What should you pay attention to when buying wires?
Wires are essential for every household, and their risk factor is also very high, so be sure to choose good wires. So what should you pay attention to when buying wires?
1. Load capacity
The electricity consumption in the home fluctuates. When the consumption is high, the TV, air conditioner, computer, lamp, water dispenser, refrigerator, hair dryer, etc. may be used together. If the load capacity of the wire is not strong, and the weather is hot in summer, the wire will generate heat when overloaded, which may cause serious consequences such as fire.
2. Waterproof
The outer packaging of some wires is not tight and can easily deform and crack. If it ruptures and leaks, it is likely to cause electrical appliances to burn out, short circuit or even cause fires and casualties. Therefore, the wire must have a hard outer covering and good waterproof performance.
3. The main line should have a thick core
Main wires are the two main wires running from the main power supply to all electrical appliances. The main wire must use thick copper core wire, because the main wire carries the charge of each electrical appliance, and requires thick copper wire with excellent performance.
4. Length
There are many unscrupulous merchants who will fake the length of the wire. Although the wire has a meter mark, some unscrupulous merchants underestimate the length of the wire by 10 meters. For example, after 30 meters, the mark starts to be 40 meters.
2. What are the tips for buying wires?
1. Read the inspection report
As products that affect the safety of people and property, wires and cables have always been listed as the focus of government supervision and inspection. Regular manufacturers are subject to inspections by supervisory departments on a regular basis. Therefore, sellers should be able to provide inspection reports from the quality inspection department.
2. Look at the packaging
Any formal enterprise that produces products that meet national standards attaches great importance to product packaging when producing wires and cables. When purchasing, pay attention to the exquisite packaging, clear printing, and complete model specifications, factory name, and factory address.
3. What issues should be paid attention to when installing wires?
1. When installing wires, pay attention to the connection method. During the installation of wires, prevent connectors from appearing frequently. If connectors appear frequently, it will cause considerable resistance and the wires will heat up. If wire connectors appear frequently, in order to prevent the accident from happening again, the wire joints should be tightly wrapped with insulating tape.
2. When installing wires, pay attention to choosing the appropriate installation method. There are two different methods of wire installation: concealed installation and surface installation. Concealed installation refers to wires laid in places such as ceilings or walls. For safety reasons, professional personnel must be invited to operate. Surface installation refers to laying along the surface of walls and ceilings. When performing surface installation, wires cannot be folded or squeezed, and the wires must be firmly fixed.
3. When installing wires, pay attention to the correct use of ground wires. For example, when some household appliances such as refrigerators and washing machines use three-phase plugs, you must pay attention to installing a reliable ground wire.
