Silicon Nitride Heat Shields Ring used in the Photovoltaic I

Silicon nitride heat shields and magnetic rings are mainly used to protect high voltage electrodes and are widely used in the photovoltaic industry.Heat shields and magnetic rings, as well as ceramic rings, are collectively referred to as electrode shields.Silicon nitride electrode protection cover mainly uses silicon nitride insulation, heat resistance and corrosion resistance.Compared with the protective cover of quartz and alumina which is still in use today, the service life of the silicon nitride electrode shield is more than 10 times, and it will not be electrically broken down during use, and will not be heated, nor will it be heated. Will be eroded away. Due to its own stability, in the use of photovoltaic reduction furnaces, the collapse rate of non-human factors is greatly reduced.
