New Enhanced Varistor Protection (EVP) arresters are now available, superseding the Ohio Brass PVN family of arresters.
Built on 20 years of Ohio Brass by Hubbell Power Systems experience, EVP arresters have a robust sealing system. A slotted tripod base gives flexible installation fitting 8.75-inch and 10-inch (22-cm and 25-cm) bolt circles. Grading-ring usage is optimized. EVP arresters offer the same housing material, mechanical strength, protective level and energy rating as the Ohio Brass PVN arrester family.
