The process of home improvement is also the process of building materials purchase, but many building materials are the biggest ones. For the owners of the decoration, choosing the numerous hydropower materials is the first step in the long procurement process. In the face of many materials I do not know where to start? I do not know what to choose when purchasing accessories? Please enter our circuit for you to buy Raiders, easy to get the circuit material.
â– Strong electricity
Consider the use of electrical power
The strong electricity should be selected according to the power of the appliances in the home. In general, there are six or seven strong roads at home, such as lighting lines, socket lines, high-power electronic circuits (cabinet walks alone, disinfection cabinets in the kitchen may go all the way, high-power water heaters in the toilet, etc. also go all the way) In addition, a spare line is also needed to prevent accidents.
Wires currently on the market have 1.5 mm2, 2.5 mm2, 4 mm2, 6 mm2, and 10 mm2 wires. Wang Chicun, general manager of the Hongli Boya Decoration Company, said that the 2.5 square millimeters and 4 square millimeters of wires for home life are basically sufficient.
The building materials market and the supermarket's wires are sold by meters, but they are also sold in whole rolls, such as 20 meters, 50 meters, and 100 meters. In general, the whole price is cheaper than the single purchase price. If a decoration company is chosen, the decoration company usually provides the wires and the corresponding accessories.
â– Accessories
Emphasizing quality on-demand material selection
☆Line tube: There are two kinds of materials, one is the PVC flame-retardant tube commonly used in home decoration, and the other is the galvanized iron tube commonly used in public installation. The tube is 16 mm thick and is also 20 mm thick. The thickness of the two is different, the key is to see the depth of the wall can be grooved.
☆ tube card: used to fix the line tube.
☆ junction box: junction box, socket cassette, lamp box and so on.
☆ Hose: Used for junction box and downlight plastic or metal materials.
â– Weak electricity
Choose specifications according to your life plan
Weak electricity includes telephone lines, network cables, cable television lines, audio cables, video cables, and audio cables. Although the specifications are high or low, Wang Chi-Cun said that when selecting weak electricity, it is necessary to decide whether to select high-standard products according to the owner's own life plan.
☆ TV line currently generally choose four-layer shielded coaxial cable, the most important thing is to select the TV line is to see whether the cable layer is tight, the more closely that the shielding function is better, the more clear the TV signal; also can see the thickness of copper wire The thicker the copper wire, the better its antimagnetic and anti-interference signals.
☆ audio line building materials supermarket is common 200-core and 300-core line. In general, 200 cores can meet basic needs. If the sound effects are very demanding, such as abnormal sound, etc., consider the 300-core audio cable.
☆ Network cable sales are generally super five-shielded and unshielded cable. The former is a hundred megabit speed, and even if there are multiple computers in the home, it can meet basic needs and the shielding effect is better. The latter is a Gigabit speed and has a poor shielding effect.
☆ The telephone line has two cores and four core single share telephone lines. The 2-core single share telephone line can meet the general demand, and the 4-core line can meet the needs of installing two different telephone numbers at home. In addition, there are two lines for the 4-core single share telephone line. The other lines are broken and the relative risk is relatively small. Of course, the price difference between the two is about RMB 1/m.
â– Purchase common sense
A look two-fold three check
Because many circuits are hidden projects, if there are problems or need to be modified, the project is vast and not beautiful. Therefore, it is especially important to select the appropriate circuit before making circuit modifications. In the face of all kinds of wire products on the market, how should consumers choose?
There are high and low wire specifications, but depending on the conditions of your choice, it is not as expensive as possible, but also consider longevity. For example, 4 square millimeters of sufficient wires do not need to buy 6 or 10 mm2 wires. However, if telephone lines, network cables and other products are intended to live for a long time, it can foresee changes in future life such as video telephony and other factors, and in conjunction with cost estimates, consider whether one-time placement is in place. If you only live temporarily, you can buy enough products and you don't need to purchase advanced products.
The choice of wire depends on the insulation properties. The first is to see whether the insulation is damaged, whether the thickness is uniform, whether the core is wrapped tightly, etc.; depends on the smoothness of the copper core. Secondly, you can fold the wires by one fold. The stronger the flexibility, the better. Check the inspection report, check the date and other factors. "In general, there are no problems in conformity with the national standards." It is best to purchase wire products from regular stores and supermarkets; it is better to buy brand products; and audio and television lines and other products can be used to buy audio and television products when they are purchased. It is more secure.
