<P>PROBLEM TO BE SOLVED: To provide an insulator set in which a connection mechanism arranged at an end of a porcelain body can be easily rotated in an adjustable manner around the entire axis of the end of the porcelain body, thereby improving the efficiency of insulator attachment work on site. <P>SOLUTION: An insulator set comprises: a cap 5 fixedly attached to a leading end of a porcelain body 3 in its axis direction; and a rotator 6 having a base part 12 provided with a connection mechanism. A fixing hole 10 is formed at the center of the cap 5, and screw holes 11 are formed around the fixing hole 10 at equal intervals in the circumferential direction. A through-hole 15 is formed at the center of the base part 12 of the rotator 6, and bolt insertion holes 16 are formed around the through-hole 15 at equal intervals in the circumferential direction. The insulator set also comprises: a connecting rod 18 loosely inserted in a lockable manner into the through-hole 15 of the rotator 6 and having an end fixedly attached to the fixing hole 10 formed on the cap 5; and a fixing bolt 22 inserted into one of the bolt insertion holes 16 of the rotator 6 and having an end screwed into the selected screw hole 11 of the cap 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
