The full name of RVS wire: copper core PVC insulated twisted wire for connection, twisted multi-strand flexible wire, referred to as twisted pair.
RVS twisted pair wire is commonly known as "flower wire". At present, this type of wire is mostly used in fire protection systems, also called "fire protection wire".
The letter S stands for twisted pair, the letter R stands for soft wire, and the letter V stands for polyvinyl chloride (insulator)
The use of RVS twisted pair:
1. Mostly used in detector lines of automatic fire alarm systems.
2. Suitable for household appliances, small electric tools, instruments and power lighting wires. The double white core is used to directly connect the lamp holder wire; the red and blue core is used for fire protection, alarm, etc.; the red and white core is used for broadcasting and telephone lines; the red and black core is used for broadcasting lines.
3. Used to connect power amplifiers to audio equipment and broadcast systems to transmit audio signals amplified by power amplifiers.
Compared with 2*1.5mmRVS, the advantage of 2*1.5mm ZC-RVS is that it does not delay combustion during combustion and can be applied to occasions with fire protection requirements.
Structure
Conductor: Stranded bare copper wire or tinned copper wire
Insulation: flame retardant PVC insulation material
Insulation color: red blue, red black, red white, etc.
Usage characteristics:
Rated working voltage: 300/300V
The long-term allowable working temperature of the cable is not higher than 70°C.
When a short circuit occurs (the duration does not exceed 5 seconds), the temperature of the cable conductor does not exceed 160°C.
The ambient temperature during cable laying should not be lower than 0°C, otherwise preheating is required.
We have other wire such as solar cable、thhn cable、 3x6mm2 flexible cable、cable flexible 3x10、flexible special cable、high flexible cable and so on.
