The LFG 40X40 ALPIN cable routing duct from GGK is a PVC-based system for structured installation of electrical cables on walls and ceilings. The product consists of a lower and an upper part, which connect fully overlapping, creating a closed, stable duct structure. The single-row bottom perforation in the lower part enables secure fastening to substrates using appropriate mounting accessories. The dimensions are 40 mm in height and 40 mm in width, making it suitable for use in standard installations. The colour is alpine white, a light, neutral shade that blends well in most indoor environments. The material is rigid PVC, which is UV-stabilised and flame-retardant, ensuring high resistance to external influences and improved fire behaviour. The product is manufactured in accordance with DIN EN 50085-2-1, which defines requirements for cable routing ducts for the installation of electrical cables.

Applications

The duct is intended for the installation of electrical cables in indoor environments, particularly on walls and ceilings. It is suitable for use in residential and commercial buildings where orderly and aesthetically pleasing cable routing is required. Installation typically occurs during new construction or renovation projects where structured cabling is necessary. The material properties and compliance with standards also make it suitable for applications requiring a certain level of mechanical strength and weather resistance, for example in lightly exposed indoor areas.

Functions and Equipment in Detail

The system consists of two parts: the lower part with bottom perforation and the upper part, which fits over the lower part. The overlapping connection ensures a stable and tight seal, providing mechanical stability and a certain level of protection against dust and moisture. The single-row bottom perforation in the lower part allows flexible fastening to various substrates, with the exact fastening method depending on the specific substrate. The alpine white colour ensures discreet integration into the environment. The material properties – rigid, UV-stabilised, and flame-retardant PVC – ensure long service life and high resistance to mechanical stress and environmental influences.

Technology Explained Simply

The duct is made of rigid PVC, a plastic known for its mechanical strength, resistance to UV radiation, and flame-retardant properties. UV stabilisation prevents discolouration or material degradation due to sunlight, which is particularly important for installations in bright or sunlit rooms. The flame-retardant property reduces the risk of rapid flame spread in case of fire. The DIN EN 50085-2-1 standard sets requirements for mechanical strength, electrical insulation, and fire behaviour of cable routing ducts. The overlapping construction of the duct ensures that the two parts are securely connected, resulting in a stable and tight structure.

Compatibility and Accessories

The duct is designed for the installation of electrical cables and can be combined with other components of the LFG system, such as mounting accessories, junction boxes, or end caps. The exact compatibility with accessories depends on the specific product series, with article number 11029 serving as the base for connecting with suitable accessories. The use of accessories is optional and depends on the specific requirements of the installation. The standard length is 2 metres, with special lengths up to 7.50 metres available, allowing flexible adaptation to different installation conditions.

Installation and Mounting

Installation is carried out in two steps: first, the lower part is mounted to the wall or ceiling, using the single-row bottom perforation for fastening with appropriate mounting accessories. Then, the upper part is placed over the lower part and locked in place. The overlapping construction ensures that the upper part sits securely and provides a tight seal. Installation does not require special tools, but professional execution is required, particularly regarding sound and fire protection measures, which must be observed separately.

Operational Advantages

The duct provides structured and aesthetically pleasing cable routing, which facilitates maintenance and inspection of cables. The stable construction ensures long service life and high mechanical strength. The flame-retardant and UV-stabilised properties of the material increase safety and durability of the product. The standard length of 2 metres enables efficient installation, while the availability of longer sections allows adaptation to larger installations. The single-row bottom perforation offers flexibility in fastening to various substrates.

Sound and Fire Protection

This means that during installation, special requirements regarding sound insulation or fire behaviour of the entire installation must be considered. The duct itself meets the requirements of DIN EN 50085-2-1, which defines basic requirements for fire behaviour, but additional measures are required depending on the building class and usage. These measures are the responsibility of the installer and must be implemented in accordance with applicable building and electrical installation regulations.
