home decoration is inseparable from wires, and the purchase of wires is particularly important in the decoration process. When choosing wires, we should first use copper core wires that meet the standards. Insulating materials should be reliable and resistant to aging damage. The specific standard should be bvv2× 2.5 and bvv2× 1.5 type of wire. BVV is the national standard code, which is copper sheathed wire, 2× 2.5 and 2× 1.5 represents 2-core 2.5 mm2 and 2-core 1.5 mm2 respectively. Generally, 2× 2.5 main line and trunk line, 2× 1.5 make a single electrical branch line and switch line. Bvv2× for single-phase air conditioning dedicated line; 4. Special ground wire is additionally provided

brand store: Panda wire

but there is a difference between theory and reality. Now fake goods are made more real than real goods. Therefore, combined with the decoration experience of experts, talk about the three ways to buy Wires in reality

first trick, purchase method

in big cities, it's actually easy to buy authentic products. Just call the factory directly to buy them. Beijing directly calls Kunlun factory, and the line of 25 is 168 yuan (the national standard line of big factories is full-scale). Pandas can be selected from Shanghai, and there are places to order online

it is much more troublesome for those in small cities. Before buying, you can call the factory and ask whether there is an agent in this city and whether there is delivery. If not, try not to choose these brands of wires. Most of the wires bought outside are fake. When buying wires from unknown manufacturers, try to choose products from big city wire factories. It's best to buy them from agents, which are cheap and reliable
