When undergoing water and electricity decoration, people are generally reluctant to go to the site to check. However, they do not know that the water and electricity decoration is the most important part of the entire decoration. The decoration of water and electricity is related to our future life and even the safety of our family! Many people don't know much about water and electricity, and the knowledge about water and electricity is relatively professional. Is the wire better to be multi-stranded or single-stranded? It cost me 50,000 yuan to rework my home!
1. Is it a single strand or multiple strands?
1. Construction: multi-strand wires are easy to construct
Because the single strand wire is made of a thick copper wire It is made of wires that are a bit harder than those with multiple strands, so it is relatively difficult to thread during construction; while wires with multiple strands are much easier to thread.
2. In terms of heat dissipation: multi-stranded wires have certain advantages in heat dissipation
Multi-stranded wires are composed of multiple thin copper wires, and there is a certain gap between the copper wires. , so it has certain advantages in heat dissipation.
3. Is it easy to oxidize: single-stranded wires are not easy to oxidize
We can check the multi-stranded wires that have been used for a long time. Some of the thin copper wires in many multi-stranded wires have been It is oxidized and disconnected, so that the cross-sectional area of ??the wire is reduced, which increases the safety hazard of electricity; for single-strand wires, only the surface part will be oxidized, but the middle part will not be oxidized. , more durable.
4. In terms of price: single-strand wire is relatively cheap
Multi-strand wire is composed of multiple thin copper wires. During production and processing, the process is slightly more complicated, so The cost will also be a little higher; while single-strand wires are relatively cheaper.
Through the above analysis, in terms of use, single-strand wire has certain advantages, while in terms of installation convenience, multi-strand wire has the advantage. Therefore, for owners, it is recommended that you choose single-strand wires. From the perspective of installation masters, more masters are willing to choose multi-strand wires.
2. How to choose wires
1. Look at the logo
Wires are CCC products with compulsory certification by the country. When purchasing, you must choose those with the 3C logo. electric wire. At the same time, pay attention to whether the product name, factory name, trademark, specifications and models on the wires and the certificate are clear, standardized and accurate.
2. Look at the insulation layer
High-quality wires are bright in color, the wire body is shiny, the insulation layer is soft and tough, has good stretchability, and the surface looks tight and smooth without roughness. , the outer sheath of high-quality wires is thin, the outer sheath and the copper core are tightly wrapped, and the outer sheath basically cannot be easily rotated.
3. Look at the copper core
High-quality wire core has a metallic luster, bright surface, smooth, burr-free, high twisting tightness, softness and toughness, and is not easy to break. The color of copper wire has a particularly bright metallic luster.
4. Look at the diameter
Generally speaking, the thicker the diameter of the copper core, the higher the price and the better the quality. As for what specifications of wires to buy during decoration, it should be determined according to the specific household appliances. You can consult the decoration company or electrician before purchasing.
5. Color differences
Wires for different purposes should use different colors: For the convenience of maintenance, wires for different purposes should be of different colors. Use red for the live wire, blue and green for the neutral wire, and yellow and green for the ground wire. No matter which color you choose, the same color should be consistent.
6. It’s better to have less, not more
If you buy less, you can replenish it, but if you buy too much, it will be wasted. Household wires are divided according to cross-sectional area, and there are three main specifications: 1.5mm is generally used for lamps and switch wires. This wire is also generally used for ground wires in circuits. It has more two-color wires, which can easily distinguish colors. 2.5mm is generally used for sockets and some branch lines; 4mm is used for circuit main lines and special lines for air conditioners, electric water heaters, etc. In addition, there are no 6mm copper core wires, which are rarely used in home decoration.
7. Look at the manufacturing process
Cut a section of the insulation layer to see if the core is located in the center of the insulation layer. What is not centered is the eccentric phenomenon caused by low craftsmanship. If the power is small during use, it will be fine. Once the power consumption is large, the thinner side is likely to be broken down by current. For on-site testing, you can take a piece of wire and bend it repeatedly by hand. Any wire that feels soft, has good fatigue resistance, has high plastic or rubber feel and has no cracks on the wire insulation is a high-quality product.
The outer plastic skin of the wire should be bright in color and fine in texture, and there should be no open flame when lit with a lighter.
When we choose whether the wires should be multi-stranded or single-stranded during home decoration, we must inquire clearly in advance and consider practical issues. Don't be like the editor who was careless and ended up reworking in order to save money. Water and electricity are responsible for the normal life of our homes. If there are problems with water and electricity, it will affect our lives. Moreover, water and electricity are hidden projects, and it will be quite troublesome to rework!
