Jack knowledge about cable:Distinguish between wire and cable

People often think of wire and cable be confused, the Jack will give you the difference between the wire and cable!

Wire
Carrier conduction electricity use.

Wire and cable
For transmission (magnetic) energy, information and realize electromagnetic energy conversion of wire products.

Distinguish between wire and cable

The wire is composed of one or a plurality of soft wire, wrapped with a protective layer of light; cable is composed of one or a plurality of insulating coating wire, wrapped with metal or rubber tough outer. Cables and wires are generally consists of a core wire, insulating sheath and the protecting scarfskin consists of three parts. The following characteristics of common cable: CEF — ethylene propylene rubber insulated rubber chloroprene, flame retardant power cable for ship. CVV — PVC insulation, flame retardant power cable with PVC sheath for ship. Oxygen line often use BV, BX, RV, RVV series wire, wherein: BV — copper core PVC insulated wires, long-term permissible temperature 65 ℃, the lowest temperature of -15 ℃, working voltage 500V AC, DC 1000V, fixed laid indoor, outside, can be laid can also be concealed. BX — copper core rubber insulated wire, the highest use temperature is 65 ℃, apply to indoor. RV — Polyvinyl chloride insulated single core cable, the highest use temperature is 65 ℃, the minimum temperature -15 ℃, working voltage 250V AC, DC 500V, used as a instrument and equipment internal wiring. RVV — copper core PVC insulated and sheathed flexible cords, allowing long-term working temperature is 105 ℃, the working voltage 500V AC, DC 1000V, used in wet, mechanical protection requirements high, often moving and bending of the occasion. In fact, “the wire” and “cable” and there is no strict boundaries. Usually the core number less, products with small diameter, simple structure of the product called wires, no insulation called bare wire, the other called cables; conductor cross-sectional area of the larger (greater than 6 mm2) called the high wire, the smaller (less than or equal to 6 mm2) called small wires, insulated wire, also known as wire cloth that is relatively simple, easy to understand!! cable generally have 2 layers of insulation, most of them are multi core structure, around the cable tray, usually more than 100 meters in length. The wire is usually single layer insulation, single core, 100 meters roll, radio disc. Cable common type: VV said: PVC insulated (first V), PVC sheath (second V) YJV22 said: crosslinking PVC insulation, PVC sheath (YJ) (V), steel tape armored (22) and add “ZR” or “FR” for flame retardant cable (wire). Add “L” to aluminum wire type is simple: BVV– PVC insulated and sheathed copper core PVC insulated copper wire, BV–, BYJ– copper core crosslinked polyolefin insulation wire, PVC insulated copper wire BVR–, BX– rubber insulated copper wire, RHF– chloroprene rubber copper core wire.

(2) small diameter called “line”; large diameter is called “cable”.

(3) is called the “line” has the advantages of simple structure; complex called “cable”.

But with the expanding usage, many varieties of “line cable”, “cable cable”. So there is no need to distinguish strictly.

In daily habits, the household cloth wire is house wire, the power cable referred to as cable.

Wire and cable mainly includes bare wire, winding wires, power cables, communication cables and optical cables, electrical equipment with.
