标准中规定,刮针的直径是0.45±0.01mm,在刮针和样品线导体之间施加50V电压,刮针与导体接通时限制电流为0.05A,保证了试验时的人身安全。试验开始前,从待测电缆上取750mm样品线一根,将电缆二端剥离20mm左右的绝缘,按上图将样品线固定在试验设备上,接通电源,按压开始按钮,开始试验,该点刮磨接触开关跳停后,将样品线向前移动100mm,按固定方向(可从右至左,也可从左至右)转动90°,每个方向测量一点,共4点,zui后计算时,取4点刮磨次数的平均值。国标中不同界面的电线有不同的负荷标准,
广东11选5该标准中规定的耐磨试验设备是威尔曼热系统目录号是158L238G1或等同设备,要求刮磨刀口与接触的绝缘表面成90°直角,刀口径向半径0.005英寸(约)。试验方法:取一根24英寸(约600mm)电缆,剥掉端头1英寸(约25mm)用于连接电流源,按照表2中所对应的电缆的规格选取不同负荷进行试验,电缆耐磨刀的行程是3/8英寸(约9.37mm)刮磨速度是约55次/分钟,其试验原理、步骤基本与GB/T 12528-2008附录A一致,但GB/T 12528-2008中只规定了3kV及以下的电压,没有此标准细化电压。
