2. Trunking Cable Tray

Features:

Fully enclosed structure provides maximum protection.
Compact design resists external interference (dust, moisture, EMI).
Commonly constructed from aluminum alloy or stainless steel.
Suitable for indoor/outdoor power systems.

Applications:

Outdoor harsh environments: highways, bridges, tunnels.
Critical industrial facilities and large-scale construction projects.
