Description

Gas insulated medium voltage busbar systems for connection of capital intensive equipment (e.g. generators, transformers and switchgears). SF6 gas is chemically inert, non-toxic and non-flammable. It has been used for just under 50 years as an insulating material in both medium and high voltage apparatus, e.g. switch gear, transformers and substations. SF6-gas can extinguish electric arc. This property coupled with its excellent dielectric withstand have ensured that SF6 is the chosen insulation medium in literally millions of electro-technical apparatus world wide. SF6 gas insulation is not subject to the aging factors which usually affect other insulations over time. The above properties, together with client demand, were instrumental in our decision to expand our product range to include SF6 solutions. - For connections between SF6 insulated equipment - For connections between SF6 equipment and non-SF6 insulated equipment - For connections between SF6 insulated equipment and cable Features and benefits of installing ISOBUS MG in the above applications: Safety and Reliability - Touch safe during operational conditions due to the outer earthed metal enclosure - No phase to phase short circuit due to encapsulation of each phase by metal enclosure - Hermetically sealed system with < 1% leakage per annum - No requirement for locked rooms within facility. - Natural cooling - High voltage testing of sub-assembly components through unit assembly prior to leaving our manufacturing plant. - Quality assurance according to ISO 9001
