Zinc-Oxide Surge Arrester TEXLIM Q-C

Transcription

1 Zinc-Oxide Surge Arrester TEXLIM Q-C Protection of switchgear, transformers and other equipment in high systems against atmospheric and switching overs. in areas with very high lightning intensity where grounding or shielding conditions are poor or incomplete for important installations where energy requirements are very high (e.g. very long lines, capacitor protection). Specially suited to extreme seismic zones. Superior where low weight, non-fragility and additional personnel safety is required. Other data can be ordered on request. Please contact your local sales representative.

Uc has to be considered only when the actual system is higher than the tabulated. Any arrester with U c higher than or equal to the actual system divided by 3 can be selected. 2) With prior duty equal to the thermal energy rating of 8 kj/kv (U r ). Arresters with lower or higher rated s may be available on request for special applications. 62 Technical information ABB Surge Arresters Buyer s Guide
