How Do Inexperienced People Choose a Good Home Improvement Wire?

August and September are about to enter a small peak of home decoration. Home decoration cannot be separated from wires. Many fires are caused by aging wire lines, unreasonable configuration, or the use of inferior wires. Therefore, choosing good wires is the top priority of decoration. Heavy, the premise of family safety.

What does 2.5 square meters PVC copper cable mean, and how much is appropriate to buy?

To understand, first learn the industry term. "Flat" is an oral term in decoration and hydropower construction, and 2.5 flat is the abbreviation of 2.5 square millimeters, which indicates the cross-sectional area of ​​a single copper wire. The cross-sectional area of ​​the copper wire can determine the current carrying capacity of the wire, and the configuration range of wires with different cross-sectional areas is also different.

Generally speaking, there are 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters and other specifications for home improvement wires, which are used in the following scenarios.

What is the difference between hard wire and soft wire, and how to choose?

Due to different structures, wires are divided into soft wires and hard wires, and the applicable scenarios are also different. The little electrician is here to introduce you to popular science.

BV single-core single-strand hard wire: single-strand copper wire, relatively hard; cheap, generally used for tooling.

BVR single-core multi-strand flexible wire: multi-strand copper wire, which is relatively soft; general home improvement has many bends in the pipe, and its softer characteristics are conducive to laying. It is the first choice for home decoration.

In addition, RV wire refers to a single-core wire with more than 30 copper wires twisted together. It is softer than BVR, and the single-strand wire is thinner. It is generally not used for home decoration.

Therefore, in the process of home decoration, you should choose suitable wires according to your needs, and do not blindly pursue thin or soft wires.

Buy PVC wires and avoid pitfalls!

At present, there are many brands of wires on the market, and the price gap between different manufacturers of a coil of the same specification can reach 20% to 30%. There are many "cut corners" traps in it.

l The trap of copper core "the thicker the better"

At present, the national standard wire requires the use of 99.9% oxygen-free bare copper (red copper), and the price of red copper in the raw material market is tens of thousands of yuan per ton. In order to reduce costs, some bad manufacturers use brass, steel or aluminum as the wire core. Then wrap it with a layer of copper to shoddy. It looks thick and bright on the outside, but it is actually a defective product.

The copper core is thick at both ends and thin in the middle

Some inferior wires have normal wire cores at the front and back ends, but thickened insulation in the middle part, making the copper core thinner than the standard wire core. Such a core current carrying capacity obviously does not meet the standard, and various problems will inevitably occur in long-term use.

Of course, there are endless traps and tricks in the market. It is really difficult to identify them one by one. It is not easy to buy inferior products by choosing regular stores and channels to buy wires.
