Description:
Station type surge arrester is designed and manufactured to protect electrical equipment in the power station. It is characterized by excellent non-linear properties, quick steep wave response, strong current-flow capacity, and anti-aging ability, etc. All these features enhance the level of protection and reliability. Furthermore, the arrester is designed to be easy for installation and maintenance.
Features:
1. Excellent protective performance.
2. Good resistance to pollution.
3. Easy installation and maintenance.
