The difference between BVR, BV and RV cable
1. The difference between B and R. The former is a fixed wiring cable (wire), and the latter is a flexible wire for connection.
2. The conductor structure of BV, BVR and RV is different. Generally, BV uses the first type of conductor, BVR uses the second type of conductor, and RV uses the fifth type of conductor.
3. BV is usually a single-core wire with a hard conductor, while BVR is a soft conductor, and the two resistance values are the same. RV is softer than them, and the insulation requirements are also different.
What is the difference between BV and BVR cable
1. BV: BV is a single core wire of copper wire, relatively hard, also called hard wire.
2. BVR: This is a single-core wire twisted with multiple strands of copper wire, also called flexible wire.
The difference between RV and BVR cable
1. Different standards: RV conforms to GB/T5023-2008, while BVR is JB/T8734-1999. 2. Different conductor structure: RV uses the fifth type of conductor, which is better than BVR. The second type of conductor should be thinner and have more wires of the same gauge.
3. Different voltage levels: The voltage level of BVR is higher than that of RV.
4. Different insulation thickness: BVR insulation should be thicker.
5. Different uses: RV is mainly used for connecting wires of household appliances, and BVR is mainly used for motors, power distribution cabinets and other places.
Equipment required to produce cable:
