RVV sheathed flexible wire, multi-core copper core power cord, national standard, full meter bending resistance

Description :

This RVV cable is a typical PVC insulated PVC sheathed flexible cable, commonly known as sheathed wire. Mainly used for power lines, control lines, and signal transmission lines in electrical appliances, instruments, electronic equipment, and automation devices. The conductor is made of multiple strands of thin copper wire twisted together, which has good flexibility and is convenient for wiring in narrow spaces or scenes that require frequent movement. The outer skin is thick, wear-resistant, and has a certain degree of tensile resistance, suitable for indoor fixed installation or light mobile use.

Pay attention to distinguishing between the number of cores and wire diameter when purchasing. Common specifications range from 2 cores to tens of cores, with wire diameters covering mainstream ranges from 0.5 square to 6 square. This type of cable does not come with a shielding layer, so it is not suitable for strong interference environments. However, it has low cost and high cost-effectiveness, making it a common choice for connecting ordinary household appliances, lighting circuits, and monitoring power lines. It is recommended to perform tinning treatment or use specialized terminals at the joint to prevent the copper wire from scattering and causing poor contact.

During acceptance, check whether the meter mark is clear, whether the insulation layer thickness is uniform, and whether the conductor color is standard (such as red for live wire, blue for neutral wire, and yellow green for ground wire). This cable from the Jiukai brand complies with the national standard GB/T 5023, with low electrical resistivity, stable conductivity, low long-term heat generation, and more secure safety. Whole roll packaging, sufficient length, no shortage of rice, suitable for engineering bulk procurement or store retail stocking. Avoid direct sunlight and high temperature and humidity during storage to prevent the outer skin from aging and hardening.
