What Makes This Cable Special?
This is not just a piece of wire. It is a high-tech tool for data and signal transmission. The “UNITRONIC LIYCY” name stands for reliability. It comes from strict German engineering (VDE standards). The core feature is the shielding.
The Tinned Copper Mesh Shield
Look at the cross-section. You see three cores inside. Around them is a tight mesh of tinned copper wires. This is the “braid.” It acts like a cage. It catches external noise from motors, welders, or power lines. It keeps that noise away from your precious data signals.
Why “tinned” copper? Tin does not rust. Plain copper turns green and loses connection over time. Tinned copper stays shiny and conductive for years, even in wet or chemical environments. The coverage is usually above 85%. This means almost no noise gets through.
The PVC Jacket and Core Insulation
The outer jacket is PVC (Polyvinyl Chloride). It is tough. It resists oil, acids, and abrasion. If you drag the cable through a machine tray, it won’t scrape off easily. Inside, each of the three cores has its own color-coded PVC insulation. This makes wiring easy. You know exactly which wire is which. Blue, brown, green-yellow—standard colors for easy setup.
Flexibility is Key
Solid wires break if you bend them too much. This cable uses “stranded” conductors. Many tiny copper wires are twisted together to make one core. This makes the cable very flexible. You can route it around tight corners in control cabinets. The minimum bending radius is small. You do not need huge space to install it.
Technical Specifications You Can Trust
We believe in transparency. Here are the hard numbers for the 3*1 sq mm version. These specs match the DIN 47100 and IEC 60332-1-2 standards.
- Conductor: Fine-wire stranded copper (Class 5/6 flexibility). Tinned for corrosion resistance.
- Number of Cores: 3 Cores (Tri-core).
- Nominal Cross-Section: 1.0 mm² (approx 18 AWG).
- Insulation Material: PVC (Polyvinyl Chloride).
- Sheath Material: PVC, Light Grey (RAL 7032) or Black on request.
- Shielding: Tinned Copper Braid (Overall shielding).
- Voltage Rating: Up to 300V for data/control signals (Check local code for power).
- Temperature Range:
- Fixed installation: -40°C to +80°C.
- Moving/Flexing: -5°C to +70°C.
- Capacitance: Core-to-core approx 120 nF/km.
- Inductance: Approx 0.65 mH/km.
- Flame Test: IEC 60332-1-2 (Self-extinguishing).
- Oil Resistance: Yes, suitable for oily environments.
- Outer Diameter: Approx 6.0mm – 6.5mm (varies slightly by braid density).
- Weight: Approx 60-65 kg/km.
These numbers mean the cable works hard. It handles the heat of a factory floor. It survives the cold of an outdoor sensor station.
Where Should You Use This Cable?
Do not use this for high-voltage mains power (like 480V or 600V). This cable is for control and data. It is the nervous system of your machine.
Computer Systems and Server Rooms
In data centers, thousands of cables run together. Without shielding, they create “crosstalk.” Cable A talks to Cable B by accident. The LIYCY shield stops this. It ensures the data goes only where you want it to go.
Industrial Automation (PLC & CNC)
Programmable Logic Controllers (PLCs) are the brains of the factory. They send tiny voltage signals to motors and valves. If a big motor starts nearby, it creates a magnetic spike. A non-shielded cable reads this spike as a “command.” This causes accidents. Use the shielded LIYCY to keep signals clean.
Office Equipment and Medical Scales
Even in offices, EMI exists from Wi-Fi routers and fluorescent lights. Precision scales (like laboratory balances) need stable signals to show the correct weight. The braided shield protects these weak signals.
Audio and Measurement Gear
For professional microphone cables or sensor leads, you need low noise. The tinned copper braid acts as a ground loop breaker. It gives you a clean signal path.
Why Buy From Us?
You can buy from big distributors. But why pay their markup? We are the source.
We Customize for You
Need a different color jacket? Need 500 meters instead of 1000? Need a special connector on the end? We can do it. We have the production lines ready to build your specific order.
We Beat the Price
Because we are a factory, our overhead is lower. We pass the savings to you. You get German-grade quality at a Chinese factory price. This helps you win bids against bigger competitors.
We Ship Fast
We know you need this cable yesterday. We keep stock of popular sizes like 3*1 sq mm. For bulk orders, production is fast. We use reliable forwarders (DHL, FedEx, or Sea Freight) to get it to your door on time.
Quality You Can See
Every batch is tested. We check the continuity of the shield. We check the insulation resistance. We verify the copper is pure. If it leaves our factory, it works. We offer a solid warranty.
Comparison: LIYCY vs. Cheap Alternatives
Let’s be honest. You can find cheaper cable online. But look at what you lose.
| Feature | Our UNITRONIC LIYCY | Cheap Generic Cable |
|---|---|---|
| Shielding | Tinned Copper Braid (90%+ coverage) | Aluminum Foil (Tears easily, poor ground) |
| Copper | 99.9% Pure Tinned Copper | Copper Clad Aluminum (CCA) – Breaks easy |
| Jacket | PVC (Flame retardant, oil resistant) | PE or low-grade PVC (Cracks, burns fast) |
| Flexibility | High (Class 5 stranding) | Low (Stiff, hard to bend) |
| Lifespan | 10+ Years in industry | 1-2 Years before failure |
Cheap cable fails. When a cheap cable fails in a machine, you pay for the part (50),butyoupaymuchmoreforthedowntime(5000/hour). Our cable prevents that. It is an investment in reliability.
Frequently Asked Questions
Is this cable halogen-free?
Standard LIYCY is PVC. PVC contains halogens. If you need Halogen-Free (LSZH) for enclosed public spaces like subways or airports, ask us. We can produce LSZH versions.
Can I use this for Ethernet?
No. This is for serial data, CAN bus, or analog signals. For Ethernet (RJ45), you need twisted pair with specific impedance (100 Ohm) like Cat5e or Cat6. We make those too!
What is the minimum order quantity (MOQ)?
For stock items, we can sell by the meter. For custom production, MOQ is usually 100-500 meters depending on the spec.
How do I strip the jacket without cutting the shield?
Use a proper stripping tool (like a coax stripper). Set the depth just right. If you nick the braid, the shield loses effectiveness. Be careful during installation.
