How To Distinguish Between Cables And Wires?

May 19, 2022

Wire: It is composed of one or several soft wires, covered with a light and soft sheath;


Cable: It is composed of one or several insulated conductors, and the outside is covered with a tough outer layer made of metal or rubber.


Cables and wires are generally composed of three components: core wire, insulating sheath and protective sheath.


The characteristics of commonly used cables 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 chamber wires often use BV, BX, RV, RVV series wires,


BV: Copper core PVC insulated wire, the long-term allowable temperature is 65°C, the minimum temperature is -15°C, the working voltage is AC 500V, DC 1000V.


BX: Copper core rubber insulated wire, the maximum operating temperature is 65 ℃, and it is applied indoors.


RV: PVC insulated single-core flexible wire, the highest operating temperature is 65°C, the lowest operating temperature is -15°C, the working voltage is AC 250V, DC 500V, used for internal wiring of instruments and equipment.


RVV: Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature 105 ℃, working voltage AC 500V, DC 1000V, used in humid, high mechanical protection requirements, frequent movement and bending occasions.
