- Standard : IEC 6009
- Systems used : 6.6 kV, 11 kV
Application
Surge arrester is a device to protect electrical equipment such as terminal equipment switchgear, power cables and pole mounted transformers from over-voltage transients caused by external (lightning) or internal (switching) events.
Specification
- Silicon rubber housing. Housing designed to avoid pockets in which water can collect.
- Installed phase to ground
- Arresters of void free construction and all joints hermetically sealed.
- Suitable for horizontal and vertical mounting
