Cable aging is a slow cumulative process caused by the combined action of multiple factors, which eventually manifests as the decline of insulation performance, and even leads to accidents such as short circuits and fires. Understanding these causes helps us better prevent and replace aged cables in time.

There are a wide variety of cables with diverse classification methods. From the most commonly used dimensions, cables can be classified by voltage level, insulating material, conductor material and application purpose, which are introduced one by one below.

The use of wires and cables seems simple, but in practice, many users are prone to fall into several common misunderstandings due to lack of professional knowledge, which not only affects electricity safety, but may also lay hidden fire hazards.

Electrical cable installation is a key link in electrical engineering, and the installation quality is directly related to electricity safety and system stability. The following are the core precautions that must be strictly followed during the installation process.

As the "blood vessels" and "nerves" for electric energy transmission and signal transmission, electrical cables are applied in almost all industries of modern society. The following are several core application fields:
