    Abstract: Based on a double-circuit 35 kV transmission line co-hopping fault, combined with on-site wave recording files, arrester disassembly inspection and same type troubleshooting, and submarine cable fault location, the entire process of fault development is analyzed,and the corresponding model is established in the electromagnetic transient simulation software PSCAD/EMTDC for the over-voltage calculation.The results show that moisture inside the arrester of phase B cable terminal of tower 1 of line I and insulation defects in phase A of the submarine cable of line II are the main reasons for this double-line simultaneous outage failure. Subsequently, it is recommended that the same batch of arresters should be gradually withdrawn from shipment, and further strengthen the 35 kV submarine cable joints production specifications and technical measures to prevent the anchor damage of submarine cables.
    Key words: submarine cable; hybrid line; short circuit fault; arrester
