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 -40ºC to +40ºC.
  Solar radiation :
  The effects of maximum solar radiation (1.1kW/m2)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 PRECAUTION
5.1 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.
