  We present the analysis of medium-resolution spectra obtained at the Southern
African Large Telescope (SALT) for nuclear globular clusters (GCs) in two dwarf
spheroidal galaxies (dSphs). The galaxies have similar star formation
histories, but they are situated in completely different environments.
ESO269-66 is a close neighbour of the giant S0 NGC5128. KKs3 is one of the few
truly isolated dSphs within 10 Mpc. We estimate the helium abundance $Y=0.3$,
$\rm age=12.6\pm1$ Gyr, $[Fe/H]=-1.5,-1.55\pm0.2$ dex, and abundances of C, N,
Mg, Ca, Ti, and Cr for the nuclei of ESO269-66 and KKs3. Our surface photometry
results using HST images yield the half-light radius of the cluster in KKs3,
$\rm r_h=4.8\pm0.2$ pc. We demonstrate the similarities of medium-resolution
spectra, ages, chemical compositions, and structure for GCs in ESO269-66 and
KKs3 and for several massive Galactic GCs with $[Fe/H]\sim-1.6$ dex. All
Galactic GCs posses Extended Blue Horizontal Branches and multiple stellar
populations. Five of the selected Galactic objects are iron-complex GCs. Our
results indicate that the sample GCs observed now in different environments had
similar conditions of their formation $\sim$1 Gyr after the Big Bang.
