Sulfur hexafluoride circuit breaker - Wikipedia

The first high-voltage SF 6 circuit breaker with a high short-circuit current capability was produced by Westinghouse in 1959. This circuit breaker in a grounded tank (called a dead tank), could interrupt 41.8 kA under 138 kV (10,000 MV·A) and 37.6 kA under 230 kV (15,000 MV·A).Get price

Digital radiography for inspection of gaz sf6 | TD Guardian

This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class gaz sf6 dead tank breaker, two to three exposures per phase are required to provide adequate data. For this breaker size, Siemens can typically complete inspections on one to two breakers per day. Slide 1 of 1Get price
