it.
Industrial Automation
Robotic arms need this cable. The wrist of a robot twists 360 degrees. Standard cables fail in days. The 855P series lasts for years. Use it for CNC machines, assembly lines, and pick-and-place robots.
Material Handling
Conveyor belts move. Stacker cranes move. The cables hanging from the ceiling get pulled and swayed. This cable handles the constant motion. It is great for automated warehouses and logistics centers.
Heavy Machinery and Mining
Mining equipment vibrates constantly. Excavators and drills move their booms. The cable must resist mud, water, and oil. The PUR sheath is perfect for this dirty environment. It is also cold-resistant for outdoor winter work.
Food and Beverage
This cable is safe for food processing. It is non-toxic. It resists the washdown chemicals used to clean factories. It is also flexible enough for filling machines and packaging robots.
EV Charging and Energy
While usually for control, the 1.5mm² to 2.5mm² range is often used in EV charging stations for the control pilot signal (CP) and proximity pilot (PP). It ensures the car and charger talk to each other safely, even if the cable is moved or stepped on.
Why choose the 855P Series?
There are many cables on the market. Why pick this one?1. It saves money in the long run.Cheap cables break. You pay for the part. You pay for the labor to install it. You pay for the downtime. This cable costs more upfront. But it lasts 5 times longer. You buy it once, not five times.2. It is truly flexible.Many “flexible” cables are only flexible when warm. This PUR cable stays flexible in the cold. It has a small bending radius. You can fit it in tight spaces inside small machines.3. It is oil-proof.In a factory, oil is everywhere. It leaks from hydraulics. It splashes from machines. Standard rubber swells and rots in oil. PUR does not. It stays strong.4. Easy to strip and install.The jacket strips cleanly. You do not need special tools. The wires are easy to solder or crimp. This speeds up your assembly time.5. Compliant with StandardsWe build this to ISO, IEC, and CE standards. It meets the safety rules for Europe and North America. You can use it in your export machines without worry.
Frequently Asked Questions
Q: Is 1.5mm² enough for my motor?A: It depends on the voltage and current. For control signals (24V, 110V) and small sensors, 1.5mm² is plenty. For powering a large 3-phase motor directly, you might need a thicker cable (like 4mm² or 6mm²). But for the control circuit of that motor, 1.5mm² is standard.Q: Can I use this outdoors?A: Yes. The PUR sheath is UV resistant and water-resistant. It handles rain and sun very well. Just make sure the connectors are also waterproof.Q: How long is the delivery time?A: We keep stock of common sizes. For custom colors or very long lengths, we can produce it fast. Usually, we ship within 7 to 15 days.Q: Can you add connectors?A: Yes. We can crimp M12, M8, or Deutsch connectors on the ends. Or we can leave the ends open for you to terminate. Just tell us what you need.
