Description:

  • KVVRP cable is a shielded flexible copper-core control cable with PVC insulation and sheath, designed for control, monitoring, and protection circuits requiring bending movement and anti-interference performance.

  • Manufactured according to GB/T 9330.2 (equivalent to IEC 60227-7: Polyvinyl chloride insulated cables for fixed wiring — Control cables) and GB/T 3956 (equivalent to IEC 60228: Conductors of insulated cables), this cable provides excellent mechanical strength, insulation properties, flexibility, and reliable shielding for safe operation in moving applications.

Applications:

  • Used for control, monitoring, measurement, and protection circuits in systems requiring signal shielding.

  • Widely applied in electrical instruments, distribution panels, automation systems, metering, signal transmission, and alarm systems.

  • Suitable for indoor wiring, control cabinets, cable trenches, conduits, and other flexible installation environments where anti-interference is essential.

  • Ideal for measurement, testing, remote monitoring, computer networking, and control signal systems.
