Self-locking aluminum alloy wire duct

Self-locking aluminum alloy cable trunking is an electrical accessory used for organizing, securing, and protecting wires and cables. Due to its unique self-locking design and excellent aluminum alloy material properties, it is widely used in the field of electrical wiring. Below is a detailed introduction:

Structural Design

- Self-locking connection method: Common self-locking structures include elastic buckle connections, which achieve self-locking through the coordination of slots, beads, and springs. When fastened, the beads press against the slots, compressing the springs; after engagement, the springs reset, and the beads lock into the slots, securing the cover plate to the base plate. Others use concave-convex slots, double serrated convex-concave structures, etc., to tightly interlock the trunking body and cover, eliminating the need for additional screws or tools for fixation.
- Overall structure: Typically consists of side plates and upper and lower cover plates. Some trunking also includes internal partitions and support rods to enhance structural stability. Different specifications, such as 50mm×50mm or 100mm×200mm, can be flexibly selected based on requirements.

Material Properties

- Lightweight: Aluminum alloy has low density, making it lighter than steel trunking. This facilitates transportation and installation, reducing labor intensity and construction costs.
- High strength: Aluminum alloy offers high strength and hardness, enabling it to withstand external impacts and the weight of cables without deformation, ensuring the trunking's stability and service life.
- Corrosion resistance: Aluminum readily reacts with oxygen in the air, forming a dense aluminum oxide film on the surface that prevents further oxidation of the internal aluminum, providing good corrosion resistance. Additionally, surface treatments such as anodizing or electrophoretic painting can further enhance corrosion resistance, making it suitable for outdoor, humid, and other harsh environments.
- Electromagnetic interference resistance: Aluminum alloy material has good conductivity, effectively shielding and absorbing external electromagnetic interference, reducing its impact on cable systems, and ensuring the purity and stability of cable signals.

Advantages

- Easy installation: Eliminates the need for complex tools or cumbersome fixation steps. Simply align the trunking with the buckles or concave-convex slots and press gently to complete installation, significantly improving efficiency and shortening construction cycles.
- Convenient disassembly: For maintenance or modifications, the trunking can be easily opened with a gentle press or push, simplifying operations and reducing maintenance difficulty and costs.
- Safety: The self-locking design ensures the trunking remains securely in place, resisting displacement or damage from external forces or heavy objects. Smooth edges prevent injuries to hands and cables. Some trunking also features explosion-proof functionality, further enhancing safety.
- Aesthetic and tidy: Compact structure and neat wiring enhance the overall appearance of the environment. Various surface treatment options allow it to blend with different decoration styles.

Application Scenarios

- Offices and commercial buildings: Suitable for locations with frequent wiring and network changes, such as temporary line modifications or long-term planning implementations, meeting the wiring requirements of various office areas and commercial spaces.
- Industrial environments: In factories, warehouses, and other settings where equipment movement and line modifications are common, the flexibility and adaptability of self-locking aluminum alloy trunking ensure the reliable laying of power lines, control lines, and other cables for large equipment.
- Public transportation venues: Such as subways and airports, where its excellent electromagnetic interference resistance, fire resistance, and aesthetic appeal make it ideal for cable line installation, ensuring the stable operation of electrical systems.
