Type EXLIM-Q Surge Arresters Maximum System Voltage …

1 Type EXLIM-Q Surge ArrestersMaximum System Voltage to 245 kV2 EXLIM-Q Metal Oxide Gapless Surge ArrestersEXLIM-Q 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 and energy capability are EXLIM-Q 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 EXLIM-Q Surge arrester is designed to meet the following performance data.

3 EXLIM Arresters live up to their name: EXcellent Voltage LIMiters. The design is robust and well-matched with other apparatus in arrester is built up of one or more units. Each unit is made up of a porcelain housing that contains a single column of metal oxide varistors. Each metal oxide varistor is manufactured by ABB where the design is verified routinely through rigorous testing to ensure superior quality. The metal oxide varistors are dispersed throughout the porcelain housing with the necessary spacers as determined by the electrical design of the (Stainless steel)Aluminum flanges that house the hermetic sealing System and compress the metal oxide varistor stack are cemented to the ends of the porcelain housing.

4 The sealing arrangement in each flange consists of a prestressed stainless steel plate with a rubber gasket. In the event that the arrester is stressed in excess of its design capability, the internal pressure causes the sealing plate to deflect open, allowing the ionized gases to flow out through the venting ducts. The seal is verified on every arrester prior to routine testing. Each arrester is furnished with a mounting base, 4-hole NEMA line pad, and line and ground terminals for electrical planUnit nameplate (SSTL)Master nameplate (SSTL)Unit stacking order nameplate (SSTL)Alternate bolt hole patterns available upon selection guide4 EXLIM-Q 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)
