The service life of a coaxial cable is mainly affected by the following factors:
1. Mechanical damage: a large share of cable failures are caused by mechanical damage during handling and installation.
2. Moisture ingress at joints: substandard joints or mismatched protection levels let moisture in, gradually degrading insulation strength.
3. Long-term overload heating: load current heats the conductor; excessive temperature accelerates insulation aging, with weak spots failing first in summer heat.
4. Joint workmanship: joints are the weak link of any cable run; improper crimping or insufficient heating reduces insulation quality and causes failures.
5. External environment and heat sources: external high-temperature sources can overheat the cable, break down insulation, or even start fires.
6. Natural aging of the cable body and other causes such as natural disasters.
Understanding these factors supports correct selection, proper installation, and regular maintenance — extending service life and keeping equipment running safely.
