A, Outlines:

    The LVQB-110W2 current transformer is suitable for nominal frequency 50Hz, the rated voltage is 110kV electrical power system, as electrical survey and electrical protection.

    This current transformer has the area to be few, the reliability high, installs the cycle to be short as well as use maintenance work load small and so on merits.

      This current transformer takes the main insulation by the SF6 gas gap, for the entire seal structure. 

      this current transformer uses stands upside down the type structure, two windings in the product forehead, were the recent years compare the new structure pattern. It has used the surplus space which fully a part stays behind, because and a time, two the inferior winding in identical separates the room, causes the measuring accuracy to be more accurate.

      This current transformer is the changeable specific current mutual inductor. A winding and two winding's number of windings may change change, thus realizes the different current ratio transformation. At the same time, installs in two time winding's shield tubes to be most may install 5 a ferrite core, may obtain the different combination.
