KVVRP is a copper-core polyvinyl chloride insulated, polyvinyl chloride sheathed, copper wire braided PB control flexible cable. The following is a detailed introduction:

• Structural Features: The conductor is generally composed of multiple strands of fine copper wires twisted together, covered with a polyvinyl chloride insulation layer, then wrapped with a PB layer made of copper wire braiding, and the outermost layer is a polyvinyl chloride sheath. This structure gives the cable good flexibility and PB performance.
• Electrical Performance: The AC rated voltage is generally below 300/500V, suitable for medium and low-voltage electrical control and signal transmission systems. Between conductors, it withstands 1kV for 1 minute without breakdown; between conductor and PB, it withstands 3kV for 1 minute without breakdown. The insulation resistance between each core and the other grounded cores is greater than 10,000 MΩ?km, effectively preventing leakage and signal crosstalk.
• Working Environment Adaptability: The maximum operating temperature of the core does not exceed 70°C, making it suitable for most conventional industrial and indoor environments. The minimum bending radius should be no less than 6 times the cable's outer diameter (without armor layer), and the installation temperature should not be lower than 0°C. It can be installed and used effectively in space-limited and low-temperature environments.
• Application Areas: Widely used in industrial automation, it can be employed for instrument and device connections, distributed control systems (DCS), and control computer connections. It is also suitable for electrical control device connections below AC 500V or DC 100V, such as internal circuit connections in small distribution boxes and control cabinets. Additionally, it is used in industrial and mining enterprises like metallurgy, petroleum, chemical, and power plants as connecting wires for various electrical appliances, instruments, and automated devices. It is also commonly used in places with high electromagnetic compatibility requirements, such as computer rooms and communication base stations.
