UNDERSTAND THE RANGE
Selecting wiring duct & cable trunking
Wiring ducts organize and support conductors inside panels, while trunking encloses a cable route. Dimensions, cover design and mounting arrangement determine how the system fits the installation.
Cross-section
Match width and height to the intended conductor arrangement and service access.
Slot design
Consider conductor breakout positions, slot opening and edge treatment.
Installation
Check fixing centres, base thickness, cover clearance and cutting method.
Material
Specify the material grade, operating conditions and any required fire or substance declarations.
Typical application context
Control panels, distribution assemblies and cable routing in equipment enclosures.
Are width and height enough to choose a duct?
Also check usable internal space, cover design, fixing method and cable entry or breakout positions.
Can dimensions be customized?
Submit a section drawing, length, material and quantity. The team confirms feasibility and tooling before quoting.
