Project name

Dismantling of Electric Power Supply Systems

project status

Completed

Description

Objectives: dismantling of of unnecessary electric power supply systems and the optimization of the electric scheme
The buildings and installations to be dismantled and demolished are:
• Transformer foundations, including oil tanks (CB 510:V1),  backup transformer stand (CB 510/1:V1 in old technical design documentation) and approach transport railways
• Two electrical transformers (T1R and T2R) and the disposal of the resulting waste material after the dismantling and scraping of both transformers. The design for the demolition of the civil part of the structures will also include tag out (BIDSF project A7.1 Tag out), disconnection, dismantling of the cables of the demolishing structures and in CB 350:V1 till determined boundary, dismantling of cable routes and trenches in CB 510:V1, 522:V1 and electrical equipment. The cabling of the demolished CB‘s will have to be disconnected on both sides (on the side of the electrical equipment in the building and on the side of electric equipment in the other CB‘s connected to the demolished CB with cables).
• External Switchyard Station 220 kV- 1. unit area and 2. unit area. (CB 522:V1),
• House of relay protection 220 kV, 110 kV (CB 523a:V1),
• Compressor plant for the 220 kV switchyard, including oil bulk tank (CB 523b:V1),
• V1 NPP Garage next to compressor plant switchyard r220 kV (CB 523c:V1),
• Garages (CB 523d:V1),
• Security fencing of the switchyard (CB 526:V1).

The project will also include partial dismantling of:
• Lines and channels of power supply cables (CB 350:V1) and lines and channels for ground connection (353:V1)
• Fire water distribution for transformers (CB 372:V1) – 5. Phase
• Removal will focus on the distribution of overhead including lodges above stacks. Pipes under the road are not subject to removal.
