RVS flexible wire is a type of twisted pair cable commonly used for low‑voltage and control applications. It consists of two insulated flexible conductors twisted together in a regular pitch. The conductors are usually made of high‑purity stranded copper, providing excellent electrical conductivity and mechanical flexibility. Each core is insulated with durable PVC, typically in contrasting colors such as red/white, red/black, or blue/white for easy identification during installation and maintenance.The twisting structure of RVS flexible wire helps to reduce electromagnetic interference and crosstalk between circuits. By pairing the conductors and twisting them along the cable length, induced noise from external sources is minimized, which is especially beneficial in environments with multiple control lines, alarm systems, or audio circuits. This configuration also makes routing and bundling easier, as the two conductors remain organized as a single cable.RVS flexible wire is widely used in fire alarm systems, emergency broadcast systems, intercoms, household wiring for lamps and switches, and various control circuits. In fire alarm and security systems, it often connects detectors, sounders, and control panels, where reliable signal transmission at low voltage is essential. Its flexibility allows it to be drawn through conduits, trunking, and tight corners without damage to the conductors or insulation.The wire is generally rated for standard low‑voltage AC applications, commonly up to 300/300 V or 300/500 V, depending on construction and regional standards. Operating temperature ranges typically fall between −15 °C and +70 °C for ordinary PVC insulation, with some variants designed for slightly higher temperature resistance. The insulation provides adequate dielectric strength and resistance to common household chemicals, moisture, and moderate mechanical stress.Standard sizes range from about 0.5 mm² to 2.5 mm² in conductor cross‑section, with the most popular sizes around 0.75 mm² and 1.0 mm² for lighting and control. The stranded structure of the copper cores gives the wire a soft, pliable feel, making it suitable for installations where frequent bending or movement may occur. Stranding also improves vibration resistance compared with solid conductors.RVS flexible wire is typically produced in coils or reels, allowing installers to cut custom lengths on site. Markings on the insulation or packaging usually indicate conductor size, voltage rating, and relevant standards. When installed correctly and protected from direct mechanical damage or extreme environmental conditions, RVS flexible wire provides a cost‑effective, reliable solution for signal and power transmission in a wide variety of residential and light commercial applications.
