MNS Low Voltage Draw-Out Switchgear Structural Features
This switchgear has been technologically improved based on its original design to better suit China's national conditions. The cabinet body uses C-shaped profiles with a modulus of 25mm, which are connected by connectors to form various frame structures and drawer units that can meet different requirements. In the MCC cabinet, high-strength flame-retardant engineering plastic components are used to make the safety performance more reliable. At the same time, foreign functional boards are modified and combined with a modulus of 200mm, making it more conducive to the design requirements of mixed PC and MCC cabinet bodies. The extraction unit (withdrawal unit) and the cabinet body are equipped with a reliable interlocking device to prevent load-breaking under energized conditions, improving safety. In addition, the cabinet body is generally assembled from cold-rolled steel plates after passivation treatment. It can also be made of aluminum-zinc-coated steel plates according to different user requirements.
