The specimens shall be subjected to an applied ac potential that is increased from near zero at a uniform or nearly uniform rate that is not less than 100 per cent of the potential rating of the wire or cable in 60 s and is not more than 100 per cent in 10 s (the rate of increase is not to exceed 500 V/s in

你想翻译整个句子吗？

可以的话，就翻译整句，主要是后面的不太懂，麻烦诸位了

大意如下：

在试样上施加交流电压，试验电压应从接近零开始以匀速或近似于匀速上升，升压速度应在60秒内升至不小于电线或电缆额定电压的100%,在10秒内升至不大于产品额定电压的100%(任何情况下升压速度不得大于500V/s)。

谢谢，受用了
