“…The electric fields in SF6-inSUhted transmission lines generally are shghtly nonin these fields dielectric breakdown takes place when the maximum electric field strength, which occurs only locally, attains the breakdown level for the uniform field and is not preceded by corom discharges. 9 The overall dimensions of the tubular bus could thus be made very small if hgh gas pressures were used. The following should be noted, however:…”

Two 420 kV SF6-insulated tubular bus systems, 600 m and 700 m long, have been completed in the spring of 1975. The three-phase systems consist of isolated-phase transmission lines and form the power link for the Wehr pumped-storage plant.After a brief description of the electrical data specified and of the mechanical design, the authors describe the large number of electrical tests carried out. These included laboratory tests, which were concluded by type-testing of the tubular bus and metalclad surge diverter, and routine tests on insulators and diverters. Special attention was also paid to the performance of the equipment under various fictitious fault conditions, and several test series were carried out for this purpose. For the test at the site, an oscillating switching impulse voltage was applied.

The two most commercially important sulfur‐containing inorganic fluorine compounds are fluorosulfuric acid and sulfur hexafluoride. Fluorosulfuric acid is used as a fluorinating reagent in the preparation of such compounds as boron trifluoride and silicon tetrafluoride, and as a catalyst in organic reactions for alkylation, acylation, polymerization, sulfonation, and isomerization. Fluorosulfuric acid is itself a strong acid. When combined with certain inorganic fluorides, the system exhibits superacid properties. Properties, manufacture, and uses are discussed. Of the known sulfur fluorides, sulfur hexafluoride and sulfur tetrafluoride are available commercially. Sulfur hexafluoride, nonflammable and of high chemical stability, has a high dielectric, and is used widely in electrical and electronic equipment such as circuit breakers, capacitors, microwave components, etc. Sulfur tetrafluoride is used as a fluorinating reagent. Properties, manufacture, and uses are described. Other sulfur fluorides are discussed.
