KS9 Series of Mining Common T ype Non-excitation


  • General
    1.KS9 series oil immersed mining transformer is suitable for central transformer substation, mining stop, general wind dypass and main wind dypass which has gas but has not explosive ganger . Moreover , it is suitable for the moisture environment.
    2.The iron cores of these series transformers are adopted silicon steel slice, which is made of excellent low loss crystal granule. They have the advantages such as low no-load loss, small no-load current and low noise


    Implementation of the standards

    JB3955-93 GB1094.1-1996 GB10942.2-1996 GB1094.3-2003 GB1094.5-2003


    Service environment

    1.Installation height do not exceed altitude of 1000m (for general), pleas point it out if it has special demand;
    2.Ambient relative humidity no exceed 40℃;
    3.Amibeitn relative humidity no exceed 95% (25℃);
    4.No violent jounce and the vertical pitch no exceed 15 degree.
