I think it acts as a recloser but instead of locking out open, it will close and burn up the fuse then it will open.

Typically they are intended to prevent the fuses blowing as you mentioned and as the name suggests, some older type fuses such as the expulsion drop out fuses, in lower fault current situations can candle and not clear which creates fire hazards and other issues downstream. They can also blow out molten metal everywhere which is not ideal. The other benefit is that field crews won't need to go out and replace so many fuses which is a pain. These are great in rural fire prone areas. The only issue is supplying them. It is likely that a number are sitting on the network dead due to insufficient current supply on the line. Solar panels and batteries have been used but unsure how future proof that is. These are remotely controlled in my area so the protection / faults crew would be immediately be alerted and send a crew to investigate. Although these are technically an isolating device they can't be treated as such due to the internal clearances within the vacuum chamber being unsuitable for isolation, hence why another form of isolation is required such as the fuses or hinged blade isolators which can be visually confirmed as open.

That's just the mount point, current enters and exits through the ends.

Yeah it just sits on the wire that clamp isn't doing anything besides holding it up. They do make strip less stirrups and other types of connectors that have teeth to pierce through that type of tree wire though. For a hotline clamp.

Yeah I’m still trying to figure out what it does exactly. They mentioned it has an RC function. We have something called an ALS switch or trip saver. Maybe it’s the same function. But it sits in the switch itself in place of the fused barrel and has an RC control built in and will drop open automatically. We don’t like it much.

RobertBaratheon305 great question, I was wondering the same thing..

according to siemens' website, fuse saver can detect, open and clear a fault in as little as one-half cycle (10ms) and is configurable to either protect or replace the fuse. It can also isolate permanently faulted line segments or isolate sections for repair.

Man of Culture sounds like a fast acting circuit breaker with a fuse as the final OCD , I guess if a tree brushes the line the fuse saver trips and resets ?

I think it acts like a normal recloser but instead of locking out open, it will burn up the fuse then open.

Klein has one for skinning ends of wire but never seen one like that ...

You can get em from far west probably. It's a hot stick skinner

Ripley, they're a lot better than those adjustable ones.

It does. When making a connection to something, you brush the wire to remove oxidation. Usually the wire is bare.

@@ElectroTree01 The wire is insulated not so much for corrosion but for electrical insulation. Also helps with capacitance.

@@ElectroTree01 Eversource mostly uses Hendrix "tree" cable which is partially insulated to reduce outages from light contact with branches, limbs, etc. Otherwise ordinary jacketed cable is not insulation per se, it covers the conductor to reduce oxidation.

@@stevetalkstoomuch I realized my reply was phrased incorrectly. I agree with what you are saying.

They just skinned it
