Description
Standards
-
InternationalIEC 60099-4
Application
Surge arrester designed to protect 12, 24, 36 and 42 kV class components, including transformers, equipment, cable and accessories from high voltage surges resulting from lightning or switching. It has been designed to be used with the 480TB, 484TB and 489TB separable tee connectors.
Technical characteristics
- Station class (SL); Qrs = 1.0 As.
- Energy absorption 4.0 kJ/kV_Ur.
- This surge arrester is a metal oxide varistor surge arrester in an elbow configuration.
- Each arrester is tested for AC withstand, partial discharge and critical voltage prior to leaving the factory.
