because the trees were snapping under the weight of the ice, and the falling branches were making contact with the lines, or breaking them. This new wire has an insulating layer around it so that if a tree has brushing contact with it, it won’t cause an outage or a temporary blip. We’re also doing trials with breakaway links. During the ice storm, when the service wire was brought down by the trees, that service wire also brought down the customer’s mast and his/her meter at the base, and only once those repairs have been done can we come in and reconnect. The breakaway link is almost like a mechanical fuse. If the weight of the tree brings down the line, it snaps this mechanical connector, which interrupts power and makes the service wire fall in a controlled way. It’s also de-energized, so we don’t have to worry about a public safety issue.”
