Snow Removal Unit SRU
The SRU utilizes the weight of the snow itself to clear the power lines. When reaching a pre-set threshold, the SRU gives the line a sudden impact, making the snow fall off. Afterwards, the SRU resets itself and is ready to repeat the process again – and again.
Currently mounted in Norwegian and swedish 22 KV and 66 KV linesConstruction Purely mechanical. No electricity or external power required.Current pulldown weight on lines Lowest 40 kgs
Highest 150 kgsClips Currently: 16mm and 20mmConstruction max load 70 KNMounting The SRU is mounted in the same way as an insulator.Time of year, mounting All year. Summer is best :-)Ice The SRU does not target ice, but removes snow before it turns into ice.Line position First version was for lines running below the cross arms. Raised above is currently piloting.Effect The release removes snow in both directions from the pole. 1 unit per line is recommended, but releases removing snow from parallel lines has been observed.
