Definition and characteristic difference between wire and cable
Nov 30, 2018

Define the difference:
The wire is made up of one or a few soft wires, and the outer bread is covered with a soft cover;
The cable consists of one or several insulated conductor wires, which are covered with a tough outer layer of metal or rubber.
Cables and wires are generally composed of three components: a core wire, an insulating sheath and a protective sheath.

Characteristic difference
Common cable characteristics:
CEF - Ethylene-propylene rubber insulated neoprene sheath, marine flame retardant power cable.
CVV - PVC insulated, PVC sheathed marine flame retardant power cable.
Oxygen cabin wires often use BV, BX, RV, RVV series wires, of which:
BV - copper core PVC insulated wire, long-term allowable temperature 65 ° C, minimum temperature -15 ° C, working voltage AC 500V, DC 1000V, fixedly laid indoors and outdoors, can be applied or dark.
BX - copper core rubber insulated wire, the maximum operating temperature is 65 ° C, applied indoors.
RV - PVC insulated single-core cord with a maximum operating temperature of 65 ° C, a minimum operating temperature of -15 ° C, an operating voltage of 250 V AC, and a DC of 500 V for internal wiring of instruments and equipment.
RVV - copper core PVC insulated and sheathed flexible wire, allowing long-term operating temperature of 105 ° C, working voltage AC 500V, DC 1000V, for wet, high mechanical protection requirements, often moving and bending occasions.
