Durability
Long-Term Performance
You want a strain insulator that lasts for many years. Companies make these products to work in hard places and under a lot of stress. They test each strain insulator for how strong it is, how much it can bend, and how long it will last. These tests make sure the product is tough, even if you do not know exactly how long it will last. Picking a strain insulator means you are buying something that works in rough places and keeps your equipment working.
Tip: Always see if the product passed hard tests for long use. This helps you stop early breakage and saves you money.
Reliability Factors
Many things can change how well your strain insulator works over time. You should know what might cause trouble before it happens. The table below lists the main things in the environment and how you use the insulator that can change how it works:
