Section insulator from the "big" railways in Melbourne.
Where they have space they run in a new wire and don't bridge across.

It's 'feature' appears to be easily replaceable segments and the 'arc chute' to pull the arc upwards and extinguish it.

I notice that the two bits were the arc would form are separate segments , joined with short link wires.

In the event a section needs to be isolated for works, the link wires would be disconnected by the crew setting up the exclusion zone making a large dead gap that the shoe wouldn't be able to bridge.
