KVV PVC Sheathed Control Cable

A fiber optic cable with a black connector and multiple thin wire strands at the end, lying against a black background.

Description:

  • KVV is a PVC-insulated and sheathed control cable designed for fixed installation in control, monitoring, and protection circuits.

  • It features copper conductors, PVC insulation, and a durable PVC sheath, providing excellent mechanical strength, insulation performance, and flame retardancy for reliable signal transmission in fixed wiring systems.

  • Manufactured in accordance with 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 instruments, distribution panels, metering, signal transmission, automation, and alarm systems.

  • Commonly installed indoors, in cable trenches, conduits, or other fixed environments where flexibility is not required.
    Ideal for measurement, testing, remote monitoring, computer networking, and signal control systems.
