The present invention relates to a protection pipe for insulation mounting an underground distribution line. Provided is the protection pipe for insulation mounting the underground distribution line, which comprises a first power generation unit and a second power generation unit including a piezoelectric element compressed to the downward of a second cable body and the downward of an upper plate by the pressing to generate electricity. The power generated from the first power generation unit and the second power generation unit is accumulated as a battery such that the power can be used as a power source when transmitting warning sound, thus, securing power at all times regardless of weather. According to the present invention, the protection pipe can prevent the damage of underground distribution line caused by an external force and prevent electrical accidents in advance, and provide a stable power supply to means for sending warning sound when applying the external force to prevent the distribution line from being broken in advance. |
