The Niedax LLK 26.030 is a mini cable protection duct made of strip-galvanised steel, designed for concealed or exposed installation of electrical cables in indoor environments. It features a snap-on lid, enabling secure and quick installation. Mounting is achieved via a single-row perforation in the duct base, with hole spacing arranged at 250 mm intervals. Dimensions are approximately 26 mm height and 30 mm width, with a standard delivery length of 2000 mm. The usable cross-section is 730 mm², providing sufficient capacity for routing multiple cables. The material complies with DIN EN 10346, ensuring the quality and corrosion resistance of the strip-galvanised steel.

Cable protection duct

The LLK 26.030 serves as a closed conduit element for electrical cables, protecting them from mechanical stress, contamination, and external influences. It is typically used in electrical installations, particularly in residential and commercial buildings, where proper and safe cable routing is required. The design enables clean and structured cable routing, facilitating maintenance and inspection of the cables.

Functions and equipment in detail

A central feature is the snap-on lid, which allows easy installation and removal without requiring additional tools. When snapping the lid into place, equipotential bonding is automatically established, enhancing electrical safety. The single-row mounting perforation in the duct base, with dimensions 4.2 x 12 mm and 7 x 15 mm, offers flexible mounting options on various substrates. The 250 mm grid spacing enables even and stable mounting.

Technology explained clearly

The duct is made of strip-galvanised steel, providing high mechanical strength and corrosion resistance. Galvanisation according to DIN EN 10346 ensures a uniform protective layer, extending the product’s service life. The automatic equipotential bonding function when snapping the lid ensures all metallic parts are electrically conductively connected, which is essential for protection against contact voltages and for the proper operation of residual current devices.

Compatibility and accessories

For secure connection of duct sections, joint connectors of type LST... or LSTA... are required and must be ordered separately for each joint. These connectors ensure an electrically conductive and mechanically stable connection between duct sections.

Mounting and installation

Installation is carried out by securing the duct to the substrate using the single-row perforation in the base. The 250 mm spacing allows for even distribution of mounting points. The lid is secured by snapping it into place, simultaneously establishing the electrical connection and mechanical closure. Routing typically occurs along walls, ceilings, or floor plates, adhering to electrical installation guidelines.
