What are the causes of the aging of wires and cables? (2)

2. Environment and temperature the external environment and heat source of the cable can also cause high temperature, insulation breakdown and even explosion and fire.

3. Damp insulation is also very common, which usually occurs at the cable gland directly buried or in the pipe. For example, if the cable gland is not made up to standard or is made under humid climate conditions, water will enter into the gland or mix with water vapor. After a long time, R will form water tree under the action of electric field, which will gradually damage the insulation strength of the cable and cause fault.
