Wow!That is very interesting, it's amazing that a pole can even survive almost 100 years of frost/defrost like that and still hold any lines. I guess considering the incredible distances involved here in Canada, keeping track of the poles and actually inspecting them is a huge challenge though. I wouldn't have thought broadband added any significant weight on the poles though!
And you are right, that storm was pretty unique because of how much ice (instead of snow) it ended up creating. But honestly, it wouldn't surprise me if we see another big grid failure soon. The network has been noticeably less reliable the past 2-3 years, and not just in my location. I've had to build a DIY UPS for my home server this year because of that (the outages have been around 7-8h each so an off the shelf UPS was not really an option if I wanted 100% uptime). Hopefully I'm wrong because electric heating is massive here.
- bcrl 5y agoThe biggest risk when adding new fibre to existing pole lines is actually during the installation process. When new cables are lashed to communications strand, the 45 pound cable lasher causes the strand to swing back and forth quite significantly, making the tops of nearby poles swing several feet or more. As a result, insulators that are old and of certain types that may develop cracks can break off during lashing. Direct or even indirect contact with a 7.2kV or 16.8kV primary by communications workers can be deadly, and is a real risk of this kind of work.
