We are a Power Cord Manufacturers, let me introduce the difference between power cord and cable.

　　The power cord is composed of one or several soft wires, covered with a light and soft sheath;

　　The cable is composed of one or several insulated conductors, which are 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, among which: BV - copper core PVC insulated wire, long-term allowable temperature 65 ℃, minimum temperature - 15 ℃, working voltage AC 500V, DC 1000V, fixed laying Indoor or outdoor, it can be applied lightly or darkly. BX——Copper core rubber insulated wire, the maximum operating temperature is 65℃, applied indoors.

　　RV——PVC insulated single-core flexible wire, the highest operating temperature is 65℃, the lowest operating temperature is -15℃, 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, long-term working temperature is 105℃, working voltage is AC 500V, DC 1000V, it is used in places where humidity, high mechanical protection requirements, frequent movement and bending. Actually, "power cord" and "cable" do not have strict boundaries. Usually, products with a small number of cores, a small product diameter and a simple structure are called wires, those without insulation are called bare wires, and the others are called cables; those with a larger conductor cross-sectional area (greater than 6 square millimeters) are called large wires. Small (less than or equal to 6 square millimeters) are called small wires, and insulated wires are also called cloth wires. This is relatively simple and easy to understand!! Cables generally have more than 2 layers of insulation, most of which are multi-core structures, which are wound around the cable reel. , the length is generally greater than 100 meters. Wires are generally single-layer insulation, single-core, 100 meters in a roll, without a reel.

　　Common types of cables: VV means: PVC insulation (first V), PVC sheath (second V) YJV22 means: Cross-linked PVC insulation (YJ), PVC sheath (V) , Steel belt Kay installed (22) model plus "ZR" or "FR" is a flame retardant cable (wire). Add "L" for aluminum wire The model of the wire is simpler:

　　BVV-- PVC insulated and sheathed copper core wire,

　　BV-- PVC insulated copper core wire,

　　BVR - PVC insulated copper core flexible wire,

　　BX - rubber insulated copper core wire,

　　RHF - neoprene sheathed copper core flexible wire.
