Wall penetrating casing pipe for electric power construction

The invention discloses a wall penetrating casing pipe for electric power construction. The wall penetrating casing pipe comprises a pipe body and flange heads arranged at two ends of the pipe body; the pipe body takes the shape of a corrugated pipe; an insulation coating layer is arranged on the inner wall of the pipe body. As the pipe body takes the shape of the corrugated pipe, the length of the pipe body can be adjusted freely to adopt to wall bodies of different thicknesses; moreover, as the whole pipe body is integrally formed, no foreign object can enter the pipe body; besides, the insulation coating layer arranged on the inner wall of the pipe body can perform an excellent insulation effect.
