2. The maintenance of the top of the decorated wire is much easier than that of the ground, so the top is also considered from the maintenance aspect: mainly because the moisture on the ground is heavy, so the ground is easy to break; When our buried lines are broken, we need to dig out the tiles or floors that were originally decorated during maintenance.

3. Construction cost: In terms of materials and labor, grounding may save some materials and facilitate construction; However, considering the later maintenance and other factors, the ground is not suitable for wiring.

Matters needing attention in purchasing decorative lines

1. The domestic power cord should adopt BVV2×2.5 and BVV2× 1.5 models. BVV is the national code, which is sheath line BVV2×2.5 and BVV2× 1.5, representing 2 cores 2.5 mm2 and 2 cores 1.5 mm2 respectively. Generally, BVV2×2.5 is used as the main line and trunk line, and BVV2× 1.5 is used as the single branch line and switch line.

3. Second, look at the length and price. BVV2×2.5 each roll length1005m, the market price is around 280 yuan. The length of informal products ranges from 60 meters to 80 meters. You can count the number of turns of the line and multiply it by the radius of the whole roll, and then you can roughly calculate the length. The price of such products ranges from 100 to 130 yuan. Secondly, you can ask the merchant to cut a broken head and look at the copper core material. BVV2×2.5 copper core diameter 1.784 mm, which can be measured with micrometer.

4. The regular product wire is pure copper, the outer layer is bright and slightly soft. Informal product copper is dark and hard, belonging to recycled copper, with high resistivity and poor conductivity, which will increase the temperature and be unsafe. When buying wires, you should go to professional stores such as power supply stations or factory sales departments to buy them.
