KVVR Flexible Control Cable

A black electrical cable with multiple color-coded wires visible at the open end.

Description:

  • KVVR cable is a flexible PVC-insulated and sheathed control cable designed for control, monitoring, and protection circuits in fixed or flexible installations.

  • Manufactured according to GB/T 9330.2 (equivalent to IEC 60227-7: Polyvinyl chloride insulated cables for fixed wiring — Control cables), this cable provides excellent mechanical strength, electrical insulation, flexibility, and safety in motion applications.

Applications:

  • Used for control, monitoring, measurement, and protection circuits

  • Commonly applied in electrical instruments, distribution devices, metering, signal transmission, automation, and alarm systems

  • Suitable for indoor wiring, cable trenches, ducts, and other flexible installations

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

Technical Specifications:

  • Rated Voltage: 450/750V

  • Test Voltage:

    • Insulation ≤ 0.6 mm: 2000V

    • Insulation > 0.6 mm: 2500V

    • Outer sheath test: 3000V

  • Standards: GB/T 9330.2 (equivalent to IEC 60227-7)

  • Conductor: Class 5 stranded copper conductors per GB/T 3956

  • Insulation: Flexible PVC/D-type PVC for movable applications

  • Color Code:

    • For cables with five or more cores — black cores with white number printing (1, 2, 3...) arranged clockwise from the inner to the outer layer

    • Yellow-green grounding conductor included in the outer layer

  • Core Structure: Interstices filled; optional isolation wrapping (PP tape or nonwoven fabric); non-sticky insulated cores

  • Sheath: PVC/ST5 outer sheath, black (RAL9005) or gray (RAL7001)
