Hendrix stepped up in a big way

“Avangrid-CMP had a large weeklong storm impacting 75% of our customers. As we needed immediate assistance on insulators, Hendrix stepped up in a big way over the weekend. When no shipping Companies were available, Hendrix rented a U-Haul and had two employees drive 4+ hours each way to deliver in under 24hours on the weekend of Christmas. Really appreciate the effort and support of Hendrix in our Storm Restoration!”

“When we used the porcelain post insulator on a single-phase line, that was on a steel pole, we had to insulate between the post insulator and the pole (could not mount the post insulator/pole top bracket directly to the steel pole).  With the ratings the Hendrix insulator has, we will now be able to eliminate the insulation between the two and frame for single phase steel, just as we would for single-phase wood.”
