RVS wire

The full name of RVS wire is copper core PVC insulated stranded flexible wire for connection, twisted pair multi-strand flexible wire, short for twisted pair, commonly known as "flower wire". At present, this kind of wire is mostly used for fire protection system, also known as "fire wire".    The reason why the letter "RVS" is named is mainly based on the meaning of its English letter. The letter "R" means flexible wire, the letter "V" means PVC, which is its material meaning, and the letter "S" means twisted pair. In fact, in daily life, we are still used to call it flower wire, fire wire, flexible wire, etc. RVS wire is only an official general name.

Purpose of rvs line

Rvs line is mostly used for the detector line of automatic fire alarm system.    Secondly, rvs line is applicable to household appliances, small electric tools, instruments and power lighting lines, power filament, etc.    Double-white core is used to directly connect the lamp cap wire; Different colors of RVS lines also have standard access methods: red and blue cores are used for fire protection, alarm, etc; Red and white cores are used for broadcasting and telephone lines; Red and black cores are used for broadcast lines.    Rvs cable can also be used to connect power amplifier and audio equipment, and broadcast system to transmit audio signals amplified and processed by power amplifier.    RVS structure. Conductor: stranded bare copper wire (BC) or tinned copper wire (TC). Insulation: PVC insulating material

Characteristics of RVS

RVS line is generally used in AC power, but it is also common in DC power.    Properties of rvs lines.  Working temperature: no more than 70 ℃.  Color: white, red-black, red-blue, red-white, etc.  Rated voltage: 450/750V.  Executive standards: GB5023 and JB 8734.3-1998;  Quality standard: 3C certification.  Wire structure: two RV wires (copper wire+PVC insulation) are twisted;    Conductor: It is oxygen-free copper wire or aluminum core (more copper wires), and the insulation is polyvinyl chloride (PVC);

 RVS line series model

ZR-RVS copper-core PVC insulated stranded flame-retardant flexible wire can be used in occasions with flame-retardant requirements;    NH-RVS copper-core PVC insulated stranded fire-resistant flexible wire can be used in occasions with fire resistance requirements;    WDZ-RVS copper-core PVC insulated stranded low-smoke and halogen-free flexible wire can be used in occasions requiring low-smoke and low-halogen.
