RVSP cable and RVS cable differ significantly in several aspects. Below is a detailed comparison of the two:
1. Structure and Components
RVSP Cable
Structure: Conductor - Insulation - Shield - Jacket. RVSP cable adds a copper wire shield to RVS cable, effectively reducing signal transmission loss and shielding against external interference.
Shield: Woven copper wire provides excellent electromagnetic shielding.
RVS Cable
Structure: Conductor - Insulation. RVS cable has a simpler structure and lacks a shield.
Insulation: Made of polyvinyl chloride, it isolates the conductor from the external environment.
2. Application Scenarios
RVSP Cable
It is primarily used in applications requiring high signal transmission requirements, such as field lines, electrical instruments, telecommunications and broadcasting, burglar alarm systems, building intercom systems, video surveillance systems, electronic equipment, and automation devices.
It is suitable for shielded lines for electrical appliances, instruments, meters, electronic equipment, and automation devices with an AC rated voltage of 300/300V or less. RVS Cable
Mainly used for detector circuits in automatic fire alarm systems.
It is suitable for household appliances, small power tools, instruments, and power lighting. For example, the dual white core is used for direct connection to lamp sockets, the red and blue core is used for fire alarms, the red and white core is used for broadcast and communication lines, and the red and black core is used for broadcast lines.
It is used to connect amplifiers to audio equipment and broadcast systems to transmit audio signals amplified by the amplifier.
III. Performance Characteristics
RVSP Cable
It shields against electromagnetic interference and radiation, ensuring high-quality signal transmission.
Due to the added shielding layer, its cost is higher than that of RVS Cable.
RVSP Cable
It has excellent electrical conductivity and flexibility, making it easy to bend and install.
It is relatively low-cost and suitable for general low-voltage electrical equipment.
IV. Nomenclature
RVSP: R stands for soft copper wire, V for PVC insulation, S for twisted pair, and P for shield. Therefore, RVSP cable is a fire-resistant Class C shielded copper-core PVC-insulated twisted-pair cable. RVS: Similarly, R stands for soft copper wire, V for PVC insulation, and S for twisted pair. Therefore, RVS cable is a flame-retardant Class C copper-core PVC-insulated twisted-pair cable.
