Is Your Cable Failing When You Need It Most?
You know the feeling. You install a cable in a machine or a building wall. A few months later, it cracks. The signals get messy. The machine stops. You lose money because of downtime. Cheap cables break easily. Rigid cables are a nightmare to install in tight spaces. You need a wire that bends without breaking, carries power and signals clearly, and lasts for years. You need a cable that meets strict safety standards like CE, VDE, and ROHS. If you are an engineer, a facility manager, or a machine builder, you want one thing: reliability. You don’t want to fix wires every week. You want to install it once and forget about it. This 4-core 0.75mm² flexible copper cable is the answer to these headaches. It is built for movement, heat, and heavy use.
What Makes This 4-Core 0.75mm² Cable Special?
This is not just a standard wire. It is a flexible powerhouse. We use high-purity copper for the conductor. Why copper? Because it conducts electricity better than aluminum. Less resistance means less heat. Your equipment runs cooler and safer. The “4×0.75mm²” size is the sweet spot. It is thick enough to carry power for motors and lights. It is also thin enough to carry data signals without interference.The “4-core” design means you have four separate wires inside one jacket. You can use two for power (like 24V or 110V) and two for control signals (like start/stop buttons or sensor data). This saves space. You only need to pull one cable instead of two. The jacket is made of PVC (Polyvinyl Chloride). PVC is tough. It resists oil, water, and abrasion. It is also flame retardant. If there is a short circuit, the PVC jacket helps stop the fire from spreading. This is critical for building safety and machine safety.
Technical Specifications You Can Trust
We believe in transparency. Here are the hard numbers for this 4×0.75mm² cable:
Electrical Properties
- Conductor Material: Annealed plain copper (solid or stranded). We use stranded copper for flexibility.
- Conductor Cross-section: 0.75 mm² per core.
- Number of Cores: 4 cores (usually Black, Blue, Brown/Red, Green/Yellow).
- Nominal Voltage: 300/500V (Uo/U). Some versions are rated 450/750V.
- Insulation Material: PVC (Polyvinyl Chloride).
- Sheath Material: PVC.
- Temperature Range: -20°C to +70°C (fixed installation). For flexible use, it handles up to 70°C.
- Bending Radius: For fixed cables, it is 4x the outer diameter. For flexible cables, it is 6x to 10x the outer diameter.
Physical Properties
- Outer Diameter: Approx. 7.0mm to 8.5mm (depending on insulation thickness).
- Weight: About 80-100 kg per kilometer.
- Color: Black is standard. We can do White, Grey, or Blue for signal cores.
- Shielding: Optional. We offer unshielded (UTP) and shielded (FTP/Braided) versions. Shielding stops noise from motors interfering with your data.
- Flame Test: Passes IEC 60332-1 flame retardant test.
Certifications
- International: CE, ROHS, ISO9001, VDE, IEC 60227.
- China Standard: GB/T 5023 (equivalent to IEC 60227).
- Fire Safety: Meets GB/T 19666-2005 for flame-resistant cables.
Where Can You Use This Cable?
This cable is a workhorse. You will find it in three main areas:
1. Industrial Machinery & Robotics
This is where the cable shines. Use it for CNC machines, robotic arms, and conveyor belts. The cable needs to move. If you use a hard wire in a robot arm, it will snap after a million moves. Our flexible cable handles constant motion. It is perfect for servo motors and encoder feedback. It resists coolant and oil found in factories.
2. Building Automation & Control
Use this for lighting control, fire alarms, and HVAC systems. The 0.75mm² size is great for LED lighting strips and sensor networks. Because it is PVC sheathed, it is safe to run inside walls or in cable trays. It meets the low-smoke requirements for public buildings like hospitals and schools.
3. Household & Commercial Equipment
You can use this for washing machines, refrigerators, and office equipment. It connects the control board to the motor. It is safe for DIY projects too. If you are wiring a workshop, this is the cable you need for your power outlets and tool chargers.
Why Choose This Over HELUKABEL or LAPP?
You might know big brands like HELUKABEL or LAPP. They make great cables. But they are expensive. You pay a lot for their brand name and logistics in Europe or the US. We are a direct manufacturer. We make the same quality cable but at a better price.Our factory uses the same machinery and testing standards. We have ISO9001 certification. We test every batch for spark integrity and resistance. Our copper is 99.9% pure, just like the big brands. We can also customize. Need a special color? Need a special length? Need a tag on every meter? We can do it. Big brands often have minimum order quantities (MOQ) of 10,000 meters. We are flexible with smaller runs and bulk containers. You get the German-level quality without the German price tag.
How We Ensure Quality
Quality is not an accident. It is a process.
- Raw Material Check: We test the copper rods before they enter the drawing machine.
- Online Monitoring: Lasers measure the diameter of the wire in real-time. If it is 0.74mm, the machine stops. It must be 0.75mm.
- Spark Testing: Every meter passes a high-voltage spark test to find tiny holes in the insulation.
- Aging Test: We bake samples in an oven to simulate 10 years of use. The PVC must not crack.
- Flexing Test: We bend the cable 10,000 times in a lab to ensure the copper strands don’t break.
Packaging and Shipping
We know logistics matter.
- Packaging: Coils are wrapped in plastic film to stop moisture. Outer packaging is woven bags or wooden drums for sea shipping.
- Length: Standard coils are 100m or 500m. We can cut to length.
- Container Load: A 20ft container holds about 5000kg to 8000kg of cable.
- Lead Time: 15 days for standard items. 25 days for custom colors.
Frequently Asked Questions
Q: Is this cable suitable for outdoor use?A: Yes, but it needs UV protection. Standard black PVC resists sunlight for a while. For permanent outdoor use, we recommend adding a black PE (Polyethylene) outer sheath or putting it in a conduit.Q: Can I use this for 240V mains power?A: Yes. The voltage rating is 300/500V. It is safe for 110V, 220V, and 240V applications as long as the current (amps) does not exceed the limit for 0.75mm² (approx. 6-10 Amps depending on installation).Q: What is the difference between RVV and LIYCY?A: RVV is the Chinese standard for flexible PVC sheathed cable. LIYCY is the German/European standard for flexible control cables. Our cable meets both standards. LIYCY often has better shielding and tighter color codes.Q: Do you provide samples?A: Yes. We can send you a 50-meter sample coil for testing. Contact us for the sample fee and shipping cost.
