Is your industrial signal cable causing downtime?
You know the frustration. You install a new control system, but the signals keep dropping. Motors start acting weird. Sensors give wrong readings. You check the wires, and they are stiff, hard to pull through conduits, or the shielding is just a cheap foil that tears easily. Worst of all, electromagnetic interference (EMI) from nearby heavy machinery ruins your data.You need a cable that works hard so you don’t have to. You need a cable that is flexible enough for tight spaces, tough enough for factories, and shielded well enough to stop noise. This is not just a wire. It is the nervous system of your machine. If it fails, your whole line stops. Let’s look at the solution that fixes these headaches.
What makes this 34-core shielded cable special?
This is a professional-grade signal control cable built for real-world abuse. We designed it specifically for engineers who need reliability in small spaces. Here is the breakdown of the specs you care about:
- Core Count: 34 cores total.
- Pair Configuration: 17 pairs (17P x 2). This means you have 17 twisted pairs for 17 different signal loops.
- Wire Gauge: 28 AWG. This is the sweet spot for signal wires—thin enough to be flexible, but thick enough to carry data over distance without too much voltage drop.
- Conductor Area: 0.1 square mm (approx 0.12 mm² for 28AWG stranded).
- Conductor Material: Tinned copper. Why tinned? Because bare copper oxidizes (rusts) over time, especially in humid factories. The tin plating keeps the copper shiny and conductive for years. It also makes soldering easier.
- Shielding: Double shield. We use a combination of aluminum foil and a braided copper mesh. The foil blocks high-frequency noise. The braid (90% coverage) blocks low-frequency magnetic fields and provides a ground path.
- Jacket Material: Soft PVC or TPE (Thermoplastic Elastomer). It is oil-resistant, UV-resistant, and flame-retardant. It stays flexible even in cold warehouses.
- Voltage Rating: 300V. Safe for most low-voltage control circuits (24V, 48V, 110V).
- Temperature Range: -20°C to +80°C (or up to 105°C for specific grades).
The structure is simple but effective. Each pair is twisted together. This twisting cancels out interference. Then, the whole bundle is wrapped in shields. Finally, a tough outer jacket holds it all together.
Why choose tinned copper and double shielding?
You might ask, “Why not just use cheaper bare copper?” Here is the truth. In industrial environments, moisture and chemicals are everywhere. If you use bare copper, oxidation builds up on the wire surface. This increases resistance. Your signal gets weak. Eventually, the connection fails. Tinned copper stops this. It is a small extra cost that saves you huge money in maintenance later.The shielding is critical too. In a factory with VFDs (Variable Frequency Drives), servo motors, and welders, the air is full of electromagnetic noise. A simple unshielded cable acts like an antenna. It picks up that noise and sends it to your PLC (Programmable Logic Controller). This causes “ghost” signals or data errors.Our double shield (Foil + Braid) creates a Faraday cage around your signals. It reflects and drains away the noise. The braid also gives the cable mechanical strength. It acts as a “rip cord.” If you need to strip the jacket, you can pull the braid to open it up without nicking the inner wires.
Where should you use this cable?
This cable is a workhorse. We sell a lot of this to different industries. Here are the top places it shines:
Robotics and Automation Arms
Robot arms move constantly. They twist and turn. Standard cables crack after a few months of flexing. This cable is “high flex” rated. It can handle millions of bend cycles. It is perfect for the “drag chain” (cable carrier) on a robotic arm. The soft jacket doesn’t snag on the chain links.
CNC Machines and Servo Motors
CNC machines use precise signals to control position. If noise gets into the encoder cable, the machine crashes. This 17-pair cable is great for connecting servo drives to motors. You can run power in one cable and signals in another, or use the pairs for multi-axis control.
Building Security and CCTV
Need to run video and control data for PTZ (Pan-Tilt-Zoom) cameras? You need multiple pairs. One pair for video, one for power, one for RS-485 control data. This 34-core cable gives you room to grow. You can use 4 pairs for video (using baluns) and have 13 pairs left for sensors, audio, or alarm triggers.
Process Control and Sensors
In chemical plants or food processing, you have hundreds of sensors (temperature, pressure, flow). They all need to talk to a central control room. The twisted pair design ensures that one sensor’s signal doesn’t cross-talk with the neighbor’s signal. The oil-resistant jacket protects against cleaning fluids.
How do we ensure quality?
We don’t just say it’s good. We test it. Every batch goes through strict checks.
- Spark Test: We put high voltage on the wire to make sure there are no tiny holes in the insulation.
- Resistance Test: We measure the ohms per kilometer. It must match the standard (like 381 MΩ/km for 28AWG).
- Flex Test: We bend the cable over a pulley thousands of times to simulate 10 years of use. If it cracks, we reject it.
- Shield Coverage: We check that the braid covers at least 90% of the surface. Gaps let noise in.
- Jacket Strength: We test the tensile strength. The jacket shouldn’t tear when you pull it through a pipe. We also test the elongation. It should stretch a bit before breaking, not snap like glass.
We use high-quality raw materials. The copper is fully annealed (softened) stranded wire. It is not solid core. Solid core breaks if you vibrate it. Stranded wire survives vibration. The insulation is color-coded. We follow standards like MIL-STD or IEC. You get white/blue stripes, orange/white, green/white, etc., so your electricians don’t get confused during installation.
Why buy from us?
You have many choices on Alibaba or from local distributors. But we are a factory, not just a trader. We control the production from the copper rod to the final packaging.
- Customization: Need a different jacket color? Black, yellow, orange, grey? Done. Need a special length? 50 meters, 305 meters, 1000 meters? We can do it. Need “Ripcord” inside the jacket for easy stripping? Add it.
- Certifications: Our cables meet RoHS, ISO 9001, UL, and CE standards. If you need UL approval for your panel, we can provide the file.
- Price: Because we are the source, we cut out the middleman. You get factory-direct pricing. For bulk orders (over 1000 meters), we offer tiered discounts.
- Samples: We send free samples (A4 size or 10-meter coils) so you can test the flexibility and shielding in your lab before placing a big order.
Don’t risk your project with cheap, stiff cable that will fail in six months. Invest in a cable that is soft, shielded, and built to last. This 34-core, 17-pair, 28AWG tinned copper cable is exactly what you need for clean, reliable signal transmission.Ready to get a quote?Send us your inquiry today.
