Introduction to common wire models derived from BV wires and RV wires

The most familiar things in life are probably the various types of electrical wires, including hard wire, flexible wire, and twisted-pair wire. Wires are much simpler in structure than cables, and their applications are closely related to everyday life. Below, we will introduce the common types of wires derived from BV and RV wires.


I. BV-Type Wire Models and Structure


Models include: BV, BVR, BVS, BVV, BVVR, BVVB, BX, ZRBV, and NHBV


BV wires have a simple structure, consisting of a single core and an insulation layer. Some also have a sheath. The sheath is made of polyvinyl chloride and is also designated by the letter V. For example, BVV stands for copper-core, polyvinyl-insulated, and polyvinyl-sheathed round wire.


II. RV-Type Wire Models and Structure


Models include: RV, RVB, RVS, RVV, and RVVP


RV is a traditional single-core flexible wire, consisting of multiple strands of fine copper wire twisted together and covered with an insulating protective layer. It features a simple structure, good conductivity, and safe electrical insulation. It is a commonly used fixed wiring cable for home decoration.


3. Coaxial Cable


Common coaxial cable types include RG-6, RG-8, and RG-58.


4. HYV Series Telephone Cable


PVC Insulated Speaker Cable


Single Category 5 2-Pair Unshielded Network Cable


The model number structure of wires is much simpler than that of cables. The model number plus ZR or NH indicates flame-retardant or fire-resistant wire, and the model number plus L indicates aluminum core wire.
