Product Description

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 IEEE and IEC60099-4
arrester are heavy duty distribution class surge arrester. These are gapless design
incorporating highly non-linear metal oxide varistor, with a discharge rated current of 10 kA. The housing can be polimeric arresters are tested in accordance with the lastest standard ANSI/IEEE C62.11 for metal oxide
arresters, and also with IEC 60099-4.
They consistently withstand the following
minimum type test:
* High Current-Short duration: 2
current surges of 100 kA-crest magnitude
20 shoots of 100 kA amplitude.
* Low Current-Long duration: 20
shoots (or impulses) of 250 A amplitude
and 2.000 μs duration.
* Duty Cycle: 20 discharges with a
current surge of 10 kA magnitude and
8/20 μs wave shape followed by 2 discharges
with a current surge of 100 kA
magnitude.

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.
