The present invention relates to an insulated connection adapter for an underground transmission line and, more particularly, to an insulated connection adapter for an underground transmission line, capable of easily connecting the transmission lines and preventing the permeation of rain from the outside. The permeation of the rain through a boundary between a first body part and a second body part is fundamentally prevented by forming the boundary between the first body part and the second body part with a tube expanded in the first body part and the second body part. Thereby, a short circuit due to contact with fluid is previously prevented. |
