Pole top support for aerial electric power lines
Top pole support for aerial electric power lines, in particular with suspended wires in which the aerial electric power lines have at least three wires and the top pole support has corresponding insulators, in particular suspended insulators, to hold the wires. According to the invention, the top pole support traces a continuous curve substantially passing by the points in which the insulating means are.
1. Top pole support for supporting three aerial electric power lines with suspended wires, on the top of a pole comprising,
a bracket adapted for being mounted on the top of said pole,
an elongated body with a shape that traces a continuous curve substantially passing through three mutually laterally displaced points, said curve being a continuous open curve, said body having a bend, a lower arm extending from said bend and mounted on said bracket, and an upper arm extending freely from said bend and spaced from and above said lower arm and said bracket,
three insulators each connected to said body at, and suspended beneath, a respective one of said points, one of said points being on said upper arm and another of said points being on said lower arm,
said upper arm and said lower arm having respective free ends separated by an open space through which a segment of one of said wires, intermediate its ends, can be passed for separating said one of said wires from said pole support without cutting said one of said wires.
2. Top pole support for aerial electric power lines according to claim 1 , wherein the insulators are respectively connected adjacent to an end of the lower arm, an end of the upper arm and an external part of the bend.
3. Top pole support for aerial electric power lines according to claim 1 , wherein said top pole support comprises a tubular element.
4. Top pole support for supporting three aerial electric power lines with suspended wires, on the top of a pole comprising,
an elongated spiral shaped body that traces a continuous curve substantially passing through three mutually laterally displaced points, said body having a first arm at one end thereof and a second arm at an opposite end thereof,
three insulators each connected to said body at, and suspended beneath, a respective one of said points, one of said points being on said first arm and another of said points being on said second arm,
said first arm and said second arm having respective free ends separated by a space for enabling a segment of one of said wires intermediate its ends to separated from said pole support without cutting said one of said wires.
5. Top pole support for aerial electric power lines according to claim 4 , wherein said first arm and said second arm have substantially symmetrical extremities when viewed through a plane transverse to an axis of the spiral.
6. Top pole support for at least three suspended aerial electric power lines adapted to be fastened on the top of a pole, said top pole support comprising,
an elongated body shaped as a continuous open curve, having a bend and two arms with respective free ends,
a bracket fastened to one of said two arms, and
three horizontally laterally displaced insulating means suspended beneath corresponding points substantially belonging to said curve, said elongated body always defining a continuous open curve when fastened to the top of the pole.
