Tired of Wires That Break, Overheat, or Fail Safety Checks?
You know the struggle. You are in the middle of a wiring project—maybe installing new lights in a house or building a control panel. The wire feels stiff. You try to bend it around a corner, and the copper snaps. Or worse, you worry if the insulation will melt when the current runs high. You need a wire that bends easily without breaking. You need a wire that stays cool. You need a wire that passes inspection every time.We fix these problems. Our single-core flexible wire is not just a piece of metal. It is a complete solution for electricians, DIY makers, and factory builders. We use high-purity copper and soft PVC jackets. This means you get stable power and safe signals. No more headaches. Just reliable connections.
What Makes Our BVR Single-Core Multi-Strand Wire Special?
BVR stands for “Copper-core Polyvinyl Chloride Insulated Flexible Wire.” It is the go-to choice for fixed wiring in homes and buildings. But what does that actually mean for you?First, look at the structure. It is multi-strand. Inside the PVC jacket, you do not find one hard piece of copper. You find dozens of tiny copper strands twisted together. This is why we call it “flexible.” When you pull it through a conduit or a pipe, it moves like a snake. It does not get stuck. It does not kink.Second, the material matters. We use 99.9% high-purity oxygen-free copper. This is not cheap scrap metal. High-purity copper has low resistance. Electricity flows through it easily. This means less heat. Less heat means no fire risk. The wire stays cool even when you run it near its maximum load.Third, the insulation is tough. We wrap the copper in soft PVC. This plastic resists moisture, abrasion, and heat. It is rated for up to 70°C. You can use it in damp basements or hot attics. The colors are clear—red for live, blue for neutral, yellow/green for earth. This makes your wiring neat and easy to read.
The Perfect Wire for Every Scene: From Walls to Circuit Boards
Different jobs need different wires. We cover them all. Here is how you use our products in real life.
Home Decoration and Lighting Circuits
This is the most common use. Electricians love BVR wire for socket circuits and lighting. Why? Because it is easy to route inside walls. If you use a hard single-strand wire (BV), it is difficult to bend in tight junction boxes. Our BVR wire solves this. It fits snugly into terminal blocks but bends easily behind the drywall. It meets national safety standards like GB/T 5023 and has CCC certification. It is safe for 220V household power.
Electronics and DIY Projects
Do you build robots? Or maybe you fix LED strips? You need electronic wire. We supply single-core electronic wire in 0.3mm², 0.5mm², and 0.75mm². These are smaller and finer. They are perfect for Arduino projects, internal wiring of appliances, and connecting circuit boards. The strands are very fine (AWG 22 to AWG 28 range). This makes them perfect for breadboards and PCB jumpers. They do not break when you solder them.
Harsh Environments and Corrosion Resistance
If your wire goes outside or into a marine environment, bare copper rusts. Rust kills conductivity. The solution is tinned copper wire. We coat the copper strands in a thin layer of tin. Tin does not oxidize like copper. It keeps the wire shiny and conductive for years. It is also great for battery cables and welding leads where corrosion is a big risk. Tinned wire is also easier to solder because the tin melts and flows fast.
Technical Specs You Can Trust
We believe in transparency. You need to know exactly what you are buying. Here are the hard numbers for our standard BVR flexible wire series.
| Wire Size (mm²) | Number of Strands | Approx. Outer Diameter (mm) | Max Overload Current (A) | Max Power at 220V (W) |
|---|---|---|---|---|
| 0.75 | 7 or 19 | 2.65 | 10A | 1500W |
| 1.0 | 7 | 2.76 | 13A | 2000W |
| 1.5 | 7 | 3.08 | 19A | 3300W |
| 2.5 | 19 | 3.70 | 26A | 5500W |
| 4.0 | 19 | 4.25 | 34A | 7000W |
| 6.0 | 19 | 4.90 | 44A | 9000W |

Why Choose Our Factory? Quality You Can Feel
You have many choices on Alibaba or eBay. Why pick us?1. Real Copper, Real WeightSome factories cheat by using copper-clad aluminum (CCA). It looks like copper but conducts poorly and breaks easily. We use 99.9% pure copper. You can cut a piece and weigh it. The weight matches the spec. High density means better performance.2. Certified SafetySafety is not a joke. Our wires pass strict tests for flame retardance. If the wire catches fire, the PVC jacket self-extinguishes. It does not spread the flame. This is critical for home decoration wire. We comply with RoHS, REACH, and ISO standards for export.3. No Memory, Easy StripCheap wire has “memory.” You bend it, and it springs back. Our wire stays where you put it. The PVC insulation strips off easily without nicking the copper strands. This saves hours of labor time for installers.4. Custom SolutionsNeed a special color? Need a specific length? Need a wire harness with connectors already attached? We do OEM and ODM. We can print your logo on the insulation. We can make waterproof versions for outdoor LED lights.
Don’t Risk Your Project with Cheap Wire
Imagine this: You finish the wiring. You turn on the power. The lights flicker. The wire gets hot. You have to tear down the wall and start over. That costs time and money.Use the right wire from the start. Our single-core flexible wire is used by thousands of electricians and engineers worldwide. They trust it because it works. It bends. It conducts. It lasts.Whether you are wiring a new house, fixing an arcade machine, or building a custom robot, we have the gauge you need. From tiny 0.3mm² signal wire to heavy-duty 10mm² power cable.Ready to get the best price?Send us your inquiry today. Tell us the size (mm² or AWG), the quantity, and the voltage you need.
