Estimating the term…
The invention is related to a line post insulator suitable for overhead lines of a higher voltage value than 1000 V. One of the practical examples of the line post insulator is equipped with a swinging stirrup placed in the insulator cap. In the swinging stirrup there is a tapered hole narrowing downwardly and holding clamping jaws. The clamping jaws are constructed so that they fit into the tapered hole. Another practical example of the line post insulator is suitable for fixing a conductor and/or a tie wire. In the insulator cap of this line post insulator a slot is formed narrowing in one axial direction of the conductor or the tie wire. In the narrowing slot above the conductor or the tie wire, a tapered clamping jaw is placed into the slot. In the slot there is a clamping jaw with parallel side edges placed under the conductor or the tie wire.
A line post insulator for overhead lines designed for operating voltages higher than 1000 volts, said line post insulator comprising an insulator cap, a swinging stirrup located in said insulator cap, said swinging stirrup comprising a stirrup body portion and a pair of laterally extending pins integral therewith, said insulator cap including a central, longitudinal hole therethrough for receiving said stirrup body portion and a pair of transverse recesses for locating said laterally extending pins whereby said swinging stirrup is adapted to pivot about a transverse axis defined by the axes of said pins, said swinging stirrup including a longitudinal, central cavity therethrough defined by a pair of opposed, downwardly narrowing side walls, a bottom wall joining said downwardly narrowing side walls and a pair of opposed upwardly narrowing side walls, the upper end of said upwardly narrowing side walls defining a longitudinal, upper gap for the insertion of a line, and a pair of elongated clamping jaws extending longitudinally within said cavity for supporting opposite sides of an overhead line, said clamping jaws having side walls that conform to the shape of said downwardly narrowing side walls of said cavity, whereby an overhead line is can be clamped between said clamping jaws by the pressing force occurring between said jaws when said jaws are wedged in said cavity due to the weight of such line.
