Hollow-core　negative-curvature　fibres　have　been　the　focus　of　current　research,　but　how　to　reduce　the　loss　of　hollow-core　negative-curvature　fibres　is　a　serious　problem.　This　paper　proposes　a　new　structure　of　hollow-core　negative-curvature　fibres,　that　is　numerically　simulated　using　the　finite-element　method,　and　compared　with　the　simulation　results　of　hollow-core　conjoined-tube　negative　curvature　fibres　(CTNCFs)　and　hollow-core　nested　anti-resonant　nodeless　fibres　(NANFs).　The　results　show　that,　the　LP01　mode　loss　can　reach　0.003694　dB/km　with　a　transmission　wavelength　of　1.06　mu　m,　the　LP11　mode　loss　can　be　as　low　as　0.28423　dB/km,　and　the　bending　loss　is　0.4405　dB/km　with　a　bending　radius　of　5　cm　and　a　transmission　wavelength　of　1.06　mu　m.　The　loss　is　reduced　by　an　order　of　magnitude　compared　to　CTNCFs　and　NANFs.
