BV wire, also known as copper-core polyvinyl chloride insulated wire in Chinese, or simply copper-plastic wire, is a single-core, rigid conductor wire. BVR wire, on the other hand, is known as copper-core polyvinyl chloride insulated flexible wire in Chinese, which refers to a flexible copper-plastic wire. Both are insulated wires. In terms of core structure, BV wire consists of a single core and an insulation layer, while BVR wire consists of multiple conductors and insulation layers. BVR wire is relatively flexible and can be used in flexible environments. BV wire is relatively rigid and can be used in conduits, generally suitable for applications requiring straight wiring.

The operating temperature of BV-90 and BVR-90 wires does not exceed 90°C; the operating temperature of BV-105 and BVR-105 wires does not exceed 105°C; and the operating temperature of BV and BVR wires does not exceed 70°C. The installation temperature for both wires should be no lower than 0°C.

In short, the main difference between BV and BVR wires lies in their different hardness and flexibility, which results in different application ranges. We simply need to select the appropriate wire based on the specific site requirements. Both types of wire are also commonly used for high-end interior decoration, often used in high-end residential communities and villas.
The BVR and BV wires produced by Qifan Cable both comply with relevant national standards. Notably, Qifan Cable's BV2.5 wires have a wire diameter of up to 1.78mm and a five-star core, surpassing the core quality of many other brands. They offer excellent electrical insulation, mechanical properties, and flame resistance, ensuring reliable quality, convenience, and durability.
Both BV and BVR wires can be customized to meet specific requirements in fire-resistant (NH-BV, NH-BVR), flame-retardant (Z(A, B, C)-BV, Z(A, B, C)-BVR), and flame-retardant and fire-resistant (Z(A, B, C)N-BV, Z(A, B, C)N-BVR).
