The “Retractable Grounding Reel” (RGR for short) is designed to discharge the static electricity of floating roof storage tanks. It is used as the equipotential bonding between the floating roof and tank shell. The lightning current and bound charge will be effectively and rapidly dissipated to the earth upon a lightning strike. Compared with the conventional bypass conductor, it will effectively decrease the possibility of a lightning-induced fire, and make it more reliable and safe.
