RVS is a flexible twisted-pair copper wire with PVC insulation, commonly used in low-voltage signal and light-load circuits where installers require neat wiring, reduced tangling, and stable pair management. The twisted-pair structure helps to tightly connect the two conductors, improving installation efficiency and making wiring within buildings and equipment more organized. RVS is widely used in alarm systems, intercom wiring, access control systems, doorbell circuits,
