SF6 handling Monitor for extra high Voltages

SF6 handling Monitor for extra high Voltages

SF6 leak testing units – from small to extra large Model range "LeakScanner SV" Vacuum testing of smaller components (without gas handling) This model range with a chamber volume of approx. 50 - 500 l is the ideal solution for testing smaller components where gas handling can take place outside the test chamber.

    SF6 circuit breakers suffer less wear on the main contacts than do air and oil circuit breakers. The breaking principle is to cool down the arc by blowing SF6 gas with high pressure towards the arcing contacts. An SF6 circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.
