Why are the copper wires in the wires wrapped together like copper wires like hair?
On the market are now common cloth, wires have BV, BVR, there used to be BLV.The B series are classified as cloth wires, so start with B, voltage: 300/500V
1. of the same section of the single wire is simple, more soft wire structure with low cost, low price. Soft cloth wires are much higher.2. because of the skin effect of the current, the conductive power of the multiple wires of the same cross section is stronger than that of the single wire.3. general wiring in general use single shares, with special requirements on occasions to use multi strands or soft cloth wire. For example, traveling with cloth, wires, regardless of the size of the section, are using BXR (copper core rubber insulated flexible wire).4. more strands or soft cloth wires are easier to wear than wire strands. This is also one of the reasons for the use of soft cloth wires for driving.According to the above characteristics, regardless of the expensive cost, only considering the electrical conductivity and durability, safety, etc., or more than single wire is much better than single wire.
V is PVC PVC, that is (plastic)L is the code for the aluminum core"R" means "soft". To be soft is to increase the number of conductorsBV: copper conductor PVC insulated wireBLV: aluminium conductor PVC insulated wire
