1. RVS is insulated with PVC, while RYJS is insulated with polyolefin.
2. RVS is a relatively common and inexpensive material, while RYJS is a low-smoke, halogen-free, and highly expensive material.
3. RVS is used for twisted-pair cables, while RYJS is used for stranded cables.
1. Type Differences:
RVS is a copper-core, PVC-insulated, sheathed, twisted, shielded flexible cable.
RVS is a standard shielded copper-core, PVC-insulated, twisted, flexible connecting cable.
2. Application Differences:
RVS cable is only suitable for general data transmission over short distances.
RVS is suitable for fixed wiring and connection of power and automation equipment with an AC rated voltage of 450/750V or less. RVS cable stands for copper-core PVC insulated twisted-pair flexible cable for connection, also known as twisted-pair cable, commonly known as "flower wire." Currently, this type of cable is primarily used in fire protection systems and is also called "fire wire."
Applications of RVS twisted-pair cable:
1. Mostly used for detector circuits in automatic fire alarm systems.
2. Suitable for household appliances, small power tools, instruments, and power lighting. The two white cores are used for direct connection to lamp sockets; the red and blue cores are used for fire protection and alarm systems; the red and white cores are used for broadcasting, and the red and black cores are used for broadcasting lines.
How to choose between RYJS and RVS cable:
For general data transmission or home appliance connections, RVS cable is an economical and affordable option.
For applications requiring high fire safety, such as fire protection systems or emergency power lines, RYJS cable is a better choice.
