Yeah they could just dig a hole around the pole where the existing wire enters and then cut the old conduit and connect the new conduit to the remaining stub of old conduit. Afterall, they have to dig to do it this way too and by doing what I suggested, it saved from drilling a hole and having an exposed conduit. Looks better when everything is concealed.
Ahh our freeway lighting has manholes next to each pole where the splices for the pole are made. I think there's also a fuse or breaker in there too. The hand holes in the pole are not used by RIDOT or NGrid for freeway poles. So if there's a wiring issue, they just replace the cable running from the manhole to the top of the pole and whatever else is wrong. No exterior conduit.
Our lights downtown are wired up like that but I believe poles in suburban areas and freeways have the conduit going straight to the handhole where the splices are made.
The older freeway poles have short transformer bases with handholes but I don't think they were ever used for splices.
Ahh, MTO used poles with short transformer bases like this on their late 60s-early 80s steel poles. They then switched to breakway couplings in the mid 80s.
Around the 80s they also experimented with direct bury aluminium poles. Those had a breakaway section near the base of the pole. The direct bury late 60s-70s concrete truss poles were non breakaway as they were always installed behind a guardrail. For exposed poles, a steel pole with a transformer base was used. Interestingly they had a slightly different truss arm. It was steeper than the truss arms used on the concrete and later steel poles.
This is pretty much the only install here with the full size transformer bases. I'm pretty sure the poles used to have MV clamshells too. Even the double guy poles in the area have a rounded section at the top where a pole mounted ballast would have been.
Those direct bury poles with the 250w M-250R2s look almost exactly like a Ontario setup. Even the arms look similar lol.
Over here almost all poles on arterial and residential streets are non breakaway. The most common types of poles are either direct bury concrete or steel/aluminium poles bolted directly to the base. Interestingly even some poles on freeways poles are also bolted directly to the base.
Country roads seem to have poles with breakway couplings though.
I think the breakaway bases are probably required over a certain speed or something. Wow those double-guys are cool! They look like the poles seen a lot in Florida, with the square concrete shape.
WAAAIT... Where did my comment go?
BTW, did you ever get my email response a while back? It's been a while since we've emailed. I want to make sure my response didn't get lost before it reached you.
That's really weird. I don't know what happened to your comment either. There also dosen't seem to be a option to restore your comment from the site itself too.
Yeah, the square concrete poles are pretty neat. They were pretty common back in the 50s and 60s but I think the round poles killed them off.
Yeah I did, I just sorta forgot about the email. I'll send you a reply soon.
Hmm weird. I didn't delete it. I got confused for a minute since you referenced a link I made and I'm like "wait, Where's the link i made?" lol.
Oh that's fine. Whenever you get the chance. Working full-time I don't have a ton of time for emails but I wanted to make sure I had replied. Didn't want you to think I was blowing you off or something.
Ahh, my apologies if I made it seem like I was blowing you off too. I guess I'm the same once school starts and my lighting finds dwindle down. Granted I didn't really find that much new lighting stuff this summer aside from the preheater lol.
