The difference between KVV and RVV wires

2025-08-28 Leave a message

The main differences between KVV and RVV cables lie in their use, structure, and performance.


Applications and Applications


KVV cable: A control cable with excellent resistance to high temperatures, cold weather, and aging. It is primarily used for control and monitoring circuits and protection circuits. It is suitable for use in fixed locations such as urban areas, cable trenches, and pipelines. Flame-retardant, fire-resistant, and low-smoke, halogen-free control cables are available upon request.


RVV cable: A flexible cable, also known as power cable, is suitable for control signal transmission lines, electrical equipment, instrumentation, automation equipment, security and anti-theft alarm systems, high-rise building intercom systems, and home lighting connections. Composed of a single strand of fine copper wire and a small cross-section, it is suitable for applications requiring flexible movement.


Structure and Performance


KVV cable: Consists of a conductor, insulation layer, tape, and sheath. The core conductor has a long-term operating temperature of 70°C, and the ambient temperature during cable installation must be no lower than 0°C. KVV cables have a core count range of 2-61 and are widely used in fixed locations such as urban areas, cable trenches, and pipelines.


RVV cables consist of multiple strands of RV wire, each made of multiple strands of copper wire. The conductor is a twisted strand of fine copper wire. RVV cables have a thinner sheath and are suitable for applications requiring flexible mobility, such as control signal transmission lines and electrical equipment.



Applicable Standards and Voltage Levels


KVV cables comply with GB9330-88 and are generally rated for 450/750V.


RVV cables comply with GB/T 5023-2008 and JB/T 8734-2016, and are generally rated for 300/500V.
