    Substation Station Class Surge Arrester , High Performance Metal Oxide Surge Arrester


    In power systems, metal oxide surge arresters are used to protect electrical equipments from being damaged by overvoltage.

    The surge arrester presents a high resistance state at normal operating voltage. Under the over-voltage impulse, it would be a low resistance status and release the surging current into the earth quickly so as to make the residual voltage of the equipments which are connected in parallel with it to be controlled within the required voltage and ensured the insulation and safety of the equipments.

    The type of arresters as follows:


    Main electrical parameters of 0.22kV-220kV polymer-housed surge arrester:


    Rated voltage

    kV r.m.s

    Nominal voltage of the system

    kV r.m.s

    Continuous operating voltage

    kV r.m.s

    D.C reference voltage not less than ≥kVResidual voltage ≤ kV

    2ms rectangular impulse current withstand


    4/10μs high current impulse withstand kALine discharge


    Switching impulse


    Lightning impulse

    1/10μs steep current impulse


    In power systems, metal oxide surge arresters are used to protect electrical equipments from being damaged by overvoltage.

    Service conditions as follows:

    1. ambient air temperature within the range of -40℃to +40℃;
    2. solar radiation not exceeding 1.1KW/m2;
    3. altitude not exceeding 2,000m;
    4. frequency of the a.c.power supply not less than 48 Hz and not exceeding 62 Hz ;
    5. power -frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage ;
    6. earthquake intensity ≤8;
    7. wind speeds ≤35 m/s;

    Competitive Advantages:

    Main characteristics of arresters

    a. Excellent protection feature

    Metal -oxide surge arrester is used to protect electrical equipment in power systems from being damaged by overvoltage .As the core component of an arrester ,metal -oxide resistors have a very good nonlinear volt-ampere characteristic ,which limits the overvoltage amplitude and releases the energy of overvoltage intrudes and the current passing through resistor increases rapidly .After that ,the resistor restore a high impedance state ,making the power system work properly ,through which only micor-ampere current passes under the normal working voltage .Due to such a characteristic ,the arrester can be designed to be a structure without gaps ,thus making the arrester have features of small size ,light weight and good protection .

    b. High discharge current capability

    The discharge current capability of metal-oxide surge arresters indicates that the arredters can absorb the energy of various lightening overvoltage and switching overvoltage .

    This capability of our products meets the national standard completely and even better than the standard .Indices such as 4/10µs high current impulse withstand ,2ms rectangular impulse current withstand ,line discharge class all reach the domestic advanced level .

    c. Strong power-frequency voltage withstand

    Because of various reasons such as single-phase grounding ,long-line capacitance effect and load rejection in power system ,the power -frequency voltage may rise or temperature overvoltage with high amplitude may appear ,and the arrester has the ability to withstand the rise of power-frequency voltage to a certain extent in a given period of time .This is the power -frequency overvoltage versus time characteristic of the arrester.

    d. Good contamination withstand

    Metal-oxide surge arresters without gaps have good performance in contamination withstand because it is unnecessary to consider the influence on gap discharge voltage .The minimum specific creepage distance of the insulated housing of arresters that our company mass- produces is as follows :

    20mm/KV for medium polluted conditions of Grade Ⅱ

    25mm/KV for heavy polluted conditions of Grade Ⅲ

    31mm/KV for very heavy polluted conditions of Grade Ⅳ
