We can usually see lightning rod . Some people think it is very safe after installing a lightning rod. In fact, there is no 100% lightning protection equipment. There is no lightning strike in the protection scope of lightning protection fa

As is known to all, lightning rod is a device used to protect buildings from lightning strikes. We might think that with the protection of lightning rod, the lightning will escape and cant contact with the building. However, that is a misun

Do you know the bimetal material ? A bimetal is a composite of two or more metals materials, because of the different thermal expansion coefficients of each component layer, when the temperature changes, the deformation of the active layer

Insulating material refers to a substance that is not electrically conductive or has a small conductive electrode under the action of a direct current voltage. The main function of the insulating material is to isolate the charged conductor

Insulating materials are non-conductive materials under allowable voltage, but not absolutely non-conductive materials. Under the action of certain external electric field strength, conduction, polarization, loss, breakdown and other proces
