Introduction to BVV wires

BVV wire is derived from BV wire, which is a wire with an extra layer of sheath than BV wire, the letter B represents the cloth wire, and the letter V represents the polyvinyl chloride in the plastic.

The full name of BVV wire is copper core PVC insulated PVC sheathed round sheathed wire, also known as light PVC sheathed cable, commonly known as hard sheathed wire. Copper core (hard) cloth wire, single core is round, double core is flat. It is often used for exposed wires.

BVV wire is also known as "light PVC sheathed cable" and is usually used for surface-mounted wires. The reason why it is called "BVV wire" is because the letter B stands for "cloth wire" and the letter V stands for "polyvinyl chloride".

merit

In the manufacturing process of BVV wire, the materials are mainly copper wire and insulating materials such as PVC or polyethylene. They have the advantages of high mechanical strength, excellent insulation properties and stable electrical properties. The overall soft sheath structure of the BVV wire can protect the internal copper core wire from external force extrusion and cause the core to break. BVV line is widely used because of its relatively low cost, easy laying, and low failure rate.
