B) Other impurities are mixed in the cooling liquid of the cooling system of the high-voltage motor, which causes pipeline corrosion and blockage, and eventually leads to the temperature rise of the high-voltage motor and motor failure;
C) There are some heat dissipation problems in the radiator tube of high-voltage motor, which eventually leads to the sudden rise of motor temperature and failure.
