Key Benefits
Toshiba has long been recognised as a global leader in Surge Arrester technology since supplying their first Porcelain Surge Arresters in 1932.
Today Toshiba offers a full range of Surge Arrester products including Porcelain Surge Arresters, Polymer Surge Arresters, and special application Surge Arresters for transmission lines – Externally Gapped Line Arresters (EGLAs)
Metal oxide surge arresters with external series gaps improve the reliability of transmission systems by not only protecting against lightning damage but also protecting insulator assemblies from flashovers caused by lightning.
Porcelain Type Surge Arresters up to 800kV:
- Full range: system voltage from 3 to 800kV IEC LDC 2 to 5
- Large energy absorption capability
- Extremely long life performance (high reliability)
- Compliance with International Standards IEC60099-4 etc
Polymer Housed Surge Arresters up to 550kV
Toshiba offers silicon direct moulding (up to 275kV) and composite insulating tube type (550kV)- Improved seismic safety factor
- Easy installation and handling
- Less weight
- Safer short circuit performance (directly moulded)
- Long-life performance (hydrophobic silicone rubber)
Externally Gapped Line Arresters (EGLAs) up to 550kV
Toshiba also manufactures Externally Gapped Line Arresters up to 550KV and in compliance with IEC 60099-8: 2017Metal oxide surge arresters with external series gaps improve the reliability of transmission systems by not only protecting against lightning damage but also protecting insulator assemblies from flashovers caused by lightning.
- Compact and lightweight design thanks to superior performance on ZnO disks
- No deterioration of ZnO disks and no need to disconnect devices because of series gaps (maintenance-free)
- Successful re-closing even in arrester failure
- Long-term performance based on advanced silicone technologies
