When installing high-voltage cables, be sure to pay attention to the raised letters on the high-voltage cable plugs. They are C, S, and L. They are used for positioning and prevent us from inserting the wrong ones. In addition, we are installing high-voltage cables. Apply silicone grease or insulating oil to isolate the air and reduce the discharge to the shell, resulting in breakdown of the cable plug.
The withstand voltage value of 75KV and 90KV high-voltage cables is also different, but the withstand voltage value of the high-voltage cable has nothing to do with the current.
