Aging or other faults may occur during the use of cables. What causes the aging and failure of cables? Here's a simple analysis.
Reasons for cable aging:
1, insulation damp
For some aluminum cable itself may have some quality problems, in the humid environment will easily lead to cable insulation damp, thus causing failure.
2. Chemical corrosion
If the aluminum alloy cable is buried in the area with acid and alkali effect, the armor, lead skin or outer protective layer of the cable will be corroded. The protective layer will suffer from chemical corrosion or electrolytic corrosion for a long time, which will lead to the failure of the aluminum alloy cable.
3. Long-term overload
Cable in the use of the process, long-term high load work will also lead to cable damage, so it may lead to the occurrence of cable fault.
4. Joint failure
Cable connector is the weak link in the cable line, when the cable connector may cause cable fault, so the construction personnel should be very careful when carrying out the cable connector.
The causes of cable failure and aging mainly include the above several factors. In practical applications, people should timely check the wall hanging to solve such problems.
