For modern people, electricity has almost become as common as breathing air, but many people think that circuit knowledge is too esoteric and there is no need to understand too much. In fact, as long as you spend a little time understanding the general household electricity knowledge, you can safeguard the safety of daily life and take preventive measures. We are in this attitude and sentiment, and we will send you related knowledge about electricity use.
In 2016, home structure fires caused 81% of the civilian fire deaths and 73% of the civilian fire injuries. (Homes include one- and two-family homes, apartments, town houses, row houses, and manufactured homes.)The graph below shows how the leading causes vary depending on whether the interest is in fires, deaths, or injuries.
Heating equipment was involved in one of every five home fire deaths. Heating equipment ranked second in reported home fires and home fire injuries.Electrical distribution or lighting equipment was the third leading cause of home fires. This category includes fixed wiring, meters, switches, receptacles, outlets, cords and plugs, and lighting equipment. Electrical distribution or lighting equipment was involved in 9% of home fires, 10% of fire injuries, and 18% of home fire deaths. Electrical factors can play a role in any fire involving equipment powered by electricity. Electrical failures were factors in 13% of home fires. This data is from nfpa.org, I believe extension cord are familiar to all of you, and you’ve heard load of ways to choose a power strip. Let me share three tricks for choosing it.
Heavy is good. Weight can be a good indicator of extension cord, maybe you thought you were reading a fresh produce article, I am serious, well, let’s go on. The extension cord is mainly composed of the external casing, internal conductive wire, and power cord. Materials used to make a high quality power distribution is often excellent in fire resistance, while on the contrary, if some materials from old plastic, months after using it, of which will begin to chalk and crack, not to mention the capability in fire resistance. If the internal conductive wire is made of PC board copper foil or a relatively thin copper material, it is easier to generate heat in high-current loads like using ovens, electric pots, or water heaters.
In addition, the thickness of the power cord is also very important. We produce strictly according to the standard value 2.08mm2 of UL conductor specifications, one more notes, although there are standard values for the conductor specifications are the same, 0.208mm2*10 and 0.0208mm2*100 for example, the multiplied result is the same, while the wire diameter used in the former one is larger than the latter, that is to say, in terms of a single wire, in the performance of conductive capability and heat dissipation the former one is better. The easiest way is to bend the power cord by yourself, the more easily to bend, the weaker in heat dissipation performance. In the summer high temperature environment and using with high-current loads is more prone to danger, while the sturdy lines provide good heat dissipation conditions, which greatly reduces the danger.
Then try to plug some appliances into the port. Many extension cords are often use only one-sided contact in order to lower the cost, normally the contact surface is small and loose itself, which make it easy to plug in and the spark generate and electrical conductivity is cut down by carbon that generated by spark, together with a long-term of high power and current, the socket will be getting heat.
Next, look over the outer casing. As an important part of the insulation and protection, the fire resistance capability cannot be overlooked. eLIFEconnection provide V0 grade flame-proof material, the thickness is up to 3.5mm have a higher level of safety when compared to the thickness [0.7mm/1.5mm/3mm] required by UL test standards. Glossy PC panel surface adopts advanced HB grade mirror production technology. It is scratch-resistant and not cracked, showing your taste.
Finally, you need to check whether the connection between the wire and the plug is firm enough. Many extension cords in the market are welded with wires, which are easy to loose and burn heat. This little detail cannot be ignored either.
