This poster made of mosaic tiles by French craftsman Michel Thévenot references the Sulphur Hexafluoride (SF6) substation named "Fluobloc" developed by French electrical firm Delle-Alsthom. It was mounted on the walls of Jurong Power Station's 66kV switch-house, which contained SF6 gas circuit breakers manufactured by Delle-Alsthom in 1972. It documents an essential aspect of Singapore's power generation history when SF6, an inert gas, became widely adopted in place of oil, for the insulation of high-voltage electrical equipment including circuit breakers, transformers, and switch gears. The gas-insulated technology played a vital role in modernising electrical substations, allowing for the construction of more compact and efficient facilities. Jurong Power Station was officially opened by then Finance Minister Goh Keng Swee in 1970. It was the fourth power plant to be built by the Public Utilities Board (PUB), in response to the high demand for electricity by industries and consumers from the 1960s. It was located in the expanding Jurong Industrial Estate to support the nation's industrialisation drive. The station's old steam plant was eventually decommissioned in 2001, while the open cycle gas turbine plant was decommissioned in 2024.
