Instrument cable voltage, I heard this synonym is very meaningful, yes, except for non-professionals, I believe that basically no one can correctly analyze and understand it. Looking back at the time of the middle school physics, it was really a brainstorming, but still liked this course very much. When I was in high school, I decided to read the liberal arts decisively because I could get rid of the doom of learning physics. But in fact, electricity is closely related to us, close to us, and a little more understanding of it, you can also take a more precaution against it.
450 means the ground voltage, 750 means the phase-to-phase voltage. That is to say, this line can withstand a voltage of up to 450 volts when using single-phase electricity. This line can withstand up to 750 volts when using 3-phase power. ,.

The above is all the information about the classification of the voltage level of the instrument cable that I have compiled for you. Although I am not a professional, the information provided can be safely adopted and utilized. Then let's go back to the beginning. Why do I say that if I know a little more about it, I will take more precautions? The meaning is that we are accompanied by electricity every day, and it is inevitable that we will accidentally touch it and cause harm to ourselves. Therefore, I think we need to know a little more about it.
