Choice of home improvement cables 2

(2) Which type of home improvement cable is better?

There are also many requirements for the insulation layer on the outer side of the cable. There are three main types of cables that many owners choose and use: one is ordinary BV wire, which is plastic copper wire; the other is BVV wire; Fired wire and halogen-free wire, etc. There are many owners of each option.

①: The first choice for home improvement cables is halogen-free wire or flame-retardant fire-resistant wire. Among them, the most common WDN or ZR code wires used by owners. The fire resistance and insulation resistance value of the cable insulation layer are very high. It can be recommended first Choose this kind of wire, but the price of this kind of cable is also relatively high, and owners with a budget can choose.

②: The second choice is the BVV wire. What is the BVV wire, it refers to the wire with PVC insulation and PVC sheath. The BVV wire has one more layer of PVC sheath than the ordinary plastic copper wire. The insulation of the BVV wire is Better. BVV line, when you disassemble its insulation layer, you will find that there is a layer of plastic film inside. At present, BVV line is also used in many families. The price is lower than that of halogen-free line and flame-retardant fire-resistant line. Some, recommended options.

③: The third choice is the BV wire. The BV wire is the most common and the most common plastic copper wire. The outside is a layer of PVC insulation. The BVV wire feels very thin and the wire has no resistance. The function of burning and fire resistance. It is very bad for preventing electrical fires. But the biggest advantage is that the price is cheap.

Selection suggestion: ① For high-rise owners, the suggestion is to choose halogen-free home improvement cables. Because halogen-free cables are even on fireIt will not produce very thick black smoke. In addition, its insulating ability is high. ② When we choose the type of home improvement cable, we should pay attention to the problem of the core, there are soft wires and hard wires. For the circuits laid in the dark, we recommend that you If you choose a hard wire or an exposed circuit, it is recommended that you choose a soft wire. Don't pursue a larger current carrying capacity of the soft wire, it does not make much sense.
