How is the wire and cable current calculated? After the insulation layer is applied with voltage, the current flowing through the insulation inside the wire and cable has the following four types: Iron Fence Gate,Wrought Iron Gates,Iron Gate,Forged Iron Gates Ming Yi iron arts company , https://www.mingyi-ironware.com
1. The capacitance current is generated by the polarization of the medium. In fact, the conductor and the outer pole (insulation layer) are used as a pair of electric stages to form a capacitor current of the electric appliance. The capacitor current decays exponentially with time, usually in the milliseconds. The time is approaching disappearing.
2. Irreversible current absorption Due to electrolytic conductance in the insulating material, it decays to zero after a few seconds.
3. Absorbable current refers to the displacement current of the insulating material, which reaches the maximum value at the moment of applying the voltage, and then tends to be stable, and tends to disappear after a few minutes.
4. Leakage current Leakage current is the free ion in the insulating material and the conductive impurities mixed in. It is independent of the voltage application time. When the electric field strength is not too high, it conforms to Ohm's law, and the resistance increases with temperature. Its size reflects the quality of the insulation. Strictly speaking, only the resistance corresponding to the constant electrical conduction current is the volume insulation resistance. Http://news.chinawj.com.cn
