Retractable grounding reel

Retractable grounding reel (RGR for short) is designed to reduce the risk of lightning damage and fire by creating a low-impedance bond between the floating roof and tank shell. The lightning current and bound charge will be effectively and rapidly dissipated to 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.

The tank floating roof shall be bonded to the tank shell by direct electrical connection through an appropriate number of bypass conductors. Each conductor, including connections, shall have a maximum end-to-end electrical resistance of 0.03Ω. The bypass conductors shall be of the minimum length necessary to permit full movement of the floating roof. Bypass conductors should be evenly spaced not more than every 30m (100ft) around the tank circumference with a minimum of two.
