14. Instead of sheilding wire
MULTI-CHAMBER ARRESTERS AND INSULATOR-ARRESTERS
MCIA
Instead of sheilding wire
Less wind and ice load
Less weight and cost of towers
Less direct lightning strokes
Grounding is not neccessary
Line with sheilding wire
Line without wire but with MCIAs

MULTI-CHAMBER ARRESTERS AND INSULATOR-ARRESTERS
CONCLUSIONS
Multi – Chamber Insulator-Arresters (MCIAs) can be developed for any rated voltage.
MCIAs are very competitive with conventional lightning protection means.
MCIAs have a great market.
