Copyright 2006 Hubbell/Ohio Brass OHIO BRASS AIKEN, SC JULY 2006. Printed in USA RGS 10M.. 30- . Table of Contents POWER SYSTEMS, INC. Page Introduction General arrester With the introduction of the station class Type PVN, arrester Ohio Brass has expanded its line of polymer-housed Pressure arresters for distribution, substation and transmission Temporary Overvoltage applications.

2 PVN arresters are suitable for applications Polymer Housed up through 230 kV. The PVI arresters are suitable for ESP Weathershed applications up through 138 kV. These designs combine the advantages of a polymer housing and metal-oxide varistor valve blocks, and of- Seismic fer the benefits of a one piece arrester construction for Key to the Catalog all voltage ratings. Stacking of individual arrester units PVI Polymer Housed Intermediate is not required with polymer housings. Protective Dimensions and Also available are porcelain and silicone station (Type PVI VN, SVN and VL) arresters.

3 PVI All DynaVar Intermediate and Station class surge Mounting Arresters in this catalog comply with ANSI/IEEE PVI-LP Polymer Housed Intermediate class Standard In addition, they are tested to IEC 99-4.
