These arresters are typically applied to system voltages higher than 500 kV where the energy require ments are higher than required for lower voltage systems. If a high energy rated arrester is required for a lower system voltage, Hubbell Power Systems can provide these. Please contact your Hubbell Power Systems Representative at 1.573.682.5521 for more information.
