The invention provides an insulating wall for power system stations, which includes a number of insulating bricks and conducting poles. The insulating bricks are connected by bonding or inserting to form an insulating wall body to achieve insulation against ground. Each conducting pole penetrates one insulating brick, and is used for being connected with power equipment inside and outside a substation and a converter station. According to the insulating wall for power system stations provided by the invention, the multiple insulating bricks are connected by bonding or inserting to form an insulating wall body structure to achieve insulation against ground, and the insulating wall is connected with the power equipment inside and outside the substation and the converter station through the conducting pole penetrating one of the insulating bricks. The external insulation margin is large, and the internal insulation problem existing in wall bushings is avoided. The insulation safety of power connection between incoming and outgoing lines of the substation and the converter station of the power system is ensured, and the construction cost can be greatly reduced.
