Best practice for electrical safety

Download white paper

The white paper highlights the need for ensuring efficient cable bonding where cables enter compartments and equipment as well as cable shielding where cables enter a shielded structure. It also discusses the importance of diverting lightning currents from, and reducing their effects on, electrical installations since they frequently cause damages to electrical equipment.

Very effective diversion

The white paper presents results from cable bonding efficiency tests conducted on different configurations. One of the configurations involved external connections through cables, including a “pigtail”, another one was based on the modern Roxtec BG™ solution for cable sealing, bonding and grounding. The Roxtec BG™ solution was used to demonstrate the high efficiency that can be obtained from a properly made bonding of cables at the cable entrance of a shielded cabinet. The objective was not to evaluate the performance of the Roxtec BG™ seal as an individual component, but to show that proper bonding can result in very effective diversion of unwanted currents brought by the cables.

The Roxtec solution has a cable bonding efficiency exceeding 99%.

Significant differences

In fact, the traditional earthing kit using a “pigtail” had a bonding efficiency of approximately 62%. The Roxtec solution, however, came in at a cable bonding efficiency exceeding 99%. The test results show that the effectiveness strongly depends on how the bonding is made.
