The power line a current transmission wire, an outer sheath, the inner sheath copper wires.
Full name copper core PVC insulated PVC sheathed flexible cable. RVV line, the appearance of the round shape, the number of cores is more, and there are strands between the two cores. R stands for the cord and the letter V stands for the insulator polyvinyl chloride (PVC). Main use of RVV cable: It is applied to power lines, control lines and signal transmission lines that do not need to be shielded, such as electrical appliances, instruments and electronic equipment, and automation devices.
Commonly used RVV wire types are: RVV2*0.5, RVV2*0.75, RVV2*1.0,
such as: RVV2*1.5 ——2 means 2 cores, 1.5 means the cross-sectional area of one core (unit is mm2)
Full name copper core PVC insulated polyvinyl chloride shielded flexible cable. It is suitable for communication, audio, broadcasting, audio system, anti-theft alarm system, intelligent automation system, automatic meter reading system, fire protection system, etc. It needs anti-interference line connection, efficient and safe transmission data cable. The letter R stands for the cord, the letter V stands for the insulator polyvinyl chloride (PVC), and the letter P stands for the shield. RVVP can be used specifically for monitoring systems, access control systems, building video intercom systems, and control lines in building control systems.
