Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride (SF6) is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator.[7] SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, it is

ZHN3-72.5(C-GIS) - 72.5kV C-GIS - Products - …

ZHN3-72.5 switchgear designed with Vacuum Circuit Breaker, no SF6 could be emission, The leakage of SF6 is extremely lower due to the low pressure in the gas boxes. Service life of SF6 could be enough for 30 years without air supply.

Very fast overvoltages are characteristic of high-voltage metal-enclosed SF6 insulated substations. During the transient phenomenon, on the SF6 substation enclosure an undesired, short-lasting induced overvoltage may appear, which cannot be prevented easily.

Lidar - Wikipedia

Lidar (/ˈlaɪdɑːr/, called LIDAR, LiDAR, and LADAR) is a surveying method that measures distance to a target by illuminating the target with laser light and measuring the reflected light with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3-D representations of the target. The name
