Description

H-type silicon carbide rod (GDH): commonly used for heating and heat preservation in the glass industry. Electrical properties of silicon carbide rods: Silicon carbide rods are a kind of non-linear resistors, which are discrete at room temperature.

During electric heating, the resistance value gradually decreases from room temperature to 750℃±50℃, and the resistance value between 800℃-900℃ rises slowly, so the resistance value between 1050℃±50℃ is basically stable, and the resistance measured at this time Relatively standard, easy to use when installing.
