■ Key Technical Points

● Compact Design: Accommodates more functional units in a smaller space.
● High Structural Versatility & Flexible Assembly: The 25mm-modular C-shaped section can meet the requirements of various structural types, protection classes, and operating environments.
● Standard Modular Design: Available as standard units for protection, operation, conversion, control, regulation, measurement, indication, etc. Users can select and assemble units arbitrarily as needed—over 200 types of assembly components can form cabinet frame structures and drawer units with different configurations.
● Safety: Extensive use of high-strength flame-retardant engineering plastic components effectively enhances protective safety performance.
● High Technical Performance: Key parameters meet contemporary international technical standards.
● Space-Saving: Significantly reduces the space required for storing and transporting prefabricated parts.
● Easy Assembly: No special or complex tools required.
● Optional Aesthetic and Innovative Glass Door Structure: Improves both safety and protection class, with the protection class reaching up to IP54.
