What sheathed cable sheathed cable usefulness and how many species

 Sheathed cable refers to single or multi-core wire with wire sheathing layer jacketed safer. Is our most commonly used "jacket line", a layer of white PVC jacket, which sets a few BV line. This line is usually a copper wire, in addition to outside the outer layer of insulation wire, outside the wire as well as a protective layer. How many types of sheathed cable: BVVB full name of PVC insulated wire flat cable, commonly known as hard-sheathed cable .RVV PVC insulated copper wire sheathed cable, commonly known as a soft jacket line. Including RVV sheathed cable wire (soft jacket line) and BVV wire (hard sheathed cable), BVVB electrical wiring. BV, BVV, BVVB, BVR power line: In simple terms: vv two terms refer to the wire, PVC sheath; BV PVC insulated copper single line; BVV, poly vinyl jacket exposed copper wire, two-wire cable; BVVB poly vinyl jacket exposed copper wire, cored wire; B series categorize belong wire cloth, voltage: 300 / 500V, V is PVC polyvinyl chloride (plastic) L representative of aluminum, R is ( soft) means, in order to soft, is to increase the number of conductor PVC insulated copper wire BV, BLV core, PVC insulated wire, BVR conductor PVC insulated flexible wire, wire above structure: Conductor + insulation ; RV core PVC insulated flexible wire connection, softer than BVR, 49 cases RV2.5 is 0.25mm copper wire, RVV Tongxin PVC insulated flexible wire connection, more than a RV layer plastic sheath. "Sheathed cable" BVVB conductor PVC insulated and sheathed flat cable, is 2 BV line, add a layer of white jacket. Sheathed cable usefulness: mainly used in electrical, instrumentation and electronic equipment, and automatic generation of device power lines, control lines and signal transmission lines, concrete can be used for anti-theft alarm system, building intercom system.
