There are many home appliances and 3C supplies in modern houses. With the large demand for electricity, extension cords have become a must. However, the extension cord is not a once-and-for-all product, and it may be deteriorated or damaged.recentlyJapanmedia“A New Day”referring to the data of the Japanese Wiring System Trade Union, pointed out that the life of the extension cord is only about “5 years”, and shared the characteristics of the extension cord’s deterioration and better usage methods.
4 major characteristics of extension cord deterioration:
1. The whole extension cord or socket is overheated
If the socket is plugged and unplugged too frequently, or if it has been pulled out with brute force, it may cause poor contact and increase the temperature of the extension cord base.
2. The electrical appliances connected to the extension line stop suddenly
Sometimes when an electrical appliance is plugged into an extension cord, there is power for a while, and then it suddenly goes out, which may be a sign that the internal circuit has been damaged, and you need to be careful of short circuit and fire.
3. The socket is obviously too loose
When you find that the plug is still too loose after being inserted, it means that there is something wrong with the fixing device inside, and it is a sign that it needs to be replaced as soon as possible.
4. The extension cord plug is burnt, melted or bent unnaturally
If you plug and unplug the extension cord socket too roughly, it will also damage the plug itself.
If you want to extend the life of the cable, you can refer to the following points:
1. Do not pull the extension cord too much.
2. Do not place heavy objects on the extension cord.
3. Keep away from water and moisture.
4. Do not bundle the wires together to avoid danger from overheating.
