The Dielectric Strength Test is to be performed between each pair of conductors (including ground if applicable) and between each conductor and the foil wrapped cord guard.
电介质强度试验是在每对导体（包括地）之间和每个导体与包装了金属薄片的尾档之间测量。

Shielding may also be applied to a conductor carrying a high level test voltage to prevent interference with nearby low level circuits.
承载高测试电压的导体也应该采用屏蔽，以防止与邻近的低电平电路发生干扰。
