25kV Range – High Voltage Couplers

25kV RANGE – 25,000 Volts, 800Amps, IP68, open cut coupler

The 25kV range.

AusProof were the first in the world to design and develop the 22,000 volt range stretching the limits of current understanding and knowledge of high voltage. So, we do it again with 25kV coupler.

Featuring major break throughs in design and materials, this is the safest 25,000 coupler on the market.

With full phase to earth segregation, this product has been in service since 1990
