  • 1SML - Specified Machanical Load is the tension load that a Veri*Lite insulator can withstand without failure. SML is comparable to the M&E strength rating of porcelain insulators.
  • 2RTL - A Routine Test Load value that 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.
