German Standard 4 Core 0.5 sq mm Shielded Flexible Cable – 115 CY 4G0.5 – Copper Control Wire for CCTV & BMS

Is Your Cable System Letting You Down? Here is the Real Solution.

You have a big problem with your current wiring. The signal keeps dropping. The screen on your CCTV monitor has “snow” or lines running through it. Your intercom buzzes with static noise. Or worse, the stiff cable you bought snaps when you try to bend it around a corner in the conduit. You waste hours fixing connections that should have worked the first time. You worry about fire safety because the insulation smells like burning plastic when it gets warm. You need a wire that works right now and lasts for years. You need a cable that stops electromagnetic interference (EMI) dead in its tracks. You need the German imported cable, 4-core 0.5 sq mm shielded power cable, copper core, flexible type, 115cy4G0.5. This is not just a wire. It is a shield for your signals. It is built for the real world. It solves the noise, the stiffness, and the safety issues all at once.

What Exactly is 115 CY 4G0.5? (The “Brain” of the Cable)

Let us break down the code. “115 CY” is a famous European standard (EN 50525-2-51). It tells you this cable is slim, flexible, and tough. The “4G0.5” part is very specific. It means 4 cores (wires inside) plus a Ground wire. Each core is 0.5 square millimeters in size. This size is the “Goldilocks” of control cables. It is thick enough to carry power and data over long distances (up to 100 meters) without losing voltage. But it is thin enough to stay flexible and fit into small cable glands.This specific model uses a “CY” construction. This means it has a special PVC mix that resists oil and chemicals. If you use this in a factory where there is grease or cleaning fluid on the floor, the jacket will not rot. It is also “screened.” This is the magic word. It has a metal mesh inside that blocks outside noise. If you run this cable next to a heavy power line carrying 220V, your data signal stays clean. No glitches. No errors. Just pure signal.

Technical Specifications: The Numbers You Need

When you buy cable, you need hard facts. Here is exactly what you get with the 4 core 0.5 sq mm shielded cable:

• Conductor Material: Bare copper (Class 5 fine-wire stranding). This is not a solid rod. It is made of many tiny wires twisted together. This makes it super flexible.
• Insulation Material: PVC (Polyvinyl Chloride). It is rated for 300/500 Volts.
• Shielding: Tinned copper braid. The coverage is 85% or more. This catches all the interference.
• Outer Sheath: Grey PVC. It is flame retardant and self-extinguishing.
• Outer Diameter: About 6.5 mm to 7.1 mm. It is very slim. You can fit more of these in a pipe than standard cables.
• Weight: Roughly 71 kg per kilometer. Or about 0.07 kg per meter.
• Temperature Range: You can use it from -5°C to +70°C when moving. If it is stuck in a wall (static), it handles -30°C to +70°C.
• Bending Radius: You can bend it to 6 times the diameter for fixed installations. For flexible use, it is 20 times the diameter. It bends easily!
• Voltage Rating: 300/500 V (Test voltage is 2000 V AC).
• Standards: It meets VDE 0295 Class 5, IEC 60228, and RoHS.

Construction Details: Built Like a Tank, Moves Like a Snake

Why is this flexible power cable better than the cheap stuff from the local market? Look inside.

The Copper Core

The conductor is made of many tiny strands of copper (16 strands of 0.20mm wire per core). This is called “Class 5” flexibility. If you use a solid core wire, it breaks if you vibrate it or bend it often. This copper core wire survives constant movement. It is perfect for robot arms, moving doors, or conveyor belts. The copper is electrolytic. This means it is 99.9% pure. High purity means low resistance. Low resistance means the cable does not get hot.

The Shielding Layer

This is the most important part for signal quality. Between the inner wires and the outer jacket, there is a foil tape and a braid of tinned copper wires. “Tinned” means coated in tin. This stops the copper from rusting. The braid acts like a Faraday cage. It catches electromagnetic noise from motors, fluorescent lights, and radio waves. It drains this noise to the ground wire. Your data stays safe inside.

The Outer Jacket

The grey PVC jacket is tough. It resists abrasion. If you drag it over concrete, it does not scrape off easily. It also has a “non-wicking” filler inside. This means if water gets through a cut in the jacket, it does not travel 10 meters down the cable. It stops right at the cut.

