National standard multi-core RVV wire machinery equipment sheathed power cord

RVV wire full name copper PVC insulated PVC sheathed flexible wire, RVV wire cable is two or more RV wire plus a layer of sheath.

1. Meaning of the letter RVV:

The letter R stands for flexible cord, the letter V stands for PVC insulation, and the letter V stands for PVC sheath.

2. RVV wire and cable classification:

Core number from 2 core 24 core between, divided into ordinary type, flame retardant type, low smoke halogen-free type, fire-resistant type, cross-linked type five categories.

3. RVV wire and cable applications:

It can transmit control signals and power signals. It is often used in medium and light mobile appliances, instruments, household appliances, electronic equipment, power lighting, anti-theft alarm systems, building intercom systems, etc.

4. Features of RVV wire and cable:

◆ Flame retardant wire and cable: not easy to catch fire or fire delay is limited to a certain range, suitable for high requirements for flame retardant performance, divided into A, B, C, D and other four levels.

◆ Low-smoke halogen-free wire and cable: It has low smoke and halogen-free, and the use of cables reduces the generation of toxic hydrogen chloride gas and gray black smoke in a large amount during combustion, thus improving the fire safety rate in case of fire.

◆ Fire-resistant wire and cable: In addition to transmitting power under normal working conditions, the cable can still maintain normal operation for a certain period of time when it is on fire, which is suitable for occasions where fire resistance characteristics are required.

◆ Cross-linked wire and cable: XLPE insulation layer, improve the use temperature to 90 degrees Celsius, high temperature resistance, chemical corrosion resistance, good dielectric properties, suitable for complex, harsh environment areas.
