   In fact, "wire" and "cable" and there is no strict boundaries. Usually less than the core number, the product diameter is small, the structure of a simple product called the wire, no insulation called bare wire, the other known as the cable; conductor cross-sectional area larger (greater than 6 square millimeters) known as large wire, Small (less than or equal to 6 square millimeters) is called a small wire, insulated wire, also known as cloth wire.
   The wire is made of one or several soft wires, with a soft jacket; the cable is made of one or several insulated packets, and the outer packs are coated with a tough outer layer of metal or rubber.     Cables and wires are generally made up of three parts: the core wire, the insulating sheath, and the protective sheath.
   Commonly used cables are as follows:
   CEF - EPR insulated neoprene sheathed, marine flame retardant power cable.
   CVV - PVC insulated, PVC sheathed marine flame retardant power cable.
   OVC cable commonly used BV, BX, RV, RVV series of wires, including: BV - copper core PVC insulated wire, long-term allowable temperature 65 ℃, the minimum temperature -15 ℃, working voltage AC 500V, DC 1000V, fixed laying In the room, the outside can be deposited can also be deposited.
   BX - copper core rubber insulated wire, the maximum temperature of 65 ℃, apply to the room. RV - PVC insulated single-core cord, the maximum temperature of 65 ℃, the lowest temperature -15 ℃, 250V AC voltage, DC 500V, for the internal wiring equipment and equipment.
   RVV - Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105 ℃, working voltage AC 500V, DC 1000V, for wet, mechanical protection requirements, often moving and bending occasions. In fact, "wire" and "cable" and there is no strict boundaries.
   Usually less than the core number, the product diameter is small, the structure of a simple product called the wire, no insulation called bare wire, the other known as the cable; conductor cross-sectional area larger (greater than 6 square millimeters) known as large wire, Small (less than or equal to 6 square millimeters) known as the small wire, insulated wire, also known as the cloth wire that is relatively simple, easy to understand !! Cable generally have more than 2 layers of insulation, mostly multi-core structure, On, the length is generally greater than 100 meters. The wire is generally single-layer insulation, single-core, 100-meter volume, wireless disk.
   Cable common type: VV said: PVC insulated (first V), PVC sheathed (second V) YJV22 said: cross-linked PVC insulated (YJ), PVC sheathed (V) (22) model plus "ZR" or "FR" for flame retardant cable (wire).
   Plus "L" for the aluminum wire model is simple: BVV - PVC insulated and sheathed copper heart line, BV - PVC insulated copper heart line, BYJ - copper core cross-linked polyolefin insulated wire, BVR - PVC insulated copper heart cord, BX - rubber insulated copper heartline, RHF - neoprene copper heart cord.
   (2) small diameter called "line"; diameter called "cable".
   (3) simple structure called "line"; complex structure called "cable".But with the expansion of the scope of use, many varieties of "cable in the line", "cable in the cable." So there is no need to strictly distinguish.In daily habits, people call the household wiring wire, the power cable referred to as the cable.Wire and cable mainly include bare wire, winding wire, power cable, communication cable and cable, electrical equipment.http://www.fuucable.com/
