The invention provides an isolation enclosure wall, and belongs to the technical field of isolation protection of electrical equipment. The isolation enclosure wall comprises a plurality of connectioncolumns, adjustment mechanisms and ground gripping mechanisms; the adjacent connection columns are sequentially connected through telescopic fences to form a surrounding area; the adjustment mechanisms are used for adjusting the positions of the connection columns in the X-axis, Y-axis and Z axis directions, and the Z-axis direction is the vertical direction; the connection columns are rotationally connected with the adjustment mechanisms on the vertical plane and provided with rotating limiting mechanisms; and the ground gripping mechanisms are used for bearing the adjustment mechanisms andfixedly connected with the ground. The space in the isolation enclosure wall can realize various changes and adapt to most of distribution transformer platforms in different environments or differentspecifications.
