Adjustable feed through bushing base with lifting means
Abstract:
This invention relates to providing a means to removeably mount a feed through/grounding bushing commonly used to bond together, ground and/or park power distribution cables. Many pieces of power distribution equipment have U brackets for removable attachment of accessories and temporary placed maintenance equipment. The present invention addresses holding the bushing at an angle relative to the U bracket and surrounding surface and adjustability of the bushing height relative to the U bracket for strain relief and adjusting for improved work room. Also addressed is the advantage of cable identification by numbering the wells so that a lineman may readily select the cables even after the bushing may have been set aside for equipment replacement. This is especially useful on but not limited to this invention since the U bracket mounting means is moveable and would not always provide positive identification of one end of a multi well bushing. Also provided is a means to receive a lifting means to assist in lifting and positioning the assembly especially for higher kilovolt applications. Further provided is the method of grounding the lines of a multi phase system on a common bushing in order that a lineman can rely that the entire phase system is grounded and is gives rapid visual confirmation.
