| Summary: | Technological interruptions reduce in power supply companies is
an important problem of electrical power engineering. The service
life of power cables is one of the parameters that significantly
affects the occurrence of breakdowns in cable insulation. The
article describes the thermal aging of insulating materials of
low-voltage cables and its effect on their service life. The wellknown mathematical models of insulation aging dependence
on temperature are considered. Low-voltage cables are slightly
affected by the electric field due to the large margin of electric
strength. Therefore, it is assumed that such cables are being aged
mainly due to their thermal operating conditions. Experimental
studies of cable insulation temperature monitoring have been
carried out. Seven weeks of the experiment show an insignificant
temperature change. The article also evaluates the effect of
insulation temperature on its service life. The results show a
significant reduction in service life even with a slight increase
in temperature, which shows a significant effect of thermal
destruction of the insulating material. |
