Polyphase short-circuiting device for LV overhead line with bare conductors – applied from the ground

.

SKU: Msp - CAA - U - nxSf/lf - Sp/lp - O/p
Category:

Application: from the ground, with a telescopic insulating stick of 9 m extended length, PTU-AS-400-6-c type (see page 11), in the following sequence of operations:

1. Using the earthing subassembly, one conductor of the line is earthed,
2. Using the short-circuiting subassemblies, the phase and null conductors are short-circuited, starting with the conductor earthed in the previous operation.

Application: by hanging the automatic self-locking clamp (CAA) on the conductor, followed by pulling down the clamp.
