We report on FUSE spectra of three U Gem-type, long-period dwarf novae, UU Aql, BV Cen, and CH UMa, taken during their quiescence intervals. We discuss the line identifications in their spectra and attempt to characterize the source(s) of their FUV flux distribution. Archival IUE spectra of CH UMa and BV Cen in quiescence were identified as having a matching flux level with the FUSE spectra, and these were combined with each FUSE spectrum to broaden the wavelength coverage and further constrain model fits. Multicomponent synthetic spectral fits from our model grids, consisting of single-temperature white dwarfs, two-temperature white dwarfs, accretion disks, and white dwarfs plus accretion disks, were applied to the FUSE spectra alone and to the combined FUSE + IUE spectra. We present the results of our model analyses and their implications.
