Power cabinet is one of the important equipment in communication, power, municipal and other fields. It can place other electrical equipment, cables and other important facilities. It can provide protection against electromagnetic radiation interference for these equipment and facilities.
Although the structural design of the power cabinet is very important to the service performance of the whole cabinet, some details should be handled well so that the use effect of the product will not be bad due to the carelessness of small problems.
The shielding performance of the cabinet is also an embodiment of the use effect. This performance is mainly reflected in the shielding of cabinet doors and other gaps. The cabinet door is a frequently opened component, and there will be a large gap during installation, so the shielding performance of the door directly affects the shielding performance of the whole cabinet. Conductive rubber and conductive foam are the best choice for electromagnetic shielding, waterproof and dustproof of cabinet door.
The conductive rubber strip is mainly used for sealing the power cabinet door. After the cabinet door is closed, the gap between the door and the cabinet body is bridged by the conductive rubber strip to achieve the effect of electromagnetic shielding.
Conductive foam has the characteristics of light weight, good flexibility, excellent compression fatigue resistance and good conductivity. The main material is polyimide foam with low shrinkage force, and the surface is covered with conductive cloth, which has good electromagnetic shielding effect.
Reed shield washers and edge mount washers exhibit excellent performance when sliding or direct compression is required.
The detail of the gap of the power cabinet must be handled well. It is related to the effect of dust prevention and waterproof, and also directly affects the shielding performance of the cabinet.
