Common sense of wires and cables

It is very easy to confuse the differences between wires and cables. The cable filling paste manufacturer asked if there are any problems you haven't made clear before?

Difference between No. 1 low smoke halogen-free cable and environmental protection cable

Environmental protection cables refer to wires and cables that do not cause harmful substances, harmful halogen bulb vapor, corrosive vapor, high fever when ignited, and do not pollute the soil layer.

Low smoke halogen-free cable, which is not easy to emit thick smoke of halogen acid vapor when ignited.

Low smoke halogen-free cable is only one type of wire and cable, in other words, its characteristics. Theoretically, low smoke halogen-free wires and cables are not necessarily environmental protection wires and cables, and environmental protection wires and cables must be low smoke halogen-free wires and cables.

Difference between No.2 flame retardant cable and insulated wire

Flame retardancy refers to preventing and slowing down the diffusion of flame along the cable so that the fire accident does not expand. This kind of cable has a certain self extinguishing energy after leaving the open fire.

Fire prevention means that it will maintain continuous power supply for a certain time when the flame is ignited, that is, to maintain the consistency of power supply circuit. This kind of cable has the working capacity of power supply system for a certain time in the flame.

No.3. Difference between bv copper core cable and BVR copper core cable

Bv copper core cable is a single core hard electric conductor cable. Advantages: long service life, not easy to air oxidation due to small outer circle area / section ratio, and resistance to short-circuit capacity impact.

BVR copper core cable is a multi copper core cable with a large number of electrical conductors, reducing the diameter of each wire. Advantages: because the wire is too soft, it is often used in power consumption places of theme activities and temporary power consumption places, and the equipment, dragging and moving are convenient.
