The static longitudinal and transverse gluon propagators in the Landau gauge are studied in lattice QCD with nonzero isospin chemical potential 
. Parameterization of the momentum dependence of the propagators is provided for all values of the chemical potential under study. We find that the longitudinal propagator is infrared suppressed at nonzero with suppression increasing with increasing . It is found, respectively, that the electric screening mass is increasing with increasing . Additionally, we analyze the difference between two propagators as a function of the momentum and thus compare interactions in chromoelectric and chromomagnetic sectors.
