A lot of discussion around insulators tends to focus on material choice (porcelain vs composite). But in practice, the decision is usually much broader than that.
So below, we put together a practical decision framework in checklist form (because let’s be honest, everybody loves a good checklist 😅). It covers some of the real-world factors that influence insulator selection: environment, electrical duty, mechanical loading, maintenance access, and long-term reliability.
If you’d like to go deeper into the topic, the full article explores insulator types, performance characteristics, application considerations, and how different network conditions can shape the “right” choice.
Worth a read for anyone involved in network design, asset management, or line maintenance.
