The solutions from static, pointlike colour source are given. There exists not only solutions with finite energy but also singular one which describes confinement. The confining potential depends on the $δ$ parameter of our model. The regular magnetic monopole solutions as well as the singular dyon configurations are also obtained. We fit the $δ$ parameter to the experimental data.High Energy Physics - Phenomenologytext
