Abstract
A method is disclosed for upgrading insulators of a current distribution system when the voltage of the system is to be increased. New, additional insulators are coupled with the existing ones, and the coupling is accomplished without detachment of the current conductor from the existing insulator. The mounting stud for the existing insulator is unsecured from a support member, such as a crossarm, is detached from the existing insulator, and is thereafter attached to a new, additional insulator. The two insulators are then coupled together to provide increased electrical insulation, and the mounting stud is resecured to the supporting member. Time and materials are saved by not having to detach and reattach the conductor, and by reusing the existing insulator, the conductor attachment means, and the mounting stud.
Claims5
A method for upgrading a current distribution system which includes a support member for an insulator, a mounting stud that is externally threaded at one end and the other end of which is secured to the support member, an existing insulator having a threaded receptacle therein and which is thereby attached to the threaded end of the mounting stud, and a current conductor attached to the existing insulator, comprising the steps of:
- a. unsecuring said mounting stud from said support member, said mounting stud when unsecured being rotatable within a channel which extends through said support member, the mounting stud having a base that abuts the support member externally of said channel and an extension below the base which passes through said channel and external threads on the outer end of said extension and a nut on said threads, and wherein the mounting stud is unsecured by loosening the nut without removing the same from said stud;
- b. detaching the mounting stud from the existing insulator by rotation of the stud as it remains within said channel, said existing insulator including an upper conductor receiving means wherein the current conductor is received and including securing means connected with said insulator and said current conductor for retaining said current conductor with respect to said insulator and preventing relative rotation between said insulator and said current conductor;
- c. attaching said stud to an additional insulator;
- d. attaching the additional insulator to the existing insulator, and
- e. resecuring said stud to the support member, and wherein said current conductor remains attached to the existing insulator during execution of the aforesaid steps.
