PROBLEM TO BE SOLVED: To provide a reconstructing method of a strain steel tower, which can reduce the number of charge part stopping days or a modification cost by decreasing the modification amount of members.;SOLUTION: A new steel tower is constructed while ensuring a work safe distance by a modified arm 23 obtained by modifying an arm of an existing steel tower 100 to be long. At that time, a strain insulator sting is changed to a suspension insulator string to suppress torsion force generated on a tower body, and the amount of steel tower modifying construction is reduced to decrease the number of stopping days or a construction cost. Existing strain clamps in a fore-and-aft span are coupled by a supporting wire, thereby suppressing the generation of electric wire construction which requires expensive construction costs. The supporting line is made to be an electric wire of the same kind as that of the span, thereby making a suspension device compact, and enabling the suspension device to be applied for a facility having long insulator length.;COPYRIGHT: (C)2013,JPO&INPIT
