1. Excellent voltage-ampere characteristics. 2. Good non-linear properties. 3. Easy installation and maintenance.

Station Type Surge Arrester is designed and manufactured to protect electrical equipment in the power station. The varistor used in the arrester is subjected to a series of physical and electrical tests to ensure the protective ability, and the high-level housing verifies the insulating properties. The arrester is manufactured with excellent voltage-ampere characteristics and high level of reliability and durability.
