Type POLIM-S Surge Arresters Maximum System Voltage …

1 Type POLIM-S Surge ArrestersMaximum System Voltage to 245 kV2 POLIM-S Metal Oxide Gapless Surge ArrestersPOLIM-S Surge Arresters are used for the 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 design where low weight, reduced clearances, flexible mounting, and shatter-proof housing is POLIM-S Surge arrester has been verified to meet station class requirements of IEEE (IEEE Standard for Metal-Oxide Surge Arresters for AC Power Circuits) and Line Discharge class 3 requirements of IEC 60099-4 (IEC Standard for Metal-Oxide Surge Arresters without gaps for AC Systems).

The POLIM-S Surge arrester now has a new construction to enhance overall lifetime performance. The metal oxide disks are enclosed in a support assembly consisting of reinforced epoxy/fiberglass loops connecting the upper and lower aluminum end pieces.

4 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 in / 222 mm to in / 254 mm diameter bolt circle along with 4-hole NEMA pad, and line and ground terminals for electrical silicone based housingThe silicone rubber housing features high tracking and arc resistance, excellent hydrophobic properties, and resistance to weathering, UV radiation and (Mylar)Stainless steel nameplates available. To select, add SN to the end of the style number. (Example: Q015SA012 ASN)Reduced electrical clearancePolymer construction has resulted in much smaller housing dimensions in comparison with porcelain units of the same Voltage rating.

5 This size reduction enables efficient use of space for switchgear enclosures, mobile substations and other applications where space restrictions are POLIM-S Surge arrester is less than 50 percent the weight of its porcelain counterpart, which results in easier handling and resistantPolymer construction reduces possible shipping and handling damage, as well as, damage due to construction provides greater protection for personnel, as well as, nearby planQuick selection guide4 POLIM-S Metal Oxide Gapless Surge ArrestersSystem VoltageSurge ArresterANSI/IEEE RatingsMaximumVm(kVrms)NominalThree-Wire Vn(kVrms)Four-WireVn(kVrms)Three-Wire Vr / VMCOV(kVrms)Four-Wire GroundedVr / VMCOV(kVrms)Four-Wire Grounded High ImpedanceVr / VMCOV(kVrms)Medium / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / / 1733 / / / / 2242 / / / 4812311596 / 76145138120 / 98170161144 / 115245230192 / 152 KeyVn Nominal System Voltage per NEMA Maximum System Voltage per NEMA Duty Cycle Rated Voltage per IEEE Maximum Continuous Operating Voltage per IEEE Temporary Overvoltage SPL Switching Protective Level 500 A 3-132 Vr (kVrms) 1000 A 144-198 Vr (kVrms)
