Copper Conductor, PVC Insulated and Sheathed, Steel-tape Armoured Control Cable

RVS cable is called copper core polyvinyl chloride insulated layer twisted copper wire connection, twisted multi-core soft wire. It is a twisted multi-strand soft wire, usually called twisted pair or flower wire. RVS cable is mainly used in fire protection system, so it is also called fire protection line.

The structure of RVS cable includes conductor, insulation layer and twisting structure. Its conductor is multi-core annealed bare copper twisted, and the insulation layer is polyvinyl chloride (PVC). This structure makes RVS cable have good softness and flexibility, suitable for a variety of application scenarios. ‌

RVS cable is widely used in many fields. It is mainly used in fire protection systems, such as detector lines of fire automatic alarm systems. In addition, RVS cable is also suitable for household appliances, small power tools, instruments and meters, and power lighting lines. Double white cores are used for direct connection to lamp head wires, red and blue cores are used for fire protection, alarm, etc., red and white cores are used for broadcasting and telephone lines, and red and black cores are used for broadcasting lines. ‌

The main difference between RVS cable and RVSP cable lies in structure and application. The structure of RVS cable is conductor-insulation, while the structure of RVSP cable is conductor-insulation-shielding-sheath. RVS cable is suitable for detector lines, household appliances, small power tools, etc. of fire alarm system, while RVSP cable is mainly used in field lines, electrical instruments, telecommunications broadcasting, anti-theft alarm system and other occasions that require shielding.

The rated voltage of RVS cable is 300/300V, and the normal operating temperature does not exceed 70℃‌.

When installing and laying RVS cable, avoid excessive stretching, twisting or mechanical damage. Make sure that the cable has no sharp bending radius during installation to avoid damaging the internal structure of the cable. In places where mechanical damage may occur, additional protection measures should be provided, such as the use of cable troughs, conduits, etc. ‌

Check the appearance of the RVS cable regularly to find signs of breakage, aging or damage in time. Check the insulation performance of the cable and perform insulation resistance test if necessary. Keep the cable and its surroundings clean to avoid the accumulation of debris such as oil, dust, etc. For any problems found, repair or replace them in time‌.

When using RVS cables, consider their environmental conditions, such as temperature, humidity, and chemical corrosion. Avoid exposing the cable to sunlight or extreme temperature environments to reduce the aging rate. In environments where there may be a risk of fire, cables that meet the fire protection grade requirements‌4 should be used.

Common faults include poor contact, overheating, and circuit breakage. The treatment method includes ensuring that the cable connection and wiring are correct and firm to avoid heating or circuit breakage caused by poor contact. The terminal should match the cable specifications and use appropriate wiring tools‌.

When purchasing RVS cables, you should choose cables with appropriate specifications according to the use environment and load requirements, including conductor cross-sectional area, insulation material and sheath type. Make sure to purchase products that meet relevant standards and certifications to ensure their quality and performance‌.
