How to check if wires and cables is aging?

Wires and cables products are mainly used to transmit current and provide power for various devices. Therefore, checking whether the wires are aging is an important part of ensuring power safety. Aged wires may lead to dangerous situations such as short circuits and fires, so it is necessary to regularly check the condition of the wires. Below, we will introduce in detail how to check whether the wires are aging and provide some suggestions for preventing wire aging.

一、Check the appearance of the wires and cables

First, check the appearance of the wires for any obvious signs of age.

1.The outer sheath of the wire is damaged or cracked, exposing the metal core inside.

2.The color of the wire sheath becomes darker or black, and the surface is rough and uneven.

3.There are obvious burn marks or burnt smell on the outer sheath of the wire.

二、Check the elasticity of the wires and cables

In addition to visual inspection, you can also judge whether the wire is aging by checking its elasticity. Aged wires often become hard and brittle and lose their elasticity. You can bend the wire. If the wire feels very hard and difficult to bend, or if it is difficult to return to its original shape after being bent, then the wire may have aged.

三、Check the wire connections

Wires and cables connections are also prone to aging. Check whether the wire connections are loose, oxidized, or burned. If the connection is found to be loose or oxidized, the connection should be tightened or replaced in time. If there are scorch marks at the connection, the wire there may be old and needs to be replaced.

四、Use professional instruments for testing

In order to more accurately determine whether the wires and cables are aging, professional instruments can also be used for testing. For example, an insulation resistance tester can be used to check whether the insulation performance of the wire is good. If the insulation resistance value is low, the wire may have an aging problem.

In addition to regularly checking whether the wires are aging, there are also some suggestions for preventing wire aging:

1.Avoid long-term overload operation of wires, and try to use wires and electrical equipment that meet specifications.

2.Avoid exposing the wires to harsh environments such as high temperature and humidity. If necessary, use protective measures such as insulating sleeves.

3.Clean the wires and cables regularly to avoid dust, oil and other pollutants from causing damage to the wires.

4.For frequently used electrical equipment, such as air conditioners, TVs, etc., check whether the wire connections are loose or aging regularly and deal with them in a timely manner.

In summary, checking whether wires and cables are aging is an important part of home electrical safety. By regularly checking the appearance, elasticity, and connections of wires, aging problems can be discovered in time and measures can be taken to solve them. At the same time, it is also very important to prevent wire aging to avoid safety hazards caused by wire aging.
