    SF6 Gas Insulation Standalone Current Transformers

     

    The standalone current transformer is for the current measuring and protection for the power systems.

    Rated voltage: 40.5kV~550 kV

    Rated primary current: 50~8000A

    Rated secondary current: 1A, 2A, 5A

    Rated frequency: 50Hz or 60Hz

    Maximum output: 200VA(GB, IEC AS standards), or B-1.8, C800 (IEEE standard)

    The accuracy classes: 0.2S, 0.2, 0.5S, 0.5, 5P, 10P, PX, PR, TPY, TPZ (GB, IEC AS standards), or 0.15, 0.3, C (IEEE standard)

    The bushing is made by silicon rubber or porcelain

    外壳由铝合金铸造而成,有SF6密度监测仪监测气体压力,并带有泄压装置,生产非常安全。绝缘材料为SF6气体,泄漏量不超过0.1%/年。局部放电小于5PC。

    产品使用寿命很长,30年以上甚至40年,无需任何特殊维护。我们的技术已达到国际领先水平。
