Definitions

  • the land systems for telecommunications are made up of conventional grounding bars, which could be detailed as: 100% solid copper bars, 24 inches long, 2 inches wide and with a thickness of 3/8 inch, with 9 holes, all 3/8 inch in diameter, through which the equipment is landed to the earth mesh, and two side holes 9/16 inches in diameter, which are used to fix the bar.

  • the current grounding bar is very expensive since its main component is copper, which in the international markets has had a substantial increase, but it is even more expensive, with its large-scale theft and with the damages that can be caused to the telecommunications equipment in the radio bases or centrals, in the period that the area is left unprotected due to its theft, that is to say during the period of time that implies the new installation of the bar.
  • Figure 2 is a conventional (isometric) perspective exploited from the bar.
  • Figure 3 is a side perspective of the bar, (side section)
  • Figure 4 is a front perspective view of the bar.
  • Figure 5 is a top perspective of the bar.
  • Figure 6 is a front isometric perspective armed with the bar.
  • this bar has 18 3/8 inch male-bore holes at its front, with a horizontal separation of 58.20 mm and 25.00 mm vertically between its centers (No. 3), being introduced into each of These holes, an oppressor screw are made of 3/8 inch by 3/8 inch long stainless steel, whose purpose is to hold the grounding conductors (No. 4). On its back it has two dovetail slides (No. 1), where the supports will be inserted for fixing to a metal structure or wall.
  • the bar has in its upper part with nine transverse holes (No. 2), through which the grounding conductors will be introduced, being the case that the first transverse hole from left to right, has a cover of stainless steel, thereby avoiding the galvanic torque (No. 6), in addition to said holes having an insulating plug, designed specifically to avoid the introduction of water and / or any other agent into them. (No. 5)
  • the construction of the bar is based on a single piece of aluminum or Galvanized Steel, as shown in Figures 2 and 3, with a length of 500.00 mm, 50.75 mm wide and 25.04 mm thick, which is obtained after carrying out the cuts and perforations through milling machine and other instruments.
  • the work efficiency of the bar is that because it is manufactured in a suitable material such as aluminum or galvanized steel, its production costs are reduced and its robbery is minimized, as well as the null introduction of water by runoff and external agents such as corrosion and oxidation, caused by the environment.

  • the design and the material of the bar constitute, to a large extent, the novelty of this, since in the first place, its dimensions are adjusted to the needs of the user, since it can cover from one to nine groundings.
  • Another of the benefits of this new device is that by the materials of which it is formed, its corrosion and oxidation is minimized, before its exposure to the environment, with which the conductivity of the energy is optimized.
  • this new device has the quality of having a faster connection, since no specialized tool is required (terminals mec onic ⁇ s or compression, insulating sleeves), because the stainless steel oppression screw with head find, allows a simple and quick installation.
  • the bar for its conformation materials that can be made of aluminum or galvanized steel, have defined values for electrical conduction and thermal shock, this information is concentrated in the Onderdonk equation and is highly used in the electrical industry as part design parameters intended to conduct electric current. These values determine if a piece of metal is capable of conducting an indicated value of electric current in a set time. Therefore and based on the statistical data by CIGRE (International Conference of High Voltage Electrical Systems) France has defined values and failure times for atmospheric discharges or lightning. These ranges are what we have used to assess the conditions to which said bar could be exposed, since in many occasions it will be outdoors and therefore can be subject to a direct impact of lightning.
  • CIGRE International Conference of High Voltage Electrical Systems
  • the design of the bar in aluminum or galvanized steel has a cross section of 6000 mm2, and meets and exceeds the required cross section, without presenting damage to its mechanical structure.

Abstract

L'invention concerne une barre métallique de connexion de câbles de mise à la terre, permettant de fixer solidement lesdits câbles par la pression d'une vis Allen. Les orifices pour les câbles se situent dans les faces supérieure et inférieure de la barre, protégés par des bouchons. Les orifices filetés pour les vis sont formés dans la face avant de la barre. Le nombre de connexions possibles dans ce cas particulier est de neuf. Le câble de dérivation à la terre de l'ensemble présente un revêtement en acier inoxydable. La barre est faite d'acier galvanisé ou d'aluminium et sa fixation au mur s'effectue au moyen d'un canal coulissant de type 'queue d'aronde'.
