<p>PROBLEM TO BE SOLVED: To obtain a power-supply pole in which a power-supply cable can be housed easily, in which an appliance body can be attached simply to a pole and whose construction property is enhanced,by a method wherein the tension stop part of the powersupply cable is formed near the tip of the pole which is erected and installed in such a way that its lower part is buried in the ground. SOLUTION: A power-supply pole 1 is constituted while a pole 2 which is erected and installed in such a way that its lower part is buried in the ground G, and an appliance body 3 which is installed at the tip of the pole 2, are contained. In addition, the appliance body 3 is constituted while a base 4 and a casing 5 which is installed at the upper part of the base 4 are contained. The pole 2 is a cylindrical steel pipe, and its upper end part is provided with a tension-stop fixation plate 20 which protrudes from the inside. In addition, a power-supply line or the like is wired through a corrugated rigid sysnthetic resin pipe F when it is buried in the ground so as to be wired. In the pole 20, a through hole which is used to attach and mount the tension-stop fixation plate 20 and a hole which is used to place the base 4 so as to be attached and mounted are bored and formed. As a result, when the appliance body 3 is attached to the pole 2, the power-supply line is housed easily, the appliance body 3 can be attached to the pole 2 simply, and the construction property of the power-supply pole 1 is excellent.</p> |
