Working in the vicinity of live parts. 2011/347
Svenska Kraftnät has during the latest years been working with exchanging old shield wires. The old shield wire is Fe-lines and can have problems with damages from vibrations; these damages could result in shield wire rupture. Other damages that can be encountered are damages on clamps and brackets for example damages on axis and enlarged openings on extension links.
The 400 kV Overhead line CL4 between Laforsen and Bäsna is built in the beginning of 1960’s. In the beginning of 1990’s some restoration work was done such as control of joints, exchange of vibration dampers and spacers on phase conductor.
The overhead line between Laforsen and Bäsna has 2 existing shield wires; one of the shield wires is already exchanged to OPGW line, while the other shield wire now needs to be replaced.
There will be no possibilities for dead working during exchange of shield wire and therefore the work has to be performed as working in the vicinity of live parts.
