PVC insulated PVC sheathed flexible cable.
The letter R represents a flexible cord
The letter V represents insulation polyvinyl chloride (PVC)
RVV wire is a commonly used cable in weak current systems, with an indefinite number of core wires, two or more, and an outer PVC sheath. There are no special requirements for the arrangement of core wires.
For example, rvv2 * 0.5 refers to two wires with an area of 0.5 square millimeters and an outer sheath. The purpose of the sheath is to
1. Protect the inner protective layer of the cable from mechanical damage and chemical corrosion;
2. Enhance the mechanical strength of the cable.
RVV refers to multi strand copper core flexible wire, which looks like the markings on the wire and the thickness of the skin compared to the core The cortex is usually made of polyvinyl chloride material The copper core is twisted into 19 strands The specifications generally include 1, 1.5, and 2.5 square millimeters When looking at the length of the line (100 meters per circle), the national standard line is 95-100 meters, and the non-standard line is about 90 meters
The formula for the area of a circle is: radius x radius x 3.14 (pi).
The diameter and number of single filaments of BVFlexible Cable RVV RVVP RVVB Model Complete Professional Ordering
For BV2.5, the national standard diameter is 1.78mm, and the radius is 0.89mm.
Therefore, the cross-sectional area is 0.89 × 0.89 × 3.14=2.487194, which is approximately equal to 2.5mm² /Square millimeters.
Similarly, 1-6 square meters are all single core diameters, and 10 square meters or more are multi-core. Please refer to Appendix 1 for details.
