1. Excellent protective performance.
2. Good insulating properties.
3. High level of reliability and durability.
Station Type Surge Arrester is applicable for protection of the power equipment against system over-voltages and lightning surges in the power station. The arrester is developed to endure the different temperature variations. It is characterized by excellent non-linear properties, quick steep wave response, strong current-flow capacity, and anti-aging ability, etc.
