Packaging and Mounting Information

Packaging – All SVN, PH3, PH4, MVN, MH3 and MH4 arresters are packed in a wooden crate compatible for forklift use. SVNH, SVNR and SVNX arrester units are shipped vertically, with multiple units bolted to a pallet and crated. Most VL and VLA arresters are packed with each porcelain unit in a separate cardboard carton. EVP arresters above 98kV MCOV will be packaged in a wooden crate compatible for forklift use. All other EVP and PVI-LP arresters will be packaged in a cardboard carton. All packaging includes proper labeling for correct assembly upon construction. Stacking bolts, when required, are included. If needed, grading rings are packed, shipped separately, and tagged for easy identification.

Mounting holes will accommodate ½ or ¾ inch bolts. Rated cantilever strength is achieved with the use of ½ or ¾ inch bolts. Mounting bolts, nuts, and washers are not furnished with arresters. Horizontal Mounting of Arresters – Many Hubbell Power Systems substation arresters can be mounted horizontally. The first consideration is the cantilever force at the mounting point not exceed the cataloged rated working cantilever load of the arrester under consideration. This force is a calculation of the total weight of the arrester multiplied by 50% of the total height of the arrester. Other considerations such as how much residual strength is available for large conductor loading, ice loading and wind loading require a more detailed analysis. In these cases please contact your Hubbell Power Systems Representative at 1.573.682.5521 for technical assistance.
