SANACIJA HAVARIJA NA 110 KV KABLOVSKIM VODOVIMA

This paper shows the activities and challenges that were represented by the repairs of damage to the cable lines 110kV no. 171 TS Belgrade 1 – TS Belgrade 6 and 110kV no. 172/1 TS Beograd 6 - TS Belgrade 45. The faults happened simultaneously, in August 2022, therefore simultaneous rehabilitation was not possible due to the energy conditions and power supply of the city center itself. The goal of the work is to present and point out the problems that may arise during the exploitation of cable lines, the method of monitoring the condition of oil cable lines and the repair of faults both on the joints and on the cable sheath. This paper also shows the method of washing the mineral oil with silicone oil and then adding the anagen reagent to the cable line 110kV no. 172/1 TS Beograd 6 - TS Beograd 45, installation of transition joints and replacement of part of the oil cable with paper insulation with a cable with synthetic insulation of cross-linked polyethylene on the cable line 110kV no. 172/1 TS Belgrade 6 - TS Belgrade 45, as well as the replacement of the oil joint on the cable line 110kV no. 171 TS Belgrade 1 - TS Belgrade 6.
