Multi-Chamber Arrester 20 кV



against Induced overvoltages (MCA-20-I)

Multi-Chamber Insulator Arrester 10 кV



against Direct Lightning Strokes (MCA-10-DLS)

Insulator-arrester at tests



Insulator-arrester string 35 kV



Multi-Chamber Insulator Arresters at 35 кV Overhead Line



110 kV MCIA string at pollution tests



220 kV MCIA string at impulse tests



220 kV MCIA string at steep (2 MV/mcs) impulse tests



220 kV MCIA string at ice tests





• Less wind and ice load

• Less weight and cost of towers

• Less direct lightning strokes

• Grounding is not neccessary

CONCLUSIONS



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.
