Claims

[Scope of utility model registration request]

(1) In a porcelain insulator used in electrical equipment such as bushings and current transformers, a tapered top piece whose upper diameter is the diameter of the upper part of the insulator that is necessary for the lowest voltage range of the equipment used; a lowermost piece whose lower diameter is the diameter of the lower part of the insulator tube required for the highest voltage range;
Above 1. It is sandwiched between the upper piece and the lower piece, and the lower diameter of the upper piece and the top of the lower piece □
Predetermined pieces are selected from a group of pieces consisting of a plurality of tapered intermediate pieces formed to have the same diameter, and are connected to form a tapered insulator pipe of a desired thickness and length. An insulated pipe characterized by:

(2) The insulator pipe according to claim 1 of the utility model registration claim, in which a flange is attached to the lowermost piece.

(3) The insulator pipe according to claim 1 or 2, wherein the lowermost piece is a right cylindrical piece.
