TEXLIM T264-CV362

This surge arrester provides protection for switchgear, transformers and other equipment in high voltage systems against atmospheric and switching overvoltages.

Especially suitable for applications where:

–  The installation location is in an area with very high lightning intensity

–  Grounding or shielding conditions are poor or incomplete

–  The protected equipment is of especially importance

–  Energy requirements are very high (e.g. very long lines, capacitor protection)

–  The seismic level is considered extreme

 

The TEXLIM T-C is superior where low weight, non-fragility and additional personnel safety is required.

Each crate contains a certain number of arrester units and accessories for assembly and erection. A packing list is attached externally on each crate. Each separate crate is numbered and the numbers of all crates and their contents are listed in the shipping specification. Hitachi Energy reserves the right to pack arresters in the most effective/economic combination. Alternate or non-standard crates may involve additional charges. The table above is to be seen as an approximation and specific data for deliveries may differ from the values given.
