What are the consequences of excessive bending and stretching of indoor extension cords? How to prevent it?

Indoor extension cords are indispensable electrical accessories in modern homes and offices. They are used frequently and widely. However, many people do not pay attention to the problem of excessive bending and stretching when using extension cords. This improper use will bring a series of safety hazards and damage risks. This article will explore in detail the consequences of excessive bending and stretching of indoor extension cords, and provide some preventive measures to help you use extension cords safely and efficiently.

The internal structure of the extension cord consists of conductive metal (usually copper wire) and an insulating layer. Excessive bending and stretching will cause damage to both parts. Excessive bending can cause the conductive metal to break or break, and the insulating layer may also break or wear, exposing the metal wires. This will not only affect the conductivity of the extension cord, but also bring serious safety hazards.

When the wires inside the extension cord are damaged due to excessive bending or stretching, the exposed metal wires may contact each other, causing a short circuit. Short circuits not only damage the connected electrical equipment, but may also cause fires. In addition, the damage of the insulation layer increases the risk of electric shock to the user, especially in a humid environment, where electric shock accidents are more likely to occur.

If the wire inside the extension cord is broken or damaged, its resistance will increase significantly. This will cause the current passing through the extension cord to generate a lot of heat, which will cause overheating problems. Overheating of the extension cord will not only affect its normal operation, but may also ignite surrounding combustibles, causing fires. This risk is particularly significant when the extension cord is used for a long time and under heavy load.

Frequent excessive bending and stretching will accelerate the aging process of the extension cord and significantly shorten its service life. Frequent replacement of extension cords not only increases costs, but also increases the number of discarded electronic products, which is not conducive to environmental protection.

When using extension cords, try to avoid placing them in places where they may be squeezed, bent or stretched. Try to arrange the extension cord along the corners, behind the furniture or the edge of the floor to keep the wire in a natural bending state and avoid sharp bends and excessive stretching.

Using auxiliary tools such as wire clips and wire troughs to fix the extension cord can effectively prevent it from being over-bent or stretched. Wire clips and wire troughs not only keep the wires clean, but also reduce their damage from external forces.

Minimize the unnecessary use of extension cords. If the electrical equipment can be directly connected to the wall socket, try not to use extension cords. This not only reduces the loss of extension cords, but also reduces safety risks during use.

Excessive bending and stretching of extension cords can lead to a series of safety hazards and usage problems, including wire damage, short circuits, overheating and fire risks. In order to ensure the safety of electricity use, we should correctly wire, use extension cords of appropriate lengths, avoid heavy objects pressing on the wires, and regularly inspect and maintain them. At the same time, choosing high-quality extension cord products can also effectively reduce the occurrence of these problems. By taking these precautions, we can greatly improve the safety of extension cords, extend their service life, and ensure the safety of electricity use in homes and offices.
