Deadends (PDI): 0.625" (16mm) Diameter Rod Deadend Insulators

Since the initial introduction in 1988, over 18 million Ohio Brass PDI's have been shipped. As the industry leader in this market segment, Hubbell Power Systems, Inc. is taking the proactive step of fully re-investing in new tooling to continue the tradition of superior quality and service. With this transition, enhancements were made on several aspects of electrical performance as well as an improved appearance as a result of new tooling.

These updates result in slightly different weathershed designs but overall the updates to our PDI-15, PDI-25, & PDI-28 will have the same mechanical function and performance as our existing designs. In addition, we are introducing a new PDI-46 design that has a slightly shorter section length than the existing PDI-35 design but meets the ANSI & CSA requirements. The current PDI-35 design will continue to be offered for those customers who have standardized on this product.

  • 1SML - Specified Mechanical Load is the tension load that a Veri*Lite insulator can withstand during a 90-second test without failure. SML is comparable to the M&E strength rating of porcelain insulators.
  • 2RTL - A Routine Test Load value is equal to 50% of the SML value.
  • 3Proof Test - The mechanical tension load applied at the factory to each insulator for ten (10) seconds.
  • NOTE: PDI Type insulators are intended for applications which are within 45° of horizontal - to allow proper shed drainage.
