We have been chasing this brand of insulator all over our system. We believe it had something to do with the type of polymer they used. They don't last like the others. I think it's a combo of UV, dirt, mist from chemicals sprayed on the fields... or just a poorly made product.
We had guys document a few poles with these insulators on them and they were in good shape. The next year an outage happened and those insulators were worse than the ones pictured.
