Is your factory cable breaking down? Stop losing money on stiff, cheap wires that crack.
You know the problem. You have expensive machines sitting idle because a power cord failed. Or maybe the cable is so stiff that you cannot route it through the machine arm. It gets hot, the insulation melts, and suddenly you have a short circuit. This is not just annoying. It costs you time and money. You need a wire that moves when the machine moves. You need a wire that resists oil, chemicals, and rough handling. You need a cable that works as hard as your team does. We have the solution. Our 5-core 0.75mm² flexible cable is built for the real world. It is not just a wire. It is the lifeline of your automation system.
What exactly is this 5-core 0.75mm² RVV Cable?
Let’s break it down simply. This is a multi-core cable. It has five separate copper wires inside one outer jacket. Each copper wire has a cross-section of 0.75 square millimeters. This size is the “sweet spot” for control signals and power in small to medium machines. It is flexible but strong. The “RVV” code tells you what it is made of. The “R” stands for soft wire. The first “V” stands for PVC insulation on the inner wires. The second “V” stands for PVC sheath on the outside. This double layer of PVC protects the copper from the outside world. It keeps moisture, oil, and dust away from the electricity. This cable is often called “machine tool power cord” or “motor lead wire” in the industry. It is also used as a “5G 0.75 flexible wire” for signal transmission, though it is not for 5G internet—it is just a name for high-flex data cables in some catalogs.
Technical Specs That Matter to You
You need hard numbers to make a decision. Here is the data you need to know. This cable is designed to handle tough conditions.
Electrical Power and Voltage
- Rated Voltage: 300 Volts to 500 Volts. Some UL versions handle up to 600 Volts.
- Test Voltage: 2000 Volts (for 5 minutes) to ensure no leaks.
- Conductor: Bare copper strands. We use Class 5 fine stranding. This means the wire is made of many tiny wires twisted together. This makes it super flexible.
- Insulation: PVC (Polyvinyl Chloride). It is flame retardant.
- Sheath: PVC. It is tough against physical impact.
Physical Size and Structure
- Core Count: 5 Cores.
- Cross Section: 0.75 mm² (approx 18-19 AWG).
- Outer Diameter: About 7.2mm to 8.7mm depending on the brand standard (like Helukabel or MISUMI).
- Bending Radius: Fixed installation is 4 times the diameter. Moving installation is 7.5 to 15 times the diameter. Do not bend it too sharp or you will damage it.
- Weight: Lightweight but durable.
Performance Limits
- Temperature: Works from -30°C to +70°C. Special versions go to +90°C or +200°C (if silicone), but standard PVC is 70°C.
- Oil Resistance: Yes, standard PVC resists oil. For heavy oil, we recommend special NBR or oil-resistant PVC blends.
- Flame Test: Passes IEC 60332-1. It does not spread fire easily.
Where Can You Use This Cable?
This wire is everywhere in modern industry. It is a “general purpose” workhorse. Here are the top places you will see it:
Machine Tools and CNC
This is the #1 use. It connects the control panel to the motor. It carries power and signals to the cutting tool. If your CNC machine moves, this cable moves with it. It resists the coolant oils found in machine shops.
Motor Leads
Connect electric motors to the drive. The 0.75mm² size is perfect for small to medium servo motors and stepper motors. It handles the current without getting too hot.
Automation and Robotics
You see this in robot arms. The cable goes inside the “energy chain” (drag chain). It needs to flex millions of times without breaking. Our cable uses fine stranding (Class 5) to survive this constant movement.
Building and Security
Use it for fire alarms, intercom systems, and CCTV cameras. The black or grey sheath looks clean. The 5 cores allow you to power the camera and send video signals in one cable.
Specialized Uses
- Heating Systems: Some versions (like 3185Y) are used for thermostat wiring in floor heating.
- Solar and PV: While bigger cables are used for main lines, 0.75mm² is used for sensor wiring in solar inverters.
- Audio/Video: Sometimes used for speaker wiring or low-voltage lighting.
Why Choose Our “Imported Quality” Cable?
You might ask, “Why buy from you?” The market is full of cheap cables. Here is the difference.
Real Copper, Not Junk
Cheap cables use CCA (Copper Clad Aluminum). It breaks easily and heats up. We use 99.9% pure electrolytic copper. It conducts better and lasts longer.
Strict Standards
Our cable meets global standards.
- China: CCC certification (GB/T 3956).
- Europe: CE, VDE, RoHS, and REACH.
- North America: UL and CSA (like SJT or SVT styles).
- UK: BS 6360.
The “Japan Quality” Standard
Even if we ship from China, we follow the strict quality control seen in Japanese exports (like Kuramo or Nachi cables). We check the insulation thickness. We test the voltage. We ensure the sheath is thick enough. You get reliability without the high “brand name” markup.
Packaging and Length
Most cables come in 100-meter rolls. This is the industry standard. It is enough for most projects. We can also cut to length if you need specific meters (like 50m). The cable is marked on the surface every meter or every foot so you can measure easily.
Frequently Asked Questions About This Cable
Is this cable shielded?
Standard RVV is not shielded. If you need shielding for noise (like in audio or sensitive sensors), look for “CY” cables or “Screened” versions which have a copper braid or foil shield.
Can I use this outdoors?
Standard PVC RVV is not for direct sunlight (UV). It will crack after a few months. For outdoors, you need “SJTW” or rubber cables (like H05RR-F) which are UV and weather resistant.
What colors are the cores?
For 5 cores, the standard is usually: Blue, Brown, Black, Grey, and Green/Yellow (for ground). We can do custom colors if you order in bulk.
How many amps can it handle?
For 0.75mm² copper in open air, it can handle about 10 to 13 Amps safely. Always check your local electrical code.
