从China供应商批发进口Ac Gapless Metal Oxide Arrester — FOB条款

I. Use AC gapless metal oxide arrester (hereinafter referred to as arrester) is used to protect AC electrical equipment of corresponding voltage level from lightning overvoltage and operating overvoltage damage. Product Implementation Standard: GB11032 - 2010 "AC electrical equipment arrester". II. Conditions of Use 1.It is suitable for indoor and outdoor use. 2.Ambient temperature (-40 +40) C;O 3.The maximum solar radiation intensity is 1.1kW/m.2 4.The altitude does not exceed 2000 m. 5.The rated frequency of AC system is (48-62) Hz. 6.The power frequency voltage applied between the arrester terminals for a long time should not exceed the continuous operating voltage of the arrester. 7Earthquake intensity 8 degrees and below; 8.The maximum wind speed does not exceed 35m/s. III. Structure and Characteristics This kind of arrester is assembled by superposition of non-linear zinc oxide resistors and sealed in high voltage insulating ceramic sleeve without any discharge gap.Under normal operating voltage, the arrester is insulated with high resistance; when it is impacted by overvoltage, the arrester is in low resistance state, releasing impulse current into the ground quickly, so that the voltage on the electrical equipment parallel to it is limited to the prescribed value, so as to ensure the safe operation of the electrical equipment.The arrester is equipped with a detachment device. When the arrester operates under overload or suffers accidental damage, the internal pressure increases sharply, so that the arrester can be detached from the device to ensure that the ceramic sleeve is not damaged.The arrester has the characteristics of good steep wave response, high shock current tolerance, low residual voltage, reliable operation, no power frequency continuous current, simple maintenance and so on.
