Premium 6-Core Shielded Twisted Pair Cable – 0.35 sq mm Tinned Copper – High Tensile Strength & Flexible for Industrial Automation, Robotics & Medical Devices

Tired of cables that break, tangle, or ruin your signals?

You know the feeling. You install a new cable run for your medical sensors or robotic arm. Everything works fine for a week. Then, the signals start acting weird. Your data gets errors. You check the connection, and the cable is stiff, cracked, or the shielding is falling apart. Worst of all, the wires inside snap because they aren’t strong enough to handle the movement.This happens with cheap cables. They use low-quality copper that corrodes. They skip the real shielding. And they use plastic that turns brittle after a month. You end up spending more money on replacements and repairs than you saved on the initial purchase.You need a cable that moves like a snake but protects like a tank. You need a cable that stops electromagnetic noise from killing your data. And you need it to last for years, even in tight spaces or moving machinery.That is exactly why we built this 6-core shielded twisted pair cable. It is designed for the tough jobs where other cables fail.

What makes this cable different?

This is not just a standard wire. It is a high-performance tool for your machinery. Let’s look at the core features that solve your biggest headaches.

0.35 sq mm Tinned Copper Conductor

We use tinned copper, not bare copper. Why? Because bare copper rusts when it touches air or moisture. Rust equals bad signals. The tin coating protects the copper for a long time. The 0.35 sq mm size (approx. 22-24 AWG) is the “Goldilocks” size. It is thick enough to carry power and data reliably, but thin enough to stay flexible.

3 Pairs of Twisted Wires

Inside the jacket, you have 6 wires total. These are arranged in 3 pairs. Each pair is twisted together. This twisting is not for looks. It cancels out noise. If you run this cable next to a motor or a power line, the twists keep the interference out of your signal.

Dual Shielding Protection

We offer two layers of defense. First, each pair has its own shield (foil or braid). Second, there is an overall shield around the whole bundle. This “double shield” stops outside noise from getting in. It also stops your signal from leaking out. This is critical for medical equipment like SpO2 sensors or high-speed data lines.

High Flexibility & Oil Resistance

The outer jacket is made of special PVC or XLPE mix. It resists oil, which is common in factories. It also resists abrasion. You can bend this cable around tight corners without kinking it. The minimum bend radius is very low, so it fits in crowded cable trays.

High Tensile Strength

This is the breakage stopper. The conductor strands are made of many tiny wires twisted together, not one solid wire. Solid wires snap when you pull them. Stranded wires stretch. This cable can handle a pulling tension of up to 50 lbs (approx. 23 kg) during installation. It won’t snap when you drag it through a conduit.

Where can you use this cable?

This cable is a workhorse. It fits many industries because it solves the “noise” and “movement” problems. Here are the top places we see it used.

Medical & Healthcare

Hospitals need perfect signals. This cable is used for SpO2 extension cables, electrode sensors, and patient monitoring systems. The shielding ensures the heart monitor reads correctly, even with other machines running nearby. The biocompatibility options make it safe for skin contact.

Industrial Robotics & Automation

Robot arms move constantly. Standard cables fatigue and break at the joint. This cable is highly flexible (high flex). It can handle millions of bending cycles. It is perfect for servo motors, encoder feedback, and control panels in automated assembly lines.

Security & Surveillance

CCTV systems often use multi-core cables for video, audio, and power. The 6-core setup is ideal for PTZ cameras that need power, video out, and data control all in one line. The shielding prevents “ghosting” in the video signal caused by nearby power lines.

Audio & Data Networks

While Cat6 is common, sometimes you need a custom cable for specific industrial networks. This cable works for RS485, Profibus, or CAN bus systems in noisy factory environments. The 100 Ohm impedance (optional) matches standard data protocols perfectly.

Technical Specifications (The Nitty Gritty)

Here is the hard data. You can compare this to your current supplier. You will see the quality difference.

Electrical Performance

• DC Resistance: Approx. 16 – 25 Ohms/km (depending on exact AWG). Lower is better for power.
• Attenuation: Very low loss at high frequencies. For data up to 100MHz or more.
• Impedance: 100 Ohms ±15 (Standard for data). We can tune this for specific needs.
• Shielding Effectiveness: > 85% coverage. Blocks RFI/EMI.

Why choose our factory?

You have many choices on Alibaba or Made-in-China. But most traders just repack generic wire. We are a factory that controls the process.We control the raw material. We buy high-grade copper cathode, not scrap. We test the tin plating thickness. If the tin is too thin, it rusts. We make sure it is thick enough.We have the right machines. We use German-made stranding machines. This ensures the wires are twisted evenly. If the twist pitch is wrong, the cable creates its own noise. Our machines keep the twist consistent over kilometers of wire.We test every batch. We don’t just guess. We use capacitance bridges and TDR (Time Domain Reflectometer) testers. We check for shorts, opens, and impedance mismatches before we ship.Customization is easy. Need a special outer diameter to fit a connector? Need a different color for organization? Need a special oil-resistant jacket? We can make it. We don’t just sell from a catalog. We build to your print.

Frequently Asked Questions

Q: Is this cable suitable for outdoor use?A: Yes. We can add a UV-resistant black PE jacket. It handles sunlight and rain well. For direct burial, we recommend the steel wire armored (SWA) version.Q: Can I use this for PoE (Power over Ethernet)?A: Absolutely. The 0.35 sq mm conductors can handle the current for PoE cameras and devices. Just make sure your total power draw is within the ampacity of the wire (usually 1-2 Amps per conductor).Q: How does the “drain wire” work?A: The drain wire is a bare copper wire inside the shield. You connect it to the ground on your device. This makes installation easier because you don’t have to strip the foil shield to ground it.Q: What is the minimum order quantity (MOQ)?A: For standard items, we keep stock. For custom colors or printing, the MOQ is usually 1000 meters. We are flexible for trial orders.Q: Do you provide samples?A: Yes. We can send you a 1-meter or 5-meter sample for testing. You pay for shipping, but the wire is free if you place an order later.
