Tired of cables that break, overheat, or fail to flex? We have the solid copper solution you need.
You know the struggle. You buy a motor power cord or control wire, and it feels stiff. It cracks after a few bends. The voltage drops because the copper is not pure enough. Or worse, the insulation melts when the motor gets hot. This causes downtime. It causes safety risks. And it costs you money in repairs and lost time.We fix this problem. Our 4-core 1.5 square millimeter cable is not just another wire. It is a heavy-duty, flexible power cord built for real work. We use 100% pure copper. We use high-quality PVC insulation. This wire handles 300/500V easily. It stays flexible in cold weather. It resists oil and abrasion. Whether you need a VCTF flexible wire for a portable machine or an RVV control cable for a fixed line, this product works. It is the bridge between your power source and your machine. It keeps the energy flowing smoothly. No interruptions. No overheating. Just reliable power.
What makes this 4×1.5mm² Pure Copper Cable special?
This is not cheap aluminum wire coated in copper. This is real, solid copper. Look at the conductor structure. We use fine stranded copper wires. This makes the cable very flexible. You can bend it around corners without damaging the core. The “R” in RVV stands for “flexible.” The “V” stands for PVC insulation. The second “V” stands for PVC sheath.The sheath is tough. It protects the inner cores from physical damage. It also resists water and oil. Inside, you have 4 cores. Each core is 1.5mm². This size is perfect for many motors. It can handle up to 39 amps in short bursts for 48V systems. It is also great for signal control. The colors are standard. You get yellow-green for ground. Blue, brown, and black for the phases. This makes wiring easy for your electricians. They do not need to guess which wire is which.The outer diameter is about 9.2mm to 9.6mm. It is round and smooth. It pulls easily through conduits. It does not get stuck. If you use this as a motor power cord, it handles the vibration well. If you use it as a control wire, it shields against electromagnetic interference (EMI) better than unshielded cables, especially if you choose the shielded RVVP version.

Where to use this cable? Real-world scenarios
You might ask, “Is this the right wire for my project?” Here are the top uses for this specific cable.
Motor Power Cords (VFD & Servo Motors)
This is a top use case. If you have a 400W or 1500W motor running at 48V DC or low voltage AC, this wire works great. Look at the motor parameter tables in many industrial manuals. They often show 4 cores for power. You connect U, V, W phases and PE (Ground). Our cable handles the high current (up to 39A for short duty cycles). It also handles the vibration from the motor. The flexible PVC jacket moves with the motor. It does not stiffen up and crack.
Control & Automation Wiring
In a control panel, you need reliable connections. This 4×1.5mm cable is perfect for connecting PLCs to sensors, relays, and actuators. The 1.5mm² cross-section is thick enough to carry control signals over long distances without voltage drop. It is also strong enough to be pulled through cable chains (drag chains) in robotic arms. If you need more protection, ask for the shielded version (RVVP) with a copper braid. This stops noise from other machines messing up your signals.
Logistics and AGV Systems
Modern warehouses use Automated Guided Vehicles (AGVs). These robots move all day. Their power cables get twisted and bent thousands of times. Standard wire breaks in weeks. Our high-flex cable lasts for months or years. It fits the steering motors and drive motors of logistics units. The outer sheath resists the scuffing from concrete floors. It handles the oil and grease found in maintenance areas.
Household & Industrial Appliances
You can use this wire inside washing machines, conveyor belts, or kitchen equipment. It is safe for damp rooms. It is also safe for outdoor use if you protect it from direct UV sunlight (or use a UV-resistant black sheath). The flame-retardant property means it will not spread fire if a short circuit happens inside a machine.
Packaging, Shipping, and Quality Control
We know you need the cable to arrive in perfect condition. We do not just throw it in a box.
Packaging Options
- Coils: 100 meters or 200 meters per coil. Wrapped in shrink film to keep moisture out.
- Drums: Wooden drums or plywood reels for long runs (500m, 1000m). This prevents kinks during shipping.
- Cartons: For shorter lengths or sample orders.
Shipping Logistics
We ship worldwide. For sea freight, we use pallets to secure the drums. For air freight, we use smaller, lightweight packaging. The cable is not heavy, but the volume matters. A 100m coil is about 10-12kg. A wooden drum can weigh up to 300kg. We handle all export documentation, including CE certificates and Certificates of Origin.
Quality Tests
Before we ship, we test every batch.
- Conductor Check: We measure the copper diameter and strand count. It must be 48/0.20mm.
- Resistance Test: We check that the resistance is under 13.5 Ohms/km.
- Voltage Test: We apply 2000V for 5 minutes. No breakdown allowed.
- Insulation Resistance: We test at 20°C. It must be over 200 MΩ·km.
- Physical Test: We bend the cable around a mandrel 15 times its diameter. The insulation must not crack.
Why choose us as your supplier?
You have many choices on Alibaba or Amazon. Why pick us? Because we are a factory, not just a trader. We control the raw material. We buy the copper cathode directly. We make our own PVC compound. This keeps the price fair. It also keeps the quality high.We have been making cable since the early 2000s. We know the standards. We know BS6500. We know VDE. We know UL. If you need a custom color, we can do it. If you need a special print on the sheath (like your company logo every meter), we can do it. If you need a 4-core cable with an extra pair of twisted pairs for encoder data (4+2 cores), we can make that too.Our customers come back because we do not lie about the specs. When we say 1.5mm² pure copper, it is 1.5mm² pure copper. Not 1.3mm². Not copper-clad aluminum. This honesty saves you money on warranty claims and rework.
