The marx transformer is a static electrical machine that converts electrical energy into electrical energy via electromagnetic induction. Transformers are used in applications where alternating current at a given voltage must be supplied as alternating current at a different voltage but the same frequency. marx transformers offer high efficiency and very wide application in the electrical industry. For higher-power transformers, MARX has developed special core geometries that optimize the use of winding space. The core is laminated from cold-rolled, grain-oriented sheets. Sheets with a quality of M 165-35S (DIN EN 10107) are used. The windings are made of special enamel-coated copper wire. Copper wire with glass-fiber insulation is used for high temperature classes upon request. In addition, round profiles as well as profiles with rectangular cross-sections are used. The electrostatic shield winding between the primary and secondary windings of the marx isolation transformer is implemented by wrapping copper foil. marx Separate windings – insulation and coil body, hard paper, special polyester film, hard fabric, silicone hose, pressure plates, and other insulating materials, according to the temperature resistance class. The coil bodies used are made of thermoplastics, such as DuPont or polyamide 6, 30% glass fiber reinforced according to DIN 46484. For large power transformers, cage-type winding supports are used. They provide better heat dissipation advantages. The MARX transformer is impregnated (without fixtures) and dried in a pre-assembled state. In this way, all transformers gain additional mechanical strength as a whole during a precisely defined drying process. In addition, impregnation with synthetic resin provides protection against moisture (corrosion).
