Bonneville PowerUSA performed at Portland State University and NELEast Kilbride UK. No air gap therefore no internal ionisation Light weight compared to porcelain Ease of installation Non shattering housing Optimised voltage stress grading eliminates need tooversize stress grading ring, therefore the compactseries parallel can be installed in tight spaces withoutinfringing electrical or Surge safety clearances.

2 The diameter of the series parallel design has beencalculated to reduce the radial field stress to aminimum, even under adverse PerformanceSpecification:IEC60099-4 Classification:2PH Class 310kA3P Class 3 & 4 10/20kA4P Class 4 & 5 20kA5 PClass 520kAHigh Current Performance: 100kAEnergy Capability: according to IEC60099-4(Clause table 5 and )2 PHClass 3 at Ur3 PClass 3 at Ur3 PClass 4 at Ur4 PClass 4 at Ur5 PClass 5 at UrVoltage Rating:2PH Rated Voltage from 15kV to 168 kV3 PRated Voltage from 60kV to 360 kV4 PRated Voltage from 96kV to 468 kV5 PRated Voltage from 288kV to 525 kVInsulation:Silicone Rubber HousingTypical Applications Substations Capacitor Banks DC Inter-Connections Power Transformers Cable 16:23 Uhr Seite 6 Station ClassPolymeric Surge Arresters 72PH Series ParallelSiliconeRubberHousedArresterModu leAluminiumconnectingstrapE2 Earth Clamp to suit cablesup to 16 mmE12 x M10 x 20mmHexagon headedset screws andspring washersE5 Earth Clamp to suit cablesup to 35 mmM4 Set of 2 Polyfibre BaseInsulatorsL5 Line Clamp to suit cablesup to 35 mmL3 Line Clamp to suit cablesup to 16 mmL2 Aluminium Stem 30 x 80mm highSiliconeRubberHousedArresterModuleCo rona RingSiliconeAluminiumintersectioncross-a rmCoronaShieldM73 Polyfibre Base Insulatorsconnected to galvanised steel plateE2 Earth Clamp to suit cablesup to 16 mmE12 x M10 x 20mmHexagon headedset screws andspring washersE5 Earth Clamp to suit cablesup to 35 mm3P Series ParallelL5 Line Clamp to suit cablesup to 35 mmL3 Line Clamp to suit
