II. Model and Its Meaning
XL-21 Power Distribution Cabinet: X denotes the control box; L stands for power; and 21 indicates the sequential number of its design and development.
III. Structural Features
1. The XL-21 power cabinet is installed independently, and its top features a removable cover plate for convenient busbar installation and removal.
2. The enclosure can be divided into indoor and outdoor, enclosed-type distribution boxes. The enclosure is fabricated by bending and welding thin steel plates, with the door panel and rear cover plate designed as removable components. Additionally, the mounting plate and side beams are adjustable, allowing for flexible and convenient installation, maintenance, and inspection. The design is compact, highly versatile, and easy to use.
3. Equipped with precision-cast adjustable door hinges, allowing the door to open beyond 135°.
4. After the components are installed, the mounting brackets inside the enclosure can be adjusted as a whole.
5. It can be installed and wired in/out according to different usage environments, offering high versatility and allowing multiple units to be used in combination.
