What is the primary material characteristic that anchor bolts must possess in substation foundations?

Anchor bolts in substation foundations must have corrosion resistance as a primary material characteristic because they are often exposed to harsh environmental conditions. Substations can be located in areas where they experience moisture, chemicals, and varying weather conditions, all of which can lead to corrosion over time. If anchor bolts corrode, their structural integrity can be compromised, risking the stability of the equipment they are meant to secure. Therefore, using materials that provide significant corrosion resistance ensures longevity and safety in the foundation of substations.

While flexibility, low cost, and high conductivity are important considerations in various contexts, they do not address the specific need for durability and safety against environmental factors in the context of anchor bolts in substations.
