Summary
DescriptionStrain-insulators 66 230 115 kv.jpg |
English: Exhibition of high voltage strain insulators at the Manitoba Electrical Museum, 2003. From the left these are used for 66 kV, 230 kV and 115 kV lines. Different areas require different numbers of insulator disks for the same voltage if there is more contamination, for example, near the sea. Photo taken July 7, 2003; cropped to remove irrelevant background. |
