Title:
INSULATOR DEVICE
Document Type and Number:
Japanese Patent JP3777217
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an insulator device by which a steel tower supporting a power transmission line can be downsized.
SOLUTION: An insulator device 10 is integrally provided with a conductor and an insulation coating body 13, and in a connection state of the conductor to a power transmission line 21, is connected to a suspension insulator 23, which is suspending supported by a steel tower 22, via a cylindrical flange 15 set on the outer periphery of the insulation coating body 13 so as to insulating support the power transmission line 21 through the steel tower 22. The closest position to the steel tower 22 can be kept away by the insulation coating body 13 so that the arm length of the support arm 22a of the steel tower 22 is shortened and arm spacing is made narrow corresponding to the kept-away distance so as to downsize the steel tower 22 to be used.
