The present invention refers to an improved bar best know as multi-articulated bar, which concentrates all and each of the grounded conductors pertaining to different equipments and electric housings in order to equalise the potential difference and finally lead and discharge it to the ground mesh. The purpose of the present invention is to provide a type of bar totally different from those currently available on the market since it has a multifunctional construction, which main characteristic is that it reduces short, half and long term costs; on the one hand, the reproduction cost of the bar is low as the raw material thereof is cheaper than copper, on the second hand, said raw material is not as attractive as copper is to thieves, thereby providing excellent results and reducing risks as the joints are not weather exposed but located at the inner portion of the bar, which has a stainless steel cover for preventing external agents from entering. |
