  • the land systems for telecommunications are undergoing a change mainly based on the price of copper that has been rising and has reached historical record prices, this fact has caused a strong vandalism for said metal.
  • Another weakness presented by this type of insulator is that when it is placed strictly on the front and has a cylindrical shape, it often collides or sticks with metal structures, shortening the space between the copper bar and the metal structures, which decreases the efficiency of the insulator by not exercising full body insulation.
  • the barrel-shaped or cylindrical insulators being placed between the bar and the structure vertically, the bar being below the insulator, presents a short circuit for the Isolated, this basically through the continuous water jet channel of the rain.
  • vandalism due to theft of copper and the easy disposal arrangement offered by the insulator requires the electrical industry, especially in the land system, to provide a better security against theft and that its insulator function is designed to keep the plane isolated even in rain.
  • Figure 4 is a conventional isometric perspective of the insulator.
  • Figure 5 is a side perspective of the insulator.

  • Figure 13 is a side section perspective of the structure insulator.
  • Figure 14 is a top view of the rail insulator.
  • the material for the proposed insulator, body of the patent is basically resins or nylon, and its fixation must be with head screws, the guard boxes for the heads of the screws must provide a means p ⁇ r ⁇ seal the access to the head of the screw, being so that once placed it will not be possible to disassemble said elements.
  • the patent proposal as shown in Figure 4 is a diagonal insulator with a height of 44.70 mm, a width of 27.60 mm and a length of 79mm with lateral and frontal channels, which cut off the water flow between the fixing part and The opposite face that will be for the connection bar.
  • Figure 8 shows the same arrangement of insulator but this time without the rail for the dovetail and instead two perforations (No. 6) that will serve to directly fix this piece to the connecting rod, as You can notice on the back of said piece, there are the two boxes to house the screws found Figure 9 (No. 7) and once the screws are placed these cavities (No. 7) must be sealed by resins or some epoxy polymer that prevent the removal of the screws.
  • Figure 4 shows the channels for water runoff (No. 3) with a length of 57 mm and a height of 10 mm and depth of 4 mm and running on 3 sides of the perimeter of the piece, which is avoided that finds continuous channel by water jet between the connection bar and the structure.
  • Figure 12 shows the same insulator arrangement with dimensions of 21 mm wide, 57 mm high and 85 mm long, this time arranged at the top with the mentioned rail (No. 1) for dovetail and on the opposite side to this, there is a groove (No. 8) through which said piece can be embedded in the edges of an angle or structure.
  • Figure 13 shows a hole that in the deepest part is machined (No. 10) and in the final part the box to house the head of the screw find (No. 1 1), this arrangement has the function of securing the insulator to the structure as a pin and that as in all cases the box for the Ia has been mentioned Once the screw is installed, it must be sealed so that the screw cannot be removed.
  • the insulator can be fixed to a structure with double protection, using the aforementioned groove to have the screw found as a pin and the perforation arranged frontally to cross the structure, in both cases sealing the boxes arranged for Screws are found and, if necessary, having the nut and rolling exposed, be electrically welded to guarantee its permanence.
  • the patent proposal is oriented to an insulator that can be placed in the back of the connection bar and does not have access to be removed once placed, in the same way its geometry must have paths to divert the water flow due to Ia rain and thus keep the plane isolated.
  • the insulator with electrodes was placed at its front and rear ends, simulating the connection bar at the front and the metal structure at the back and 1000 volts were applied between them, without presenting an electrical break.
  • a voltage of 5,000 volts was applied under the same arrangement and there was no electrical arcing.
  • said insulators for the isolated plane fulfill their function since the ground system must be shaped by the equipotential bonding, therefore there will never be an attraction to grounding since all metal elements will be placed on the same ground. .
  • the insulators were placed on the wall and in the structure respectively and weight was applied to the center of the connection bar, thus exerting the touch of greater intensity in the insulators, thus being the results.
  • a concentrated weight was applied to the center of the 50 kg wall and structure bar and there was no mechanical damage.
  • a concentrated weight was applied to the center of the 100 kg wall and structure bar and there was no mechanical damage.
  • the insulator was placed under a rain chamber and an electrode was placed at the end where the connecting rod goes, and another electrode at the rear, a linear voltage source (alkaline battery) was arranged on one of the electrodes and in the other electrode a linear resistance (focus), thus subjecting the short circuit simulation by continuous water jet, simulating the rain and from this arrangement the following results were obtained:
  • connection bar was placed below the insulator and the part for wall or structure fixing upwards.- There is no continuity.

Abstract

L'invention concerne une pièce de fixation isolante pour barres de mise à la terre présentant diverses faces inclinées destinées à faciliter l'évacuation de l'eau de pluie afin d'éviter des courts-circuits. La pièce est faite de nylon ou d'un type de résine. Elle est dotée d'orifices filetés et/ou d'une queue d'aronde pour la fixation de la barre de mise à la terre à la pièce ou de la pièce à sa base. Une fois que lesdits orifices sont occupés par la vis correspondante, ils sont scellés afin d'éviter que la vis ne soit retirée.
