What factors affect the service life of indoor extension cords?

Indoor extension cord play an important role in our daily lives, but their service life is affected by many factors. Understanding these factors can help us better protect extension cords and extend their lifespan, thereby ensuring the safety of our homes. Here are some factors that affect the lifespan of indoor extension cords:

Material quality: The material of the indoor extension cord directly affects its service life. High-quality plastic or rubber materials can better withstand the friction and pressure of daily use and are more durable. Choosing an extension cord made of high-quality materials can extend its lifespan.

Frequent use: Indoor extension cords are often used to connect various electrical appliances and equipment. Frequent use will lead to core aging, insulation damage and other problems, thus affecting the service life of the extension cord.

Overload use: Connecting electrical appliances whose power exceeds the rated power capacity of the extension cord will cause overloading, which will accelerate wire core aging, insulation damage and other problems over the long term, and reduce the service life of the extension cord. 

Environmental factors: Exposure of indoor extension cords to different environments, such as high temperature and humidity, will accelerate their aging and damage, thus reducing their service life. Try to keep extension cords away from high temperatures and moisture to extend their service life.

Pulling and bending: Improper use, such as excessive pulling or bending of the extension cord, can cause problems such as wire core breakage, insulation damage, etc., and reduce the service life of the extension cord. Correct use and placement of extension cords, avoiding excessive pulling and bending, can extend their lifespan.

External damage: Indoor extension cords are susceptible to external damage, such as cuts, cracks, etc., which can lead to problems such as exposed cores and damaged insulation, reducing the service life of the extension cord. Taking care to avoid external damage can extend the life of the extension cord.

Regular maintenance: Regular inspection and maintenance of indoor extension cords to detect and repair problems in time can extend their service life. Regularly checking plugs, sockets, cores and other parts to ensure they are working properly can reduce damage caused by undiscovered problems and extend the service life of extension cords.

Operating ambient temperature: High temperatures will accelerate the aging of plastic or rubber materials, leading to problems such as damage to the insulation of the extension cord and softening of the core, reducing its service life. Try to place the extension cord in a room temperature environment to extend its service life.

Keep dry: A humid environment will cause the extension cord insulation to become damp, accelerating aging and insulation damage and reducing its service life. Try to place the extension cord in a dry environment to extend its service life.

Quality selection: Finally, choosing a high-quality indoor extension cord is also a key factor affecting its service life. High-quality extension cords typically feature high-quality materials and craftsmanship, making them more durable and last longer.
