  • Heavy transport solutions • Aerofilm Systems • Freedom to move

    Heavy transport solutions. Air and water casters are ideal for moving extremely heavy weights. Transformers, ships and parts of ships such as azipods, cable baskets and other weights up to millions of pounds have been moved and positioned with air or water casters for years. By creating a wafer-thin film (water or air) between your transformer, cable basket or ship and the floor, the whole thing floats.

  • Isolation transformer - Wikipedia

    An isolation transformer is a transformer used to transfer electrical power from a source of alternating current power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load. This isolation is used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must
