September 14, 2023：High voltage experimental testing of reduction furnace

Details: The water-cooled cable technology has been comprehensively upgraded, and the high-voltage water-cooled cable has recently been recognized by users in Sichuan, Yunnan, and Inner Mongolia for mass production. Conventional water-cooled cables are used for low voltage and high current transmission, and are generally used to connect the power supply and furnace body of electric furnaces such as electric arc furnaces, submerged arc furnaces, intermediate frequency furnaces, and monocrystalline silicon furnaces. This time, a high voltage and high current water-cooled cable is used for the connection between the high-voltage starting cabinet of the polycrystalline silicon reduction furnace and the electrode of the electric furnace. The working voltage of 10kV has a high requirement for leakage current. During the test, the electrode end is slowly increased to 30KV, maintained for 5 minutes, and the leakage current does not exceed 2.5mA. There is no flicker, breakdown, or discharge sound, and even electromagnetic sound. Farewell to the history of relying on imports, it has made progress and expanded space in the application field, playing a key role in energy conservation and consumption reduction
