Overview of electrical wiring installation inside fuel tanks of civil aircraft

The design of electrical wiring installation within civil aircraft fuel tanks is critical for ensuring fuel system safety and airworthiness. This paper systematically analyzes fuel tank wiring installation requirements, including ignition source, electrical bonding, electrostatic protection, and lightning discharge protection. It introduces design features such as environmental characteristics, component selection, and wiring isolation. Recommended installation methodologies for fuel tanks wiring are proposed to enhance fire prevention and explosion suppression capabilities, providing technical references for improving fuel tank safety.
