Differences between RVVP and KVVRP Cables
2025-08-29
The main differences between RVVP and KVVRP cables lie in their designations, voltage ratings, conductor construction, implementation standards, and application scenarios. RVVP is suitable for 300/300V low-voltage interference-resistant lines, while KVVRP is suitable for 450/750V shielded control applications.
Key Differences Comparison
Name and Definition
RVVP: Copper-core PVC insulated, PVC sheathed, copper braided shielded flexible cable. This is an electrical connection cable with interference-resistant features.
KVVRP: Copper-core PVC insulated, PVC sheathed, braided shielded, flame-retardant Class C control flexible cable. It is designed for areas with high signal interference.
Voltage Ratings
RVVP is rated for 300/300V or 300/500V and is suitable for low-voltage environments.
KVVRP is rated for 450/750V and is suitable for higher-voltage control circuits.
Conductor Structure
RVVP uses a multi-stranded copper wire conductor with excellent flexibility, making it suitable for mobile installations.
KVVRP uses a single rigid copper wire or multi-stranded BV rigid wire, offering a more robust structure and suitable for fixed installations.
Applicable Standards
RVVP complies with JB/T8734.5-2012.
KVVRP complies with GB/T9330-2008.
Application Scenarios
RVVP: Mobile or close-spaced applications requiring interference resistance, such as communications, audio broadcasting, and security monitoring.
KVVRP: Fixed applications with high electromagnetic interference, such as indoor signal control and monitoring circuits.
Other Differences
Shielding Performance: Both include a braided copper shield, but KVVRP emphasizes flame retardancy (Class C).
Bending Radius: Due to its greater flexibility, RVVP has a minimum bending radius of 15 times the outer diameter, while KVVRP typically requires a minimum of 12 times the outer diameter.
