Is Your Signal Weak? Stop Losing Data and Power Because of Cheap Cables
You have a big problem. You install a security system or a complex machine. Everything looks good. But after a few weeks, the screen flickers. The sensor gives wrong numbers. The alarm goes off for no reason. You check the device, and it is fine. The problem is the wire.Cheap cables act like antennas. They pick up noise from motors, lights, and power lines. This noise ruins your signal. It causes errors. It stops your machines. Also, stiff cables are a nightmare to pull through walls. They break. They waste your time.You need a cable that fights noise. You need a cable that bends easily. You need a cable that lasts. We have the solution. It is the 4 Core 0.5mm² Shielded AVSS Copper Cable. It is built for tough jobs. It protects your data. It saves your money.
What Makes This 4 Core 0.5mm² Shielded Cable So Special?
This is not just a piece of wire. It is a system. Let’s look at the parts that make it work better than the rest.
Pure Copper Cores for Maximum Power
Inside, you find four solid copper strands. Why copper? Because it conducts electricity best. Some sellers use cheap aluminum or mixed metal. That causes voltage drop. Your device at the end gets weak power. Our copper cores ensure full voltage reaches the load. The 0.5mm² size is perfect. It carries enough power for sensors and cameras without being too thick.
The Shield That Stops Noise
This is the most important part. The cable has a shield. It is a braid of tinned copper wires wrapped around the cores. Think of it like a guard. It blocks electromagnetic interference (EMI).If you run this cable near a heavy motor or LED lights, the shield catches the noise. It sends the noise to the ground. Your signal inside stays clean. This is critical for CCTV video. Without a shield, you get snow on the screen. With this shield, the video is crystal clear.
AVSS Flexible PVC Jacket
AVSS stands for a special type of automotive-grade insulation. It is thinner than standard PVC. But it is still strong. This means the whole cable is thinner. It saves space in your cable trays.The jacket is flexible. You can bend it around corners easily. It does not crack when you pull it. It resists oil, water, and chemicals. You can use it outside or in a factory. It handles temperatures from -40°C to 80°C.
Technical Specifications You Can Trust
We believe in honesty. Here are the real numbers for this cable. You can compare them to any other supplier.
| Feature | Specification | What It Means for You |
|---|---|---|
| Number of Cores | 4 Cores | You have 4 separate paths. Use 2 for power, 2 for data. Or 4 for data. |
| Conductor Size | 0.5 mm² (20 AWG) | Perfect balance of strength and flexibility. |
| Conductor Material | Stranded Copper (Tinned) | Tinned copper does not rust. It connects better. |
| Shield Type | Tinned Copper Braid | 90% coverage. Blocks almost all high-frequency noise. |
| Insulation | PVC / AVSS Standard | High dielectric strength. No short circuits. |
| Voltage Rating | 300V / 500V | Safe for 24V, 110V, or 220V systems (check local code). |
| Outer Diameter | Approx 6.5mm – 9.2mm | Fits through small holes. Saves conduit space. |
| Temperature Range | -40°C to +80°C | Works in freezers and hot engine rooms. |

Where Should You Use This Cable? (Real World Scenarios)
This cable is a workhorse. It fits many jobs. Here is how our customers use it every day.
CCTV and Security Systems
This is the #1 use. You need to send video from the camera to the recorder. You also need to send power to the camera. A 4-core cable does both in one go. The shield stops the video from getting “ghost lines” or static. It works for analog cameras and HD-TVI systems.
Industrial Automation and PLC
Factories are noisy places. Motors create huge magnetic fields. If you use a normal wire, the sensor signal gets corrupted. The machine stops. The production line halts. You lose money.With this shielded cable, the signal stays true. The PLC (Programmable Logic Controller) gets the right data. The machines keep running. It is perfect for connecting proximity switches, limit switches, and solenoid valves.
Building Management and Access Control
Do you install electric locks, card readers, and intercoms? You need reliable data and power. This cable handles the low-voltage signals for the door system. It also handles the audio for the intercom. The twisted pairs inside reduce crosstalk. The audio is clear. The door opens on time.
Audio and Broadcast
For balanced audio lines, you need twisted pairs. This cable has them. It prevents hum and buzz from lighting dimmers. It is great for installing background music systems in offices or shops.
Automotive and Special Vehicles
Since this uses AVSS specs, it is great for cars, boats, and RVs. It handles the vibration of an engine. It resists the oil and grease found in garages. It is thin enough to fit through car door hinges without breaking.
Why Choose Our 4 Core Shielded Wire Over Others?
You will find many cables online. Some are cheaper. But cheap costs you more later. Here is why we are different.
We Don’t Cheat on the Copper
Some factories make the copper strands too thin. They make the insulation too thick. The cable looks big, but the metal inside is weak. Our cable meets IEC 60228 standards. The copper is thick enough to carry the current. We use high-grade stranded copper. It is flexible and strong.
Real Shielding, Not Just Foil
Cheap cables use aluminum foil. It tears easily. It breaks when you bend the cable. Once it breaks, the shield is useless. We use a braided copper mesh. You can pull it, bend it, and twist it. The shield stays intact. It protects the signal for years.
Better Markings for Easy Installation
Electricians hate guessing which wire is which. Our cable has clear printing on the jacket. “Core 1,” “Core 2,” “Shield.” The cores are color-coded (Black, White, Red, etc.). This cuts your installation time in half. You make fewer mistakes.
Oil and Fire Resistant
Standard PVC gets soft in oil. It melts. Our PVC compound is special. It resists oil. It also resists flame. If there is a small spark, the cable does not spread the fire. This is vital for safety in public buildings.
Frequently Asked Questions About This Cable
Q: Can I use this for PoE (Power over Ethernet)?A: No. This is not a Cat5 or Cat6 cable. It is for low-speed data and power control. Do not use it for high-speed internet.Q: How do I ground the shield?A: You must ground the drain wire (the green/yellow one) at one end only. Usually, you ground it at the control panel side. If you ground both ends, you can create a ground loop. This causes buzzing.Q: Is this cable waterproof?A: The PVC jacket is water-resistant. It is fine for rain and damp conditions. But if you put it directly in water for a long time, use a conduit or a waterproof gland.Q: What is the difference between 4-core and 3-core?A: A 3-core cable usually has Power +, Power -, and Signal. A 4-core gives you an extra wire. You can use it for a second signal, a second power line, or an audio channel. It gives you more options for the future.Q: Can I bury this cable underground?A: Yes, but you must put it in a pipe or conduit. Direct burial requires a special armor cable. This cable is not armored against rocks.
