High Voltage

High Voltage Surge Arresters up to 800 kV

Porcelain

Surge arresters in top quality porcelain housings up to 800 kV, with outstanding sealing design for longest service life, available in three construction designs

Silicon - Solid Core Design

Surge arresters with silicone housing up to 170 kV, economic and very low weight, very convenient for application as station or transmission line surge arresters

Silicon - Cage Design

Surge arresters with silicone housing up to 420 kV for applications with advanced mechanical requirements, best price/performance ratio, use as station or transmission line surge arresters

Silicon - Tube Design

Surge arresters with silicone housing as a tube design that provides highest mechanical resistance and excellent tightness, up to 800 kV, use as station surge arrester, especially suitable for very severe seismic conditions

Medium Voltage

Medium Voltage Metal Oxide Surge Arresters and Limiters up to 51 kV

Outdoor Application

MV surge arresters with silicone housing – customized solutions available through a wide range of creepage distance, fixation means, terminals and accessories

Indoor Application

MV surge arresters for protection of power transformers, metalclad switchgears and cable terminators in indoor environments-available with different possibilities of terminals and customized length adaption

DC Arresters

Surge arresters up to 4,8 kV DC for rolling stock, tram, or streetcars or for protection of DC equipment and overhead lines

Transmission Line Arresters

Effective Protection of overhead lines from lightning overvoltage to improve line availability and stability of the electrical grid. Design as NGLA-Types (Non Gapped Line Arresters) with silicone housing

Monitoring

Monitoring solutions for surge arresters for early detection of failures modes. Our “DCC series” counters, with or without leakage current measurement, and our spark control gaps can also help to detect early malfunctioning before it leads to a threatening of the security of supply.
