电线和电缆的日常维护和保养需要做些什么？

In people's daily lives, few may notice issues with electrical wires. Nowadays, many households use concealed wiring, making the wires largely invisible and unnoticeable, including whether they are aging or damaged. Electrical wires are consumables, and failing to maintain them can significantly shorten their service life. But how should we maintain them? Below, I will share some knowledge about electrical wire maintenance with you!

It is very dangerous when electrical wires lose their insulating properties, which is also known as insulation aging. If two wires touch each other or a live wire touches something connected to the ground, electricity leakage will occur, causing the temperature of the local wires to rise, producing sparks, and potentially leading to fires. Therefore, please pay attention to the following:

Additionally, when maintaining electrical wires, special attention should be paid. Do not directly wipe live wires with a wet cloth or spray cleaner on them. Instead, unplug the power source and gently wipe them with a soft cloth dampened and squeezed dry. Regardless of whether you are organizing or cleaning any electrical wires, always turn off the power first to avoid electric leakage or electric shock accidents. Besides the above points, we should also pay attention to:

The service life of electrical wires depends not only on their quality but also on the installation environment. The insulating layer is a crucial component that controls the lifespan of electrical wires. If they are exposed to a humid environment for a long time, the insulating layer will be corroded, gradually reducing its insulating properties and causing the wires to age, crack, or fall off. This phenomenon can easily lead to fire accidents and cause casualties. Therefore, when installing household electrical wires, avoid areas with moisture and direct sunlight to extend their service life.

Now that you understand the installation environment of electrical wires, you should also pay more attention during daily use. With the continuous improvement of socio-economic levels, household appliances such as dishwashers, robotic vacuum cleaners, and humidifiers have gradually increased, causing household wiring to frequently operate under overload conditions. Overload usage can cause the local temperature of the electrical wires to rise, thereby accelerating the aging of the insulating layer, shortening the service life of the wires, and causing short circuits that may lead to fire accidents. When using electricity daily, try to avoid using high-power appliances simultaneously. Additionally, during special weather conditions like rainy days, close the windows and doors, avoid using appliances as much as possible, cut off the power supply, and perform daily maintenance on the electrical wires.

To ensure household electrical safety, everyone should regularly conduct safety inspections of household wiring and electrical equipment. At least once a year, invite professionals to conduct a comprehensive inspection, especially for wires that have been in use for a long time, to check for aging, damage, and other issues, and promptly repair or replace them to prevent the risk of electric shock and leakage, ensuring the normal operation of household wiring and extending the service life of the wires.
