Abstract
Disclosed are an electric pole manufacturing apparatus having an improved distal end, capable of reducing the cost, arranging tensile cores corresponding to a design load, and providing a high quality electric pole, and a method of manufacturing the electric pole. The apparatus comprises a mold having a dividable structure; a proximal end plate mounted to one end thereof for forming a proximal end of the electric pole, with a tensile core penetrating through one side thereof; a proximal end tensile plate spaced from the proximal end plate at a constant spacing; a proximal end tensile core fixing plate having the tensile core, with one end of the tensile core penetrating through a surface of the proximal end tensile plate; a distal end plate mounted to one end thereof for forming a distal end of the electric pole, through which the tensile core penetrates; a distal end tensile plate connected to a butt-end plate using a nut for coupling to a tension shaft lifted by a fastening force of the nut; and device for coupling the distal end tensile plate and the distal end plate, to apply the tensile force to the distal end plate.
