Prevention of emergency malfunctions

Abstract

The article discusses the most common type of malfunctions and the main causes of damage to the electrical cable. A case study of cable failures in the urban network shows that the main cause is the deterioration of insulation, especially due to the fact that the service life of cables reaches 35 years. Therefore, in order to prevent failures and reduce threats, it is necessary to strengthen the monitoring of cable systems and use cables with higher reliability and functionality, for instance, cables made of cross-linked polyethylene.
