Is Your Cable System Letting You Down?
You know the feeling. You install a new cable run in your factory or control panel. Everything looks good. But two weeks later, the machines start acting weird. Sensors give wrong readings. The touch screen freezes. Or worse, the cable cracks inside the drag chain, and you have to shut down the whole line to fix it.This costs you money. Every hour of downtime is lost profit. Cheap cables break. Stiff cables are a nightmare to pull through tight pipes. Unshielded cables pick up noise from motors, ruining your data signals.You need a cable that works hard, bends easily, and stays quiet. You need a cable built for the real world, not just a lab. We are a cable factory, and we see these problems every day. That is why we bring you the LiYY 16×0.25mm² data transmission cable. It is the “gold standard” for low-voltage control and signal systems. It solves the pain of installation and the fear of failure.
What Exactly is LiYY 16×0.25mm² Cable?
Let’s break it down simply. This is not a power cable. It does not carry high voltage. It carries information. It is the “nervous system” of your machine.LiYY is a specific code. It tells engineers exactly what is inside.
- Li: It stands for low-frequency data or control signal.
- Y: The first Y means PVC insulation around the copper wire.
- Y: The second Y means PVC outer sheath (the black or grey skin).
The 16×0.25mm² part is the size.
- 16 Cores: You get 16 separate wires inside one jacket. This means one cable can do 16 jobs. It saves space and money.
- 0.25mm²: This is the thickness of the copper wire. It is the “sweet spot.” It is thick enough to carry signals over long distances (up to 100 meters) but thin enough to stay flexible.
This specific type is often called a multiconductor control cable or a 16-core signal line. In the US and Europe, it is used everywhere—from conveyor belts to medical scales.
Built Like a Tank, But Flexible Like a Snake
You might think a strong cable must be stiff. Not this one. We use a special manufacturing process called “fine-wire stranding.”
Ultra-Fine Copper Stranding
Inside the grey PVC jacket, you won’t find one solid wire. Solid wires break if you bend them too much. Instead, you find hundreds of tiny copper threads twisted together. This is Class 5 flexible copper.This design makes the cable ultra-soft. You can bend it around tight corners without kinking it. If you use it in a moving part (like a robot arm or a sliding door), it handles the stress much better than solid wire. It resists metal fatigue. This means it lasts longer in drag chains (cable carriers).
Tough PVC Jacket
The outer skin is made of high-quality PVC. It is not just plastic. It is engineered to resist oil, acids, and abrasion. If you work in a factory with coolant leaks or dust, this jacket protects the delicate signals inside.It is also flame-retardant. If there is a short circuit spark, the cable does not catch fire easily. It meets the IEC 60332-1-2 standard. This is a must-have for building safety codes in Europe and North America.
Technical Specs You Can Trust
We don’t hide the numbers. Here is exactly what you get with our standard LiYY 16×0.25mm²:
| Feature | Specification | What It Means for You |
|---|---|---|
| Conductor | Bare Copper, Class 5 | Maximum flexibility, high conductivity. |
| Cross Section | 0.25 mm² | Perfect balance of strength and flexibility. |
| Number of Cores | 16 | Handles complex control systems with one cable. |
| Insulation | PVC | Standard, reliable, and heat resistant. |
| Sheath Color | Grey (RAL 7032) | Professional look, easy to identify in panels. |
| Outer Diameter | Approx. 7.7 mm | Fits into standard cable glands and conduits. |
| Weight | Approx. 80 kg/km | Light enough for overhead runs. |
| Voltage Rating | 300V / 500V | Safe for low-voltage control circuits (24V, 110V). |
| Temperature (Fixed) | -40°C to +80°C | Works in freezing warehouses or hot engine rooms. |
| Temperature (Moving) | -5°C to +70°C | Safe for moving parts and drag chains. |
| Bending Radius | 4x Diameter (Fixed) / 10x Diameter (Moving) | You can bend it tight without damaging it. |
Note on Shielding:The standard LiYY is unshielded. This is fine for most indoor environments. But, if you are near big motors, VFDs (Variable Frequency Drives), or welders, you need the LiYCY version. LiYCY has a copper braid shield that blocks electromagnetic interference (EMI). We can supply both. Just tell us your environment.
Where Should You Use This Cable?
This cable is a workhorse. You will find it in thousands of applications. Here are the top scenarios where our clients use the 16 core control cable:
Industrial Automation & PLCs
This is the #1 use case. Connecting Programmable Logic Controllers (PLCs) to sensors, actuators, and HMI panels. The 16 cores allow you to run power, ground, and multiple I/O signals in one go. It keeps your control cabinet clean and organized.
Robotics and CNC Machines
Robots move. CNC axes slide. Cables inside the drag chain face millions of bends. The ultra-soft LiYY construction handles this motion perfectly. It does not snag or break. It keeps the robot arm moving smoothly.
Building Management Systems (BMS)
Used for fire alarms, HVAC controls, and security cameras. The flame-retardant PVC jacket makes it safe to run through walls and ceilings. It is color-coded (DIN 47100 standard), so electricians can wire it fast without checking a manual every time.
Medical and Laboratory Equipment
Precision scales, MRI machine components, and lab analyzers need clean signals. The stable copper ensures accurate readings. The cable is also easy to clean and resists chemicals used in labs.
Audio and Broadcast (Low Voltage)
While not a professional audio cable, it works great for background music systems in offices or malls. It handles the low-voltage speaker lines and control signals for volume knobs and zone selectors.
Why Buy From Us? We Are the Factory.
You can buy LiYY cable from big brands like Lapp Kabel or Helukabel. They are good. But they are expensive. You are paying for their marketing and their warehouse in Germany.We are a Chinese cable factory. We make the same quality product. We use the same copper, the same PVC, and the same German standards (VDE 0812).Here is the difference:
- Price: We cut out the middleman. You get a factory-direct price. It is usually 30-50% cheaper than European imports.
- Customization: Need a black jacket? Need special printing on the cable? Need a different core count? We can change the production line fast. Big brands take weeks; we take days.
- Stock: We keep popular sizes like 16×0.25mm² in stock. You don’t wait 4 weeks for shipping from Europe.
- Certificates: We provide CE, RoHS, and ISO certificates. Your project will pass inspection.
We understand the export market. We know how to pack the cable so it doesn’t get crushed in a container. We know how to label the drums so customs clears it fast.
Installation Tips for Long Life
Even the best cable fails if installed wrong. Here are 3 quick tips to make your LiYY cable last 10 years:
- Don’t Pull Too Hard: These cables have strength members, but they are not steel ropes. Use a pulling grip on the conductor, not the sheath. Keep tension low.
- Respect the Bend Radius: The rule is simple. Don’t bend it sharper than 4 times its diameter when fixed, or 10 times when moving. If you kink it, the impedance changes, and signals get distorted.
- Strip Carefully: Use the right wire stripper. If you nick the copper strands, they can oxidize or break off later. A “nick” is a future failure point.
