1 XPS Surge Arrester - System Voltage 2 kv to kv

2 XPS Station Class Silicone-oused Arresters Metal Oxide Surge Arrester XPS Protection of switchgear, transformers and other equipment in high voltage systems against atmospheric and switching overvoltages. For use when requirements of lightning intensity, energy capability and pollution are moderate. Superior design where low weight, reduced clearances, fl exible mounting, and shatter-proof housing is required. Application The XPS polymer arrester has been verifi ed to meet station class requirements of ANSI C2. (IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits). The XPS arrester is designed to meet the following performance data: Performance data Maximum system voltages (V m ) Duty cycle rated voltages (V r ) Classifying current (ANSI/IEEE) Discharge current withstand strength: igh current 4/0 µs Low current 2000 µs kv rms - 0 kv rms 0 ka peak 00 ka peak 00 A peak Energy capability: 2 impulses, (IEC CI...).8 kj / kv of MCOV Fullfi lls requirements of ANSI transmission-line discharge test for kv systems Short-circuit / Pressure relief capability Cantilever strength ka rms sym in - lbs / 0 Nm Service conditions: Ambient temperature -0 C to + 4 C Design altitude 000 ft / 80 m Frequency - 2 z ) igher strength designs available on request 2) igher altitude designs available on request 2

3 Station Class Silicone-oused Arresters XPS Direct-Molded Construction ABB s type XPS surge arrester consists of high performance metal oxide disks molded in a shatter-proof polymer housing. The XPS now has a new construction to enhance overall lifetime performance. The metal oxide disks are enclosed in a support assembly consisting of reinforced epoxy/fi berglass loops connecting the upper and lower aluminum end pieces. The silicone polymer material is then molded directly to the metal oxide loop assembly eliminating any air pockets which could cause moisture ingress over time. Each arrester is furnished with a mounting base for an 8. in / 2 mm to 0.0 in / mm diameter bolt circle along with 4-hole NEMA pad, line and ground terminals for electrical connections. 00% Silicone Based ousing The silicone rubber housing features high tracking and arc resistance, excellent hydrophobic properties, and resistance to weathering, UV radiation and pollution. Benefits The incorporation of polymer material in a station class surge arrester has resulted in many additional advantages. Among these are: Reduced Electrical Clearance Polymer construction has resulted in much smaller housing dimensions in comparison with porcelain units of the same voltage rating. This size reduction enables effi cient use of space for switchgear enclosures, mobile substations and other applications where space restrictions are present. Lightweight The type XPS arrester is less than 0 percent the weight of its porcelain counterpart, which results in easier handling and installation. Damage Resistant Polymer construction reduces possible shipping and handling damage, as well as, damage due to vandalism. Safety Shatter-resistant construction provides greater protection for personnel, as well as, nearby equipment. Nameplate ABB Inc.
