1.5 mm2 conductor is suitable for places with low electric power such as lighting lamps;
There are circuit branches in the switch socket, which is suitable for using 2.5 square mm conductor;
High-power electrical appliances such as air conditioners and refrigerators. The main power of the circuit is relatively large, and it is best to use wires of more than 4 square millimeters;
Lines with large carrying capacity, such as trunk lines or central air-conditioning lines, are generally too thin to bear, so it is best to use wires with a diameter of more than 6 square millimeters.
1. Look at the brand: brand ranking and value are the cornerstones of product quality and safety. Choosing regular well-known brands can largely avoid buying inferior products. For example, the Far East, as one of the top 500 Asian brands and top 500 Chinese enterprises, has a brand value of 98.610.6 billion, and won the "National Quality Award" for 38 consecutive years, with a guaranteed reputation.
2. Look at the product:
Packing: The tray is neatly packed and the items on the certificate are complete, including but not limited to trademark, factory name, address, telephone number, specification, plate, inspector, etc.
Inner core: copper core is selected for longer and safer service life. Pure copper core is the best, and the color is purple; In addition, it depends on whether the inner core is in the middle of the insulation package. Inferior wire rod has a large degree of eccentric core problem. The eccentricity is high, and the thin part is easy to be broken down, which has the risk of short circuit and fire;
Logo: The wires should be printed with relevant logos, such as product model and company name. The printing is clear and evenly spaced;
Smoke: burn the wires with a lighter. Ordinary wires will release toxic gases when they encounter open flames, further increasing the risk of short circuit fire. Flame-retardant wires will cut off when exposed to open flames, and will not produce toxic gases. Therefore, it is recommended that you install and use low-smoke halogen-free flame retardant wires, which is safer and more environmentally friendly;
Weight: the length of the national standard line, the general number of packages is marked as 100m, and the actual measurement is also full of meters of copper, which has a certain weight.
Generally, the property right of residential houses is 70 years, and the Far East "wire with good core and thick edges, high safety and environmental protection" can be used for 70 years, truly wiring once, and worry-free for life. Appearance, the Far East "Good Series" wires are beautifully packaged and the product certificate information is complete; The raw material of the inner core is 99.99% pure copper core, which has the advantages of low resistivity, strong conductivity, energy saving, low eccentricity, high concentricity, breakdown prevention and safer electricity use. The insulation layer is made of high-quality environmental protection PVC material, which is more wear-resistant, corrosion-resistant and aging-resistant. At the same time, flame retardant is added, which has the characteristics of high performance, low smoke, no halogen and no toxicity. The length of the national standard line is marked as100m, and the actual length is 95-100m. In this regard, the Far East can guarantee the length of 100 meters, which is superior to the national standard.
3. Look at the strength, whether these materials are used in the familiar building decoration, choosing the Far East and the Hong Kong-Zhuhai-Macao Bridge, China Zun and so on are all the same choices.
4. In terms of after-sales, an important factor that distinguishes big brand wires from miscellaneous brands in the market is that there is a genuine guarantee that can be traced back to the whole process, which can effectively prevent consumers from buying counterfeit wires. Far East Wire has double after-sales guarantee, not only Pacific insurance guarantee, but also no reason to return it within 30 days. There is also two-dimensional code anti-counterfeiting protection on the packaging of each winding, which can be traced all the time, so you can rest assured.
