Solid, Metallic Ground Bars and Their Uses
During the installation of assorted electrical and telecom room equipment, a solid metallic bar is installed. This bar serves as the center-strength ground-point for the equipment. For telecommunication, copper is used as the material for production of ground bars. For other industries, materials such as steel are preferred. An example is the bar type fabricated into different shapes, like rolling bearings, and ball bushings. The bars made of copper are used during telecom, and assorted electrical equipment installations, because they act as the equipotential ground between different service planes, and the installed equipment. This function is best demonstrated, during transient and faulty conditions. The equipotential base created by the ground bars offers close to zero voltage differentials. Due to this vital role in equipment installations engineering, ground bars play a great role in protecting the installed equipment, as well as the users of the equipment, during such adverse events. The most popular of these bars is bonding bar. The usage of these bars is on the increase, due to their high performance characteristics.
These products offer a convenient, single-point bonding, and grounding location. They come in a variety of shapes and configurations depending on the area of use. For example, those used for wireless telecommunications installations, and those which serve as perimeter bus structures for halo grounds. These products can be differentiated using their hole- pattern, which identify their area of usage, and the degree of strength they offer. Examples are the EE, HH, GG, JJ, FF, AA, BB, and the CC models.
In the recent past, the customers of ground bars have found it more economical, more convenient, and more profitable to purchase fabricated ground bars, rather than grinding their own. This has resulted from the simplification of warehousing for these consumer companies, as well as the benefit of outsourcing high quality bars. The outsourcing of these products has also resulted from the changing production patterns of consumer companies, which use a number of alternative shapes and quality specifications, depending on the sensitivity of the ground of installation.
The quality of ground bars can be checked from a number of features, including their smoothness, roundness and straightness, especially when referring to round ground bars. The feature of roundness does not apply to all ground bar shapes and sizes. These features are important during the machining process, as they allow for smooth, trouble-free production, especially when run through high speed machining. These features also allow for vibration-less, accurate feed movements during machining. An example is the machining process offered by automatic lathes. The property of straightness is also of major importance, when fabricating different components from long bars.
Ground bars, due to their superior material are further fabricated into rolling bearings, long shafts and ball bushings. Major ground bar producing companies fabricate their bars in different diameters. The diameters range between 12 and 100mm, especially among the all steel grades. Major classifications of these bars include round ground bars, fine ground bars (standard execution type) and fine ground bars (special execution type). The usage of the different classifications varies. For instance, rough ground bars are often purchased by consumers who want to fabricate them into other shapes.
Ground bars are solid metallic bars, used to offer a center-strength ground point during the installation of telecom and electronic equipment. These bars are important because they help maintain the safety of the installed equipment as well as that of the users of such equipment. These bars come in a variety of shapes, which are differentiated by the shape, diameter, size and hole patterns. These characteristics vary depending on the area of usage. The outsourcing of these products is often economical, as their production is capital laden. The qualities of these bars, for instance straightness are of major importance, as they allow for easier machining and further fabrication. The materials of ground bars vary, depending on their area of usage and strength requirements.
