manufactures effective surge protection device with the
modern technology of highly non-linear Zinc
Oxide Varistor blocks and thus diverts natural lightning
surge and switching surge to earth and simultaneously
clip off
any follow on current. Our station class arresters are
designed to provide maximum safety to personnel and
sub-station
equipment even at the enormous short circuit duty.
Research and Development is an ongoing process at
Elektrolites
with the active collaboration of experts in the
industry.
