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.
