Lightning Arrester, Polymer Metal Oxide Surge Arrester 3-132kv, 10ka

YH10W-15 LIGHTING ARRESTER 10kAINSTALLATION INSTRUCTION1.     GENERAL Metal oxide surge arrester (MOA) is recognized as the upto-date overvoltage protector which ,due to the inherent superior nonlinear V-A characteristics and steep-wave response of metal oxide varistors ,can suppress overvoltages to a relative low level ,thus providing a reliable protection for insulation of electrical apparatus. The basic technical parameters are complied with the technical specification of Chinese Standard GB11032-2000 which is exactly equivalent to IEC60099-4 2.     THCHNICAL DATA ZINC OXIDE PROTECTIVE CHARACTERISTICS (10kA NORMAL DUTY POLYMER)S.NoDESCRIPTIONUNITSVALUE1.RATED VOLTAGEKV15 KV2.RATED FREQUENCYHz50 Hz3.MAXIMUM 1.2 / 50 MICROSECONDLIGHTNING IMPULSE VOLTAGEKV1254.MAXIMUM RESIDUAL VOLTAGE FOR 5 KA AND 10 KA WITH 8 / 20 MICROSECOND LIGHTNING IMPULSE CURRENT WAVEKV405.HIGH CURRENT SHORT DURATION WITHSTAND VALUE WITH 4 / 10 MICROSECOND CURRENT (PEAK AMPS)KA1006.LOW CURRENT, LONG DURATION WITHSTAND VALUE 2000 MICROSECOND WAVE (CREST AMPS)A250 7.IMPULSE WITHSTAND VOLTAGE OF ARRESTER INSULATION EXTERNAL ASSEMBLY, KV, CRESTKV95 - 125 8.POWER FREQUENCY ONE MINUTE WITHSTAND VOLTAGES, KV RMS-       DRY-       WET  KVKV  3836  3.     APPLICATION CONDITION 3.1 Normal Service condition Surge arresters which conform to this standard shall be suitable for normal operation under the following normal service conditions:    Ambient air temperature within the range of -40 ºC to +40 ºC.    Solar radiation :The effects of maximum solar radiation (1.1kW/m 2)have been taken into account by preheating the test specimen in the type tests. If there are other heat sources near the arrester, the application of the arrester shall be subject to an agreement between the manufacturer and the purchaser.    Altitude is not exceeding 1000m.    Frequency of the A.C power supply is not less than 48Hz but not more than 62HZ.    Power frequency voltage applied continuously between the terminals of the arrester is not exceeding its continuous operating voltage.    Mechanical conditions ;no strong vibration.    Pollution conditions: no requirement at this time. 3.2 Abnormal Service Conditions Surge arresters subject to other than normal application or service conditions may require special consideration in design, manufacture or application. The use of this standard in case of abnormal service conditions is subject to agreement between the manufacturer and the purchaser. 5. INSTALLATION AND PRECAUTION5.1 The surge arrester is fixed to the supporting structure by fitting-bracket, and connecting its top terminal to H V wire of electrical apparatus ,which is protected ,with 8-16 mm2 copper wire, connecting its chassis cover to the terminal of operation counter, connecting the other terminal of operation counter to the ground wire, or connecting its chassis cover to the ground directly. 5.2 The surge arrester should be lain close to the electrical apparatus, which is protected ,for protective effects. When the transformer is protected ,the distance between the arrester and on the low voltage side of a distribution transformer in case any damage to the insulation caused by forward-backward over voltage 5.3 After bring the surge arrester into operating ,should be do preventive test every two years, measuring the leakage current of arrester at DA 1mA.5.4 Please don't break open the surge arresters.5.5 This product is warranted against defects in workmanship and materials .If any failure ,resulting from a defect in either workmanship or material, is occurred under the normal using within one years form the date of purchase ,we shall replace it in free of charge.Lightning Arrestors  11kV      No.DETAILUNITSDATA Type 11kV gapless type metal oxide surgearrester - Distribution class1.Nominal  system  voltagekV112.Highest system voltagekV123.Basic Insulation Level  (BIL)kV95  3.   Ratings and type of surge arrester  4.Specification to which surge arrester complies IEC60099-45.Rated voltage of surge arresterkV106.Nominal, 8/20 µs, discharge current rating ofsurge arresterkA107.Maximum continuous operating voltage ofsurge arresterkV7.38.Gapless or gapped type metal-oxide surgearrester Gapless9.Material of insulation High temperature vulcanised siliconrubber10.Rated frequency of surge arresterHz5011.Design altitude of surge arrester (above sealevel)m1 400m12.Design ambient temperature of surge arresteroC-1 to4013.Specific creepage distance of surge arrester.mm/kV25 Automatic earth lead disconnectorsrequirements  14.Automatic earth lead disconnectors to be fittedYes/NoYES      15.Corrosion protection of metal and alloy parts:galvanising specification and/or stainless steel grade To SABS 763, 316 Tests  16.Previous type test results/certificate to beprovided with bidYes/NoYes17.Routine test results/certificate to be providedon deliveryYes/NoYes18.Drawing showing dimensions of the arrestor tobe provided with the bidYes/NoYes19.Minimum one minute wet power frequencywiths
