What is a characteristic feature of both porcelain and polymer suspension insulators?

Resistance to environmental factors is a key characteristic feature of both porcelain and polymer suspension insulators. These materials are designed to withstand adverse weather conditions and environmental stresses, making them ideal for use in electrical insulators that are exposed to the elements.

Porcelain insulators offer excellent resistance to moisture, UV radiation, and chemical contaminants, which helps to maintain their insulating properties over time. Similarly, polymer insulators are engineered using advanced materials that provide superior hydrophobicity, allowing them to repel water and dirt, thus reducing the risk of electrical tracking and flashover.

By effectively resisting environmental factors, both types of insulators ensure more reliable operation in power systems, reduce maintenance costs, and prolong the lifespan of electrical infrastructure. This resilience is a significant factor in their selection for outdoor applications in electrical grids.
