It has recently been announced that the UK Government will spend £9.4bn on railways acrossEngland and Wales, particularly on electrification projects [www://railwaytechnology.com/news 15/01/2013]. 2,900m of new 25kV lines will be commissioned,including the refurbishment of East Coast and West Coast Mainlines and new freight linesrunning up the centre of England from Southampton. All of these lines will require newswitchgear installations.Additionally, in November 2012 Sulfur hexafluoride (SF6) - an inorganic greenhouse gas usedfor high voltage circuit breakers in switchgear - was banned for all new switchgearinstallations in the rail industry. SF6 has been the dominant solution for circuit breakers onspace constrained rail tracks for many years, and this ban will catalyse major change in theindustry.EPS wish to develop a new product which will offer a solution by developing a smaller, saferand cheaper alternative offering significant improvements over current products, which istimely both in terms of the SF6 ban, and the major investment in new railway infrastructure,detailed in the next section.Our innovation will be significantly smaller and more compact than current offerings, will beinherently safe for operators, and will operate much more efficiently thereby reduced wearand tear on parts and requiring less maintenance.
