熔断管是熔断器的主要部件，它是由熔丝装在瓷管中，并在瓷管中充填石英砂，两端密封而成。额定电流在7.5A以下及额定电压 为35V的熔管，其熔丝是绕在特制的瓷芯上，如图2.a；额定电流在7.5A以上的熔体管，其熔丝是悬挂在瓷管中如图2.b。
The fuse pipe is the main part of fuse,it is made by installing the fuse wire in the porcelain pipe,filling the quartz sand in the porcelain pipe and sealing to-ends of pipe.For the fuse pipe with rated current below 7.5Aand 35V rated voltage,its fuse wire is rolled on the special por-
celain core,referening to chart 2.a.for the fuse pipe with rated current above 7.5A,its fuse wire is hang in the porcelain pipe,referening to the chart.
