The utility model discloses a structure is arranged to high tension switchgear's generating line, including A looks generating line, B looks generating line, C looks generating line and insulating base, its characterized in that: insulating base both ends shaping respectively have and are used for and preset some and indulge to revolve cabinet lateral plate matched with ultrasion vibration sysytem, it has the three installation port that extends just equidistant range along its length direction to open on the insulating base, wherein, the lower extreme of A looks generating line, B looks generating line and C looks generating line is arranged in proper order and is matched with three installation port respectively and be connected, the clearance of an arbitrary generating line in A looks generating line, B looks generating line and the C looks generating line is not less than 125mm and creepage distance is not less than 240mm, overcomes current straight line and appears the generatingline and be unfavorable for that the cabinet body to the shortcoming of standardized with miniaturized development, adjusts bus structure and arrangement to effectively utilize the switch board space,portably change the generating line installation, the production safety is improved.
