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
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
DDC Series
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 the threatening of the security of supply.
smartCOUNT
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 .
Besides our standard portfolio, we offer customized surge arrester solutions. A high degree of flexibility of our engineering and manufacturing processes and extensive internal testing capabilities allow us to create individual surge arrester solutions for your specific application.
Some examples are
- Arresters with extra-long creepage distance for installation under extreme environmental conditions
- Arresters with extra high energy absorption capacity, such as for capacitor banks or for the AC side protection of HVDC systems, Series Compensation (SC) or Static VAR compensator (SVC) applications
- Special solutions regarding surge arrester’s connection terminals or installation variants
- Arresters with customer installation / mounting variants
- Arresters with supporter function
