PRODUCT PARAMETER:

BV wire

• Single-core solid wire: It consists of a relatively thick copper conductor and a polyvinyl chloride (PVC) insulating layer tightly wrapped around it. In the cross-sectional diagram, you can see that the center is a solid circular copper conductor, and there is a uniform insulating layer around it. For example, in a common BV wire with a cross-sectional area of 2.5mm², the conductor may be a single copper wire with a diameter of 1.78mm.

RV wire

• Multistranded flexible wire: It is composed of multiple extremely thin copper wires twisted together as the conductor, with a PVC insulating layer wrapped around it. From the cross-section, the center is a mass of twisted thin copper wires surrounded by the insulating layer. For instance, an RV wire with a cross-sectional area of 2.5mm² may be composed of 49 copper wires with a diameter of 0.25mm.

BVR wire

• Multistranded flexible wire: Similar to the RV wire, it also has a conductor made of multiple twisted copper wires. However, the copper wires are slightly thicker than those of the RV wire, and the number is relatively smaller. There is also a PVC insulating layer outside. For example, a BVR wire with a cross-sectional area of 2.5mm² is made of 19 copper wires with a diameter of 0.41mm.

RVV wire

• Multicore flexible sheathed wire: There are multiple RV wires inside. Each RV wire has its own insulating layer, and these core wires with insulating layers are then wrapped by a PVC sheath. In the cross-sectional diagram, you can see multiple small circles (representing the cross-sections of each core wire) distributed within a large circle (representing the sheath), and in each small circle, there are twisted thin copper wires and an insulating layer.
