　　商用级和通用级的测试条件类似，同为加拿大和美国认可使用。通用级电缆没有烟雾浓度规范，一般仅应用于同一楼层的水平走线，不应用于楼层的垂直布线上。◎家居级-CMX级（垂直燃烧测试VertialWireFlameTest）这是UL标准中家居级电缆（RestrictedCable），适用安全标准为UL1581，VW-1。
Power cables have many advantages and occupy less land. Generally, it is buried in soil or laid in indoor, ditch and tunnel. The insulation distance between lines is small. High reliability. It is less affected by climatic conditions and surrounding environment, stable transmission performance and high reliability. It has more favorable conditions for the development of ultra-high voltage and large capacity, such as low temperature, superconducting power cable, etc. The distributed capacitance is large. Less maintenance. It's less likely to shock.

兆欧表的测量导线应使用带有屏蔽线的绝缘导线。对三相三线铠装电力电缆进行测量时，在电缆的一端进行测量，另一端必须设专人监护。分别将电缆铠甲或终端头接地线与两根电缆芯连在一起，接到兆欧表的“E“端，另一条的芯线暂时不接，待转动兆欧表的摇柄使转速达到稳定120r/min时，摇表指针指示“∞”的位置，然后将被测电缆芯线与兆欧表的“L”端相连，版权所有。此时，兆欧表的指针可能回零位，但应继续转动摇柄，指针即慢慢随着时间的延长向标尺的“∞”方向偏转，待仪表指针稳定在某一位置时，开始读数，并作记录。
