Vertical Reach disconnects
Vertical Reach disconnects
(OP)
I am investigating the possibility of using what someone calls a 'vertical reach' disconnect in a tight spot in a 230 yard. I would appreciate it if anyone could point me to any manufacturers of such a device, and also general information regarding the physical design.
Thank you in advance.
Thank you in advance.

Switch".
I also think you mean "230 kV" for your switchyard
voltage.
You might try Siemens (Germany) at this URL:

Everything I've seen for "pantograph" (http://www.sdcem.com/Products/Sub_and_Trans/SP16506.html) seems different enough from "vertical-break" (http://www.turnerswitch.com/products/substation/tmk.html) that I think my confusion is probably understandable.
Thanks in a roundabout way to sphincterboy's post, I now have enough information to know what questions to ask for the next step. And of course I'll know now to specify *kv* so that no one thinks I'm asking about switches for my Duracell-powered 230 Volt switchyard :)

It seems the only grounded parts of the switch are those at ground level. No switch base.
Don't say amnday around here, it gets changed to arnday. (Circuit switcher dicussion)

etc. for a little higher voltage rating.

Are you satisfied. I add further infor here.
Pantograph disconnector is one type.
The other type is known as verticle break. In this one, the blade moves to 90 verticle (open) from the horizontal (closed) position from close to open position. When it is closing it reaches verticle.
ABB has, for example, complete range. You can contact them.

I think all I need now is a resource for any unusual O&M issues that might exist for pantograph devices...
