KVVP Braided Shield Control Cable

Fiber optic cable with multiple thin fibers extending from a black protective sheath, labeled 'KWP'.

Description:

  • KVVP is a PVC-insulated and sheathed braided shield control cable designed for fixed installations requiring reliable signal transmission and electromagnetic interference (EMI) protection.
    It features stranded copper conductors, PVC insulation, a copper wire braid shield, and a PVC sheath, providing excellent shielding effectiveness, durability, and electrical insulation.

  • 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).

Applications:

  • Used for control, monitoring, measurement, and protection circuits in electrical and automation systems requiring stable signal transmission with shielding.

  • Commonly applied in electrical instruments, distribution panels, metering systems, automation, and alarm circuits.
    Suitable for indoor wiring, cable trenches, conduits, and other fixed installations that demand protection against external electromagnetic interference.

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