Product Introduction
   The surge arrester is an electrical device which can not only release lightning or overvoltage energy and avoid electrical equipment from transient overvoltage damage, but also cut off current so as to avoid grounded short circuit of the system. it is connected between wires and the earth and  paralleled with the protected equipment. When the overvoltage value reaches the set acting voltage, the surge arrester can immediately operation and to allow charges to pass, limit the voltage and protect the insulation; and when the voltage is normal, the surge arrester can quickly return the normal to guarantee the power supply as well.
  As a professional SF6 test equipment manufacturer in China, our company always dedicates to development and manufacturing of HV test equipment used for Surge Arrester In 2009, our company successfully developed and launched HV test equipment which is used for surge arrester type test  in China and is unanimously favored and praised by all surge arrester manufacturers.
