The principle of insulated industrial doors

Insulation is a physics term. Refers to the use of a non-conductive substance to isolate or wrap a charged body. A safety measure that protects against electric shock. Good insulated industrial door is the most basic and reliable means.Ensure the safe operation of electrical equipment and lines. Prevent the occurrence of personal electric shock accidents. Insulatied industrial doors can generally be divided into three categories. Gas insulation, liquid insulation, and solid insulation. In practical applications, solid insulatied industrial door is the most widely used. And it is one of the most reliable insulating substances. There is also this technology in insulated industrial doors, and we can learn more about it next.

The principle of insulation

Insulators of the insulated industrial door are "broken down" under certain external conditions, such as heating and high voltage.Then they are converted into conductors. An insulator is also not an absolutely non-conductive object until it is broken down. If voltage is applied across the insulating material, a weak current will appear in the material. Insulated industrial door material usually only traces free electrons. Charged particles that conduct electricity before break-down are mainly intrinsic ions. Impurity particles dissociated by thermal motion. The electrical properties of an insulator are reflected in processes such as conductivity, polarization, loss, and breakdown. Insulators are subject to electrical breakdown. When the applied electric field exceeds a certain threshold, the insulator will suddenly transform into a conductor with potentially catastrophic consequences. During the electrical breakdown process, the free electrons are accelerated by a strong electric field to a high enough speed, and these high-speed electrons collide with the bound electrons. To free the bound electrons from the bondage of the atom. The new free electrons can be accelerated and hit other atoms. More free electrons are produced, forming a chain reaction. Soon the insulator will be filled with movable carriers, so its resistance will drop to a very low level. In the air, corona discharge is a normal current near a high-voltage conductor. Arcing is an abnormal, undesirable current. Similarly, the breakdown can occur in any insulator, even solids. Even a vacuum has some form of breakdown, but this breakdown or vacuum arc is related to electron emission at the electrode surface, not by the vacuum itself.

The importance of insulation

Insulated industrial door resistance is the ability of an insulating material to resist electric current.As time gose by, the insulation begins to deteriorate. leads to a decrease in insulation performance. As experienced on board, the electrical insulated industrial door is subjected to extreme operating temperatures, moisture, and chemical contamination in harsh operating environments, which accelerates the deterioration process. It is essential to always know the electrical condition of the insulation in the electrical equipment of the ship. Avoid accidents such as electric shock, fire and short circuit.

The insulated industrial door we mainly introduced above. The working principle of insulated industrial doors and the importance of insulation are introduced. The application of this technology to industrial doors greatly enhances safety of industrial doors. If you are interested, you can go to a more detailed understanding.
