INSULATING PIPE FOR PROTECTION OF UNDERGROUND TRANSMISSION LINE

摘要

PURPOSE: An insulating pipe for protecting an underground transmission line is provided to safely protect the underground transmission line from an external force by simply improving a structure. CONSTITUTION: A cylindrical transmission line holding pipe(110) is made of a synthetic resin. A plurality of drain holes(210) is formed on the lower section of a protection pipe(200). A support piece(310) is installed in the protection pipe. A support rod(320) respectively passes through the four side of the protection pipe. A finished piece(330) is fixed to the end of the support rod passing through a stretchable piece(400). A buffer spring(340) provides elasticity to the stretchable piece.
