Many factories that produce household appliances, power tools, computer electronic products, power adapters, or machinery and equipment must be equipped with plug power cords for their products. Therefore, power cords are ubiquitous in daily life, but what is a safe power cord, and what should be paid attention to when matching? Then we will briefly discuss it below.
First of all, to purchase power cords, you must go to a regular manufacturer and use a cord that meets the standards. my country is 3C certification, North America is UL and CSA certification, and Europe is VDE certification. Only the correct power cord can be used at ease.
Understand the power of the electrical appliance, and then match a suitable over-current power cord to prevent the power cord from being unable to withstand the power of the electrical appliance and melting and causing danger.
For some wires that are used outdoors, in damp or harsh environments, you can purchase waterproof and oil-proof plug power cords.
In addition, in order to prevent the connection from being pulled out of the plug or socket due to accidental pulling during use, the national standard stipulates that the connection point of the rewirable plug and socket must be a screw terminal, and there must be fixed parts to strengthen the tensile strength. Only the integrated non-rewirable plug or socket is allowed to be welded. Users who assemble the socket by themselves, some use twisting or knotting to connect the plug or socket to save trouble. This is not standard and unsafe. .
The length of the cable should not be too long, and try to use the power supply as close as possible; the exposed part of the plug power cable is dangerous in the passages where people are frequented. Once the cable is frequently trampled on and damaged, it is easy to cause electric shock and injury. Therefore, it is necessary to install protective wire troughs in places that are easy to be touched by people. It is also dangerous to use a too long wire in a reel. Such long-term use will cause the cord to accumulate heat and easily cause a fire accident.
