SF6 Decomposition leak detection for Mitsubishi

SF6 Decomposition leak detection for Mitsubishi

A thin film (11) detection electrode (10) is formed on an insulating substrate (13). The resulting detection electrodes (10) are light-weight, and have a very high dimensional accuracy so that the number of the parts supporting the detection electrodes (10) is small and the size of the detection electrodes (10) becomes very small. By an increase in the dimensional accuracy of the detection ...
