PURPOSE: An insulator type wire support of a utility pole for fixing an overhead feeder is provided to improve work efficiency by folding and unfolding an insulator for supporting an overhead wire. CONSTITUTION: An installation guide groove(GH) is formed on outer circumferential surface of a utility pole(P). A pair of first and second wire supports(F1,F2) is arranged in parallel across the utility pole. A position fixing protrusion(200) is respectively protruded from the surface facing to the first and second wire supports. A working cylinder(100) is respectively fixed to one side of the first and second supports. A bolt hole(310) is formed on the upper surface of the first and second wire supports.
