GIS surge arrester 3ES2, metal-oxide, metal-enclosed for gas-insulated switchgear — detailed ratings on request
3ES2
Official product family in the Surge Arresters product line, Gas Insulated Arresters (3ES/T/Y) group — protects gas-insulated switchgear (GIS) against lightning and switching overvoltages
Column of metal-oxide varistor blocks diverts surge energy to earth and limits the overvoltage to the arrester's residual voltage; carries only a small leakage current in normal service
Gas-insulated, enclosed design for installation directly on the GIS, so the protective level acts immediately at the protected compartments
Belongs to the Siemens Energy GIS arrester range covering AC/DC system voltages from 72.5 kV up to 800 kV
Type-tested arrester portfolio according to IEC and IEEE standards, manufactured in Berlin, Germany and Wuxi, China
Family-specific ratings (Ur, Uc, nominal discharge current In, energy handling, dimensions) available on request
