5663 We have hundreds. I'm glad I was at the end of the street when this one blew. Nothing like closing one and when you open your eyes, all you see is wires hanging while your ears ring.

We had those all over our 4KV system. One night after a thunder storm we were replacing fuses on a string of tubs in a rear lot line. Back then transformer poles were stepped. I got up to the fuse box, opened the door, took off the screw cap and set it on the pole step knob. I replaced the fuse, and reached up and closed the door. Dang if I forgot the cap, there it was on the step, and I had picked up load, but the connection was loose because the cap is the contact point. Lights blinking, arcing inside the box. . . .I had to pull the door back open, there was an arc, not as big as I expected, but enough, I never forgot that cap again.
Way back, they used to hang those boxes on the cross arm with a hanger. There was a hole in the hanger, so you could nail it to the arm, but a lot of them were just hanging there. So closing those boxes were hard to do with a stick, because you could lift the hook and fuse box off the arm trying to close with a switch stick and then you had problems.

Not too much 4 kv left in these parts. We have it and a neighboring town has it. We're the last of the municipal utilities. They've gotten rid of most of their porcelain boxes, I wish we were more aggressive about it. If I get a blown fuse and I have time, I try to throw a polymer in with a new arrestor.

When they used those boxes on riser fuses, in order to open and get a clearance with grounds, we had to pull the leads out of the bottom of the box. We didn't want ground stress across the porcelain. Just another reason to eliminate them. Not sure there are any left out there in our system.

We do work for a small Muni near us that does not have any lineman working for them. Since it is somebody elses system we can't do a wholesale change out BUT my standing instructions are if there is any excuse change it out on a trouble call to a standard cutout. We have changed over fifty still a couple of hundred to go.

We still have tons of them. They fall off the pole on their own on nice sunny days all the time. I had one that fell in front of the entrance to a bank on a Friday around noon time. I don't know how it didn't hit anybody. I had another one fall of the pole on a perfectly fine day and a guy walking got hit with the shrapnel. He didn't want to report anything. One day one of these is going to fall on somebody's head and kill them. They wouldn't let me take an outage on the main line to open the other two that were cracked so I left them up there. I've probably had at least ten times where these fell off the pole in a high foot traffic area.

The only good thing about them is they usually break on the bottom leaving the live tap intact... Usually.

That's really Amazing. I personally think the things should be done away with...completely.

It's incredible that there is not a Polymer cutout made for 4 KV that could replace these dman things.

I was replacing fuses in those things back in 1969!! Who ever makes them...must have connections to stay in business!!

Seriously....think about it....It would sure seem that making a Polymer cutout for 4 KV....would be a hell of a lot cheaper than makin those "Glass" things.

Unbelievable.

We don't put new ones up, but there are still a lot left and no plans on changing them out unless they break. I guess they figure they will change them all when all the 4kv circuits get converted which means they will probably be up there for another 30 years. They could have a bunch of workers get hurt by them and blame it on the worker for not noticing cracks. One civilian getting hurt and you will never see them again on our territory.

Have them left over from conversion to 7200 and still working.

Lots of them left in my part of the world on the old 4kv system, but I have to admit, I don't usually have much trouble with them. If I do they get changed. We still have the old " chocolate boxes" and the newer sky gray ones. By the way do any of you fellas still have to deal with the old enclosed solid blade switches?

last few I had, the primary on top was cooked back about 4 inches. I've been doing line clearance for a bout a week now, I'd welcome a blown cutout right about now. Tomorrow I have to rewire a meter on a CT cabinet that a contractor goobered up. Small muni, I'm the lineman, the trouble man, the tree guy, the street light guy, the metering guy and the substation guy.

The ones I encounter are chocolate covered. And half of those are boken by the l bracket and hanging by the jumper. Pulled one and it fell apart.
