Unknown device in HV transmission installation

(1/3) > >>

eblc1388:
The picture is taken from a HV outdoor installation somewhere in China. What is the name and purpose of the circled device mounted under the corona shield on top of the bushing?


bob91343:
Maybe just a warning siren, unrelated to the high frequency stuff.

NiHaoMike:
Might it be a microwave horn for some sort of wireless sensor?

f4eru:
could it be an E-line launcher, with the outgoing wire not yet mounted ?

Love High Voltage  :scared:
 

AlbertL:
It appears to be directly connected to the high-voltage line, so I don't think it would be anything like an antenna or sensor that would require power or signal wiring.  My guess is that it's a contact or receptacle for a jumper cable or disconnect/isolating switch.