Where to Use This Cable? (Real World Scenarios)

You might ask, “Where can I use this German imported cable?” The answer is: almost everywhere you need low voltage power or signal.

CCTV and Security Systems

This is the #1 use case. You need to power the camera (12V or 24V) and send the video signal back. The 4 core 0.5 sq mm shielded cable does both. The shield stops the video signal from getting “fuzzy” because of nearby power lines. It is also rated for intruder alarm systems.

Building Management Systems (BMS)

Modern buildings are smart. They have sensors for temperature, smoke, and motion. These sensors need a stable power source and a data line. This cable is perfect for connecting the control panel to the sensors. It is small enough to hide in false ceilings.

Industrial Automation

In a factory, you have PLCs (Programmable Logic Controllers) and servo motors. The control signals for these machines are very sensitive. If a big motor starts up, it creates a voltage spike. This cable’s shielding absorbs that spike. It protects your expensive computer equipment.

Audio and Intercom

For background music systems or door entry phones, you need clear sound. The twisted pairs inside reduce “crosstalk” (where one wire talks to another). The result is crisp, clear audio without buzzing.

Why Choose “German Standard” Quality?

You can buy cheaper cable from other places. But you get what you pay for. The German imported cable, 4-core 0.5 sq mm shielded power cable follows strict rules.

1. Consistency: Every meter is the same. The copper thickness does not change halfway through the roll. Cheap cables sometimes get thinner to save money.
2. Fire Safety: The PVC used in German standard cables is “Flame Retardant” (IEC 60332-1-2). If there is a fire, it does not spread the flame. It melts away but stops burning when the heat source is gone.
3. Chemical Resistance: The “CY” compound resists oils and acids. In a garage or a chemical plant, cheap PVC gets sticky and cracks. This cable stays hard and protective.
4. Longevity: Because the copper is pure and the shielding is tight, this cable lasts 15 to 20 years. Cheap cable fails in 2 or 3 years. You save money in the long run because you do not have to re-wire the building.

Installation Tips: Make It Easy for Your Electricians

Your team will love installing this wire. Because it is flexible type, it does not fight back.

• No Heavy Tools Needed: You do not need huge pliers to bend it. You can shape it by hand for gentle curves.
• Pulling Force: The outer sheath is slippery. When you pull it through a long pipe, it slides easily. You can pull longer runs without the wire snapping.
• Stripping: The insulation strips off cleanly. It does not leave a sticky mess on the copper.
• Marking: The cores are color-coded (usually Black with White numbers). It is easy to see which wire is which. You do not need a multimeter just to find the ground wire.

Compliance and Certifications

Do not risk using non-certified cable. If your building fails inspection, you lose money. This cable has the papers you need.

• VDE Approved: This is the German testing standard. It is very hard to get. It proves the cable is safe.
• RoHS Compliant: It has no lead, no mercury, and no cadmium. It is safe for the environment.
• CE Marked: You can sell this cable or use it anywhere in Europe.
• ISO 9001: The factory follows quality management rules.

Frequently Asked Questions (FAQ)

Q: Can I use this cable for 240V mains power?A: No. This cable is rated for 300/500V control and signal use. While it can handle low voltage power (12V-48V), do not use it for 110V or 220V mains household power. It is too thin for high current appliances like heaters.Q: Is the copper real copper or CCA (Copper Clad Aluminum)?A: It is 100% bare copper (or tinned copper for the shield). We do not sell CCA. CCA breaks easily and has high resistance. Our copper core ensures the best conductivity.Q: How do I ground the shield?A: You must connect the drain wire (the bare copper wire inside the braid) to the earth/ground terminal of your equipment. Do this at ONE end only to avoid ground loops.Q: Can you ship this to my country?A: Yes. We ship worldwide. We pack it in coils (50m, 100m) or drums (500m). We use strong packaging to protect the flexible power cable from being crushed during shipping.Q: What is the minimum order quantity?A: It depends on the length. For stock items, we can do 100 meters. For custom production, we usually need 500 meters or more.
