CONCLUSIONS

16 Copyright © 2010 Streamer Inc. All rights reserved.

MULTI-CHAMBER ARRESTERS AND INSULATOR-ARRESTERS

1. Multi – Chamber Insulator-Arresters (MCIAs) can be developed for any rated voltage.

2. MCIAs are very competitive with conventional lightning protection means.

3. MCIAs have a great market.
