Decoration Home Wire with BvR Wire? Or with BV Wire?

The improvement of living standards in today's society and the increased use of household appliances, people's demand for electricity is growing, and the use of home furnishing wire has increased. Now the market wire brands, the face of a wide range of wire, I believe that most common consumers will be baffled. However, the quality of the wire is directly related to the safety of people's lives and property, so the choice of wire for home furnishing should not be sloppy. What kinds of wires are there in the decoration?

Today we will be popularized with BvR wire for home decoration? Or BV wire?

Do not consider the cost of home improvement, with flame retardant BVR cable is good, if the home decoration with flame retardant PVC pipe pre-buried in the wall, you can also use ordinary copper-core BV wire, even after years of use, want to replace the wire is also very simple, the old wire out, the new wire buried in it. If there is wood in the ceiling, it is best to also use fire-retardant tube sheathed BV wire is the safest.

Hard wire can generally be called BV wire

BV wire is mainly used for power supply, lighting, outlets, air conditioning, for AC voltage 450/750V and below power devices, daily appliances, instruments and telecommunications equipment with the general BVR cable wire. Softer cables have a certain degree of softness, in terms of folding, straightening will be more convenient.

Soft wire → can also be called BVR wire

BVR wire is suitable for AC voltage 450/750V and below power devices, daily appliances, instruments and telecommunications equipment with cable and wire that is BVR cable, such as distribution boxes. Soft wire relative to hard wire production complex, high-frequency circuits in the soft wire than hard wire load capacity, plus, the price of soft wire relative to the same specification hard wire expensive.

How to choose the wire in the home?

Wire selection is not convenient to use, and there is a huge potential for electricity safety. Next, we will share with you how to choose a more practical wire in the home improvement.

First of all, we have to go to a classification of wires, we can be divided into BV wire, BVR wire, BVVB wire, RVV wire in the home furnishing wire. Home furnishing wire BV, BVR, RV, are single-core wire

BV wire is a single-core copper wire, relatively hard, also called hard wire; BVR cable is a lot of strands of fine copper wire stranded together in a single-core line, also called soft wire; RV wire is still soft wire, is more strands of copper wire stranded together in a single-core line, home furnishings generally do not use; BVVB wire is hard sheathed wire, that is, two or three BV wire sheathed together; RVV line → is a soft sheathed line, also a root Two three or four RV wire, with a sheath set together.

According to the fire function is divided into general wire and fire-retardant wire; wire model before the ZR letter symbol for the prefix, such as ZC-BV, said the fire-retardant wire, as the name implies, can prevent burning. Generally used in dense places, energized cable dense places. Prefix "ZR" letters, which means flame retardant, wire and cable flame retardant level A, B, C three, ZB on behalf of the B flame retardant, ZR silent thought C level flame retardant. Flame retardant characteristics ZA>ZB>ZC, either home furnishing wire or power cable will have the difference between flame retardant.

Comprehensive BV and BVR cable advantages and disadvantages of both, we recommend that you choose ZR-BV wire, because it is flame retardant wire. Secondly, we have to look at the specifications of the wire. Then we use in home decoration to the wire specifications.

Basically, there are two kinds: one is 2.5mm2 square, one is 4mm2 square; then the living room, bedroom, some lighting switches and sockets are generally used BVR cable, we choose to use 2.5mm2 on the line, like refrigerators, kitchens, bathrooms, air conditioners and some other high-powered use of electrical appliances in some places, we have to go alone to go 4.0mm2 wire.

So how do we go about buying a good wire?

Firstly, we look outside the BVR cable packaging, first we have to look at the packaging above, if they are national standards, than they J An to / E No home C this certification, if the European standard, we have to recognize the EU CE certification mark; in fact, we have to look at a certificate of conformity, the product model, product specifications, the date of delivery, the rated voltage and so on.

Then the second look at the color of the copper wire in the copper core of the BVR cable, the color should be purple-red, and shiny, and bend the copper core wire should be soft, should not be elastic, if elastic, it means that the copper core wire material contains other impurities.

Thirdly, we have to look at the insulator of a BVR cable, we can use a lighter to burn the outer skin of the wire, if it says it this head burn for 5-10 seconds, if there is no burning words, it proves that he is a very good material of flame retardant insulation BVR cable.

Home renovation is a seemingly simple, but actually very troublesome thing in the home, so be sure to choose the best option according to their own economic conditions. The above is a personal experience, we are XSD Cable manufacturers.
