Found this interesting little setup positioned underneath the 69KV lines that I showed here not too long ago. They appear to be some type of switches for the lower voltage distribution lines; yet although the "switches" appear to be open, there is another conductor across the two insulators.

(Edit 7:23pm PDT 09-16-08) I received a very helpful email from somebody who viewed this photograph and knew what it was! Thank you!!! :-)

Hi Craig, That switch is actually closed. This type of switch is what is called an omni-rupter designed to break up to 600amps of current. What you are seeing that appears to be open is the arc snuffing device. Hope this helps, Ron...........
