More Information
Summary:The utility model relates to a metal wrapping voltage transformer which comprises an iron core, a coil, a primary terminal and an insulator, and is characterized in that the outside surface of the insulator of the voltage transformer is coated with a semi-conductive body coating, and an earthing shell is arranged outside the semi-conductive body coating. The metal wrapping voltage transformer has the characteristics that the earthing metal shell is arranged outside the insulator of the voltage transformer, so that the surface of the running voltage transformer is in zero potential, thus the voltage transformer is safe and reliable; since no isolation is set, the installation space is reduced, and the assembly and disassembly of equipment are convenient.
