| Having a greater ratioed resistance. heated in the air electrifying ,until the temperature of hotzpne surface reaches 1050±50℃,its resistivity is in the range of 600-1400m㎡/M.SCR's resistance varies with the temperature .From room temperature to 800℃.the curve of resitance-temperature is negative value and turns positive when temperature exceeds 800℃. |
