Combined disconnectors

[arango]

Hello,

The picture attached to this message shows a disconnector that combines a semi-pantograph disconnector and a knee-type disconnector, I’ve been searching through the web to find any manufacturer with this equipment among its products list, but so far my search has not been succesful. I would like to know if anyone could give some guidance about this equipment (manufacturer or any useful data), a client wants to see if it can be incorporated in some of its new designs, but I don't think that this disconnector is normally manufactured, it looks to me that it corresponds more to a special request to a particular supplier, rather than a normal supply from any manufacturer.

Thanks,

My question is, why do you need this? Chances are its not a common make for a good reason.

Assuming you need only a standard photographer this is what I would choose:

If I am correct this company is used for pentographs all over Italy and Europe with excellent reliability.

Thank you all for your responses but I think I was not entirely clear. What I'm looking for is a manufacturer that provides a disconnector with the functions of a pantograph and a knee-type all togetherin one equipment.

This equipment is used to put in service the spare unit of an inductive bank of 4 units(national regulations requires a spare unit for each inductive bank). During normal operation, the pantograph is open and the knee type is closed, connecting each one of the 3 inductive units that conform the bank with the system. Once an inductive unit fails, the knee type part of the equipment opens disconnecting the failed unit, and then the pantograph part closes (above the pantograph is a flexible conductor wich is connected to a spare unit), int that way you can take out the failed unit and replace it for the spare unit in a very short time, without the need of changing any high voltage connections in the switchyard or moving the spare unit to the place where the failed unit is.


I appreciate any help with this issue.
