The discharge plasma needle releases high voltage to break down the air and form a flame-like hot plasma beam. Since the plasma needles transmit high-voltage electricity, when the plasma needles are close to each other, discharges such as corona discharge and creepage are likely to occur between the plasma needles, causing arc damage to the furnace head and shortening the service life of the product.
