Research on Countermeasures for 35 kV and Below Cable Lines Fault Based on Preventive Maintenance
This study aims to explore preventive maintenance based solutions for faults in 35 kV and below cable lines,in order to improve the reliability and service life of cable systems. The research content includes analyzing the causes of cable faults,testing on the insulation performance of cables under different environmental conditions,and developing reasonable laying plans and accessory selection specifications. Through detailed analysis of the causes of faults such as mechanical damage,insulation moisture,and insulation aging,and verification of experimental data,the main causes of cable faults and their prevention and control measures have been clarified. The research results indicate that preventive maintenance strategies significantly improve the stability of cable systems.
