Wire is composed of one or several soft wires, coated with a soft sheath; A cable is made up of one or more insulated conductors wrapped in a tough outer layer of metal or rubber. Cables and wires are generally composed of three parts: core wire, insulating sheath and protective sheath. Common cable characteristics are as follows: CEF - ethylene propylene rubber insulated neoprene sheathed, Marine flame retardant power cable. CVV - PVC insulated, PVC sheathed flame retardant power cable for Marine. Oxygen chamber wire often uses BV, BX, RV, RVV series wire, including: BV - copper core PVC insulated wire, long-term allowable temperature 65℃, the minimum temperature -15℃, working voltage AC 500V, DC 1000V, fixed in the indoor and outdoor, can be bright or dark compress. BX -- copper core rubber insulated wire, the maximum operating temperature of 65℃, applied indoors. RV -- PVC insulated single core flexible wire, maximum operating temperature 65℃, minimum operating temperature -15℃, working voltage AC 250V, DC 500V, used for internal wiring instruments and equipment. RVV -- copper core PVC insulated and sheathed soft wire, allowing long-term operating temperature 105℃, operating voltage 500V AC, 1000V DC, for wet, mechanical protection requirements, often moving and bending occasions. In fact, there is no strict line between "wire" and "cable". Usually the core number is less, the product diameter is small, the structure of the simple product is called wire, no insulation is called bare wire, the other is called cable; The conductor with a larger cross-sectional area (greater than 6 square millimeters) is called a large wire, the conductor with a smaller cross-sectional area (less than or equal to 6 square millimeters) is called a small wire, and the insulated wire is also called a cloth wire. This is relatively simple, easy to understand! Cables generally have more than 2 layers of insulation, most are multi-core structure, wound on the cable tray, the length is generally greater than 100 meters. Wires are generally single insulated, single core, 100 meters a roll, wireless disk. Common cable models: VV means: PVC insulation (the first V), PVC sheathed (the second V); YJV22 said: cross-linked polyethylene insulation (YJ), polyvinyl chloride sheathed (V), steel belt mounted (22) model plus "ZR" or "FR" for flame retardant cable (wire). Add "L" for aluminum wire. The models of wire are simple: BVV-- PVC insulated and sheathed copper core wire, BV-- PVC insulated copper core wire, BYJ-- copper core crosslinked polyolefin insulated wire, BVR-- PVC insulated copper core wire, BX-- rubber insulated copper core wire, RHF-- chloroprene rubber sheathed copper heart wire. A wire is a wire that transmits electrical energy. Split bare wire, electromagnetic wire and insulated wire. Bare wire has no insulation layer, including copper, aluminum flat wire, overhead stranded wire and various profiles (such as profile wire, bus, copper bar, aluminum bar, etc.). It is mainly used for outdoor overhead and indoor confluence bar and switch box. An electromagnetic wire is an insulated wire that generates a magnetic field after being energized or induces a current in the magnetic field. It is mainly used for motor and transformer winding and other related electromagnetic equipment. Its conductor is mainly copper wire, should have a thin insulating layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties. Different insulation materials can be used to obtain different characteristics. A wire is a wire that transmits electrical energy. Split bare wire, electromagnetic wire and insulated wire.
