Abstract: We consider electric flux tube solutions in SU(3) gauge theory with scalar fields in the fundamental representation, for an electric field in the $λ_8$ direction (8-type). In temporal gauge, the 3-type electric field rotates within a single SU(2) subgroup at one frequency, whereas the 8-type electric field necessarily rotates within three SU(2) subgroups with at least two different frequencies. We construct the homogeneous 8-type electric field with three scalar fields and show that two scalar fields are sufficient only on a one-parameter family of gauge field backgrounds. Like the 3-type field, the homogeneous 8-type field is immune to decay through Schwinger pair production of gauge bosons. We then construct an 8-type electric string solution in temporal gauge. Its electric field is of 8-type on the string axis and, unlike the 3-type string, the string is only net color neutral, which results in a weak radial electric field.
