Thanks to its excellent insulation properties, SF6 gas is increasingly used in high voltage switchgear, circuit breakers and other electrical equipment.
Decomposed SF6, however, contains toxic and corrosive gaseous and solid decomposition products. As a fluorinated gas, just 1 kg of SF6 equates to 22,200kg of CO2, posing a significant threat to air quality.
In many cases we can reclaim decomposed SF6 gas to make it reusable, using processes that comply fully with British Standards IEC 60480 and IEC 60376.
At Hornbill, we understand how to harness the significant technical advantages of SF6 while adhering to environmental regulations and minimising the potential environmental impact of this potent gas. Our high voltage maintenance teams are fully trained to manage SF6 gas in the working environment and exercise the utmost care when handling, processing and monitoring the gas.
Using specialist test equipment to assess, evacuate and charge high voltage equipment, Hornbill's engineers will ensure that your SF6 gas installations comply fully with all engineering and environmental requirements.
We also maintain close links with gas suppliers and reprocessing companies. This means we can provide full support for all your high voltage equipment that contains SF6 gas.
