    Result Explanation

    The switchgear cabinet features a metal-enclosed, box-type, fixed structure. The cabinet body can be fabricated using a variety of materials, including C-channel steel, 8MF steel profiles, and aluminum-zinc coated sheets. It is assembled using multiple types of connectors. The cabinet is divided into three distinct compartments: the busbar chamber, the instrument room, and the cable chamber. All components are precisely processed and manufactured using advanced, fully CNC-equipped machinery—such as shearing machines, lathes, punching machines, and bending machines—ensuring high dimensional accuracy and geometric precision. This streamlined manufacturing process not only speeds up production but also allows for flexible, customized configurations tailored to meet diverse customer requirements.

    Key Features

    1. The cabinet features an assembled design, eliminating the need for welding, resulting in high mechanical strength and a sleek, aesthetically pleasing appearance.

    2. The indoor air-insulated load switch-fuse combination unit features a mechanically interlocked device operated according to a predefined sequence, providing reliable safety protection for both operators and equipment.

    3. The load switch installed in the cabinet can be mounted either upright or inverted, depending on the incoming cable connection method.

    4. The main switch and cabinet doors both feature a mandatory mechanical interlocking mechanism, ensuring the product meets the five-protection functional requirements.

    5. The cable installation has ample space, making cable fabrication, installation, and inspection/maintenance convenient.

    6. Enclosure protection rating IP2X,

    7. The switchgear door panels are manufactured using acid pickling and phosphating, followed by electrostatic powder coating, giving the surface excellent resistance to impact, superior corrosion protection, and an aesthetically pleasing appearance. Additionally, the cabinet color can be customized according to the user's preference.
