In fact, the ' wires ' and ' cables ' do not have strict boundaries.

Usually the number of cores, small product diameter, simple structure of the product called Wire, no insulation called bare wire, the other is called the cable; the larger conductor cross-sectional area (greater than 6 square millimeters) is called the large wire, the smaller (less than or equal to 6 square millimeters) is called the small wire, the insulated wire is also called the cloth wire. A wire is made up of one or several soft wires, which are covered with soft, and the cable is made of one or several insulated conductors, and the outer layer is wrapped with a metal or rubber-coated tough shell. Cables and wires are generally composed of three components: core wire, insulated foreskin and protective sheath. Common cable characteristics are as follows: cef--ethylene-propylene rubber insulated neoprene sheath, marine flame-retardant power cable. cvv--PVC insulated, PVC sheathed Marine flame retardant power cable. Oxygen cabin wire is often used BV,BX,RV,RVV series Wire, wherein: bv--copper core PVC insulated wire, the long-term allowable temperature of 65 ℃, the lowest temperature-15 ℃, working voltage AC 500V, DC 1000V, fixed laying in indoor, outside, can be prescribed can also be concealed. bx--Copper Core Rubber insulated wire, the maximum use temperature of 65 ℃, apply indoors. rv--PVC Insulated Single core cord with a maximum operating temperature of 65 ℃, minimum operating temperature of 15 ℃, working voltage AC 250V, DC 500V, used as internal wiring for instruments and equipment. rvv--Copper Core PVC insulated and sheathed soft wire, allow long-term operating temperature of 105 ℃, working voltage AC 500V, DC 1000V, used for damp, high mechanical protection requirements, often moving and bending occasions. In fact, "wires" and "cables" do not have strict boundaries. Usually the number of cores, small product diameter, simple structure of the product called Wire, no insulation called bare wire, the other is called the cable; the larger conductor cross-sectional area (greater than 6 square millimeters) is called a large wire, the smaller (less than or equal to 6 square millimeters) is called the small wire, insulated wire, also known as cloth wire. !! Cables generally have more than 2 layers of insulation, mostly multi-core structure, around the cable tray, the length is generally greater than 100 meters. Wires are generally single-layer insulated, single-core, 100.1-meter-volume, wireless disk. Cable Common models: VV means: PVC insulated (first V), PVC sheath (Second v) YJV22: Xlpe insulated (YJ), PVC sheath (V), steel tape (22) model Plus "ZR" or "FR" for flame-retardant cable (wire). Add "L" to the aluminum wire type is simpler: bvv--PVC insulated and sheathed copper core line, bv--PVC insulated copper core line, byj--copper conductor cross-linked polyolefin insulated wire, bvr--PVC insulated copper soft-hearted line, bx--rubber insulated copper core line, rhf--neoprene rubber sheathed copper soft line.
