Product Description
Type of Arrester | Working Principle | Application Scenarios |
Gap-Type Arrester | Utilizes a gap to conduct high - voltage surges to the ground, interrupting the follow - current after the surge. | Commonly used in overhead power lines, especially in rural or less - critical power distribution systems. |
Valve - Type Arrester | Features a non - linear resistance element (valve) that restricts current flow during normal operation. During surges, it conducts the excess current to the ground. | Applied in substations, power plants, and high - voltage transmission systems where reliable protection is required. |
Metal - Oxide Arrester (MOA) | Employs metal - oxide varistors with highly non - linear current - voltage characteristics. It can quickly limit the over - voltage and absorb surge energy. | Widely used in various power systems, including distribution networks, industrial plants, and electrical equipment due to its excellent performance and long service life. |
Polymer - Housed Arrester | Similar to the metal - oxide arrester in principle but with a polymer housing. This provides better environmental protection and mechanical strength. | Ideal for outdoor applications in harsh environments, such as coastal areas or regions with high pollution levels. |
