"Wiring cable"-known as such in Chinese-derives its name from its specific application in fixed wiring installations. Also referred to as insulated wire, this type of cable is primarily utilized for fixed wiring layouts and for making flexible connections to electrical appliances, hence its designation. Constructed from multiple strands of fine copper wire woven together and encased in an insulating outer layer, these cables boast exceptional current-carrying capacity and safety performance.
The nomenclature of wiring cables is inextricably linked to their function. "Wiring" refers to the systematic classification of cables-based on criteria such as function and voltage levels-and their subsequent arrangement according to established protocols, involving the rational planning of the routing and pathways for each specific line. Wiring cables are predominantly employed in residential renovation projects-serving as both main supply lines and branch circuits-to provide power to various household appliances, including lighting fixtures, power outlets, air conditioners, and water heaters.
The various types of wiring cables include models such as BV, BVR, RYJ, and RVS. The BV cable is a copper-core, PVC-insulated wire designed for fixed wiring installations; the BVR cable is a copper-core, PVC-insulated flexible wire, frequently utilized in applications requiring pliability and bendability; the RYJ cable features a polyolefin insulating layer, endowing it with eco-friendly properties; and the RVS cable is designed for twisted-pair connections, making it particularly well-suited for scenarios demanding high flexibility-such as in fire safety wiring systems.
