After the renovation into the hydropower transformation stage, many owners will fall into a misunderstanding: they always feel that the thicker the wires at home, the better, so as to greatly ensure the safety of electricity, so as not to short-circuit, tripping and other accidents. But have you ever thought that thick wire is a good thing? Won't it raise new circuit safety issues? The correct choice of wire, cable to take you to understand these knowledge points.

The cross-sectional area of the wire

In popular terms, it is according to the thickness of the wire division, common 1.5 square, 2.5 square, 4 square lines and 6 square lines, the larger the cross-sectional area, the greater the capacity of the wire, the higher the price.

If the choice is improper, there will be two results: using a thin wire to carry an electrical appliance higher than its carrying capacity will cause the line temperature to be too high and fuse the copper core, and seriously it will ignite the PVC pipe outside. On the contrary, using thick wires to carry small power appliances will cause a waste of resources and increase the cost of your home decoration. It's not a safety risk, but it's money well spent.

The following line standards are for your reference:

The line of entry and exit needs to choose a larger flow, and most families will use a line of 6 square meters. However, some families have installed instant water heaters, which themselves need 6 square lines, in order to ensure the safety of electricity, the household line needs to choose 10 square.

The power of the lamp is low, the average function area will not exceed 1500w, choose 2.5 square line is enough; For ordinary sockets, it is also recommended to choose 2.5 square lines, but for water heaters, air conditioners and other power outlets, you need to use 4 square lines.

There are many kitchen appliances, and the power is not small, such as microwave ovens, dishwashers, refrigerators, etc., need to be used frequently, it is recommended to use 4 square lines; The bathroom needs to use bath, water heater and other appliances, it is also recommended to use 4 square.

How soft and hard the wires are

The insulation layer is wrapped in copper core, and the wire can be divided into hard wire (BV) and soft wire (BVR) according to the type of copper core.

In the category of household wires, hard wires are mostly composed of a copper core, with high hardness and should not be bent, while soft wires are twisted with multiple copper cores, with higher softness and high price, which is suitable for more complex wiring scenes. From the point of view of the degree of oxidation, the flexible wire composed of multiple strands of copper core has more contact with the air surface, so it is also easier to oxidize, and it is certainly not as long as the service life of the hard wire.

In the category of household wires, I would recommend using a single strand of copper core hard wire, for the following reasons:

In the hydropower transformation, most of the circuit is used in the way of hidden installation, which involves the pipe, and the hard line is certainly much easier to wear than the soft line, the mechanical tensile ability is stronger, and the construction difficulty is lower. In addition, in terms of joints, the wires need to be connected by winding, winding a copper core is much easier than winding multiple strands of copper core, and the overall firmness is stronger.

In addition, the power of our common household appliances is not very large, generally about 3000W, and the small light bulb is ten watts, so the use of hard wire can meet the demand.

To sum up, the wire is not the thicker the better, the choice of the right is good, in addition, for home wiring scenarios, the use of BV hard wire is enough.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
