电力机柜是通信、电力、市政等领域的重要设备之一，可以放置其他电气设备和线缆等重要设施。可以为这些设备设施提供抗电磁辐射干扰的保护。
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.
电力机柜的结构设计对整个机柜的使用性能固然很重要，但是一些细节问题更要处理好，才不会因为小问题的不细致导致产品的使用效果不好。
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.
机柜屏蔽性能强弱也是使用效果的一个体现。该性能主要体现在柜门和其它缝隙的屏蔽上。机柜门属于经常打开的部件，在安装时会有较大的间隙，所以门屏蔽性能的强弱直接影响整个机柜的屏蔽性能。导电橡胶和导电泡棉是机柜门电磁屏蔽、防水防尘的佳选择。
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.
导电橡胶条主要用于电力机柜门的密封，柜门关闭后通过导电橡胶条弥合门与柜体的缝隙达到电磁屏蔽的效果。
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.
导电泡棉具有重量轻、柔性好、抗压缩疲劳性优、导电性能好等特点。主材质为低压缩力的聚亚胺泡棉、外表粘覆着导电布，具有良好的电磁屏蔽效果。
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.
簧片屏蔽垫圈和边缘安装垫圈，在需要滑动或直接压缩的情况下表现出出色的性能。
Reed shield washers and edge mount washers exhibit excellent performance when sliding or direct compression is required.
电力机柜的缝隙这个细节一定要处理好，它关系到防尘防水的效果，也直接影响着机柜的屏蔽性能。
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.
