Electrical installations in commercial buildings

Conduits for commercial and industrial areas

The requirements on electrical installations in commercial and industrial areas are at times significantly higher as compared with the construction of residential buildings. Such factors as compressive strength and resistance of conduits are of great significance, especially in industry and crafts business,

whereas circuit integrity in case of fire and prevention of hazardous smoke gas are key priorities in public areas, such as airports, railway stations or hotel facilities. FRÄNKISCHE offers electrical conduits for all kinds of mechanical stress, fire and heat resistance, or resistance to aggressive substances.



Ecological construction

Ecological construction

FRÄNKISCHE is the first provider to launch eco-balanced electrical conduits, and pledges itself to ecological sustainability in construction. The eco-balanced co2ntrol conduits by FRÄNKISCHE reduce the consumption of fossil resources by up to 60 percent and save approx. 47 percent CO2. In order to render the co2ntrol products CO2-neutral, FRÄNKISCHE plants trees in its home region that bind and continuously store the remaining CO2 of the product group.

The two corrugated plastic conduits FBY-EL-F co2ntrol and FFKUS-EM-F 105 co2ntrol are the first eco-balanced conduits for electrical installation. The Environmental Product Declaration (EPD) issued by the Institut für Bauen und Umwelt e. V. (IBU) is based on the life cycle assessment for the entire lifespan of a product according to DIN EN ISO 14040 and 14044.

Multi-media installation

Multi-media installation

The multi-media conduit conceals the tangled mess of cables around flat screens "out of sight" in the wall – simple, practical, invisible. The numerous applications of modern TVs lead to an increase in connecting cables. Surfing the internet, listening to music or watching TV to mention just a few. But where do you put the annoying cables and bulky plugs? The oval multi-media conduit presents the ideal solution. Installed hidden under screed, the conduit collects all important cables and connects them correctly to existing devices.

Cables and plugs can be inserted and replaced even years later. This way, the owner remains flexible and can take care of technical retrofitting easily and quickly at any time. For more information on the multi-media conduit, please see:

Fire protection

Fire protection

Wall or ceiling breakthroughs are called firewalls or fire stops. They must be sealed off such that fire cannot propagate into adjacent fire sections. Fire stops must feature the same fire resistance as the respective wall or ceiling. The term circuit integrity is closely connected with the term fire resistance and means that a component functions in normal use over a long period of time before it is subjected to fire. The conduit installations have been tested and approved for E30, E60 and E90 with various cable manufacturers.

Low Smoke - zero halogen

Low Smoke - zero halogen

The main danger to humans and buildings in case of fire are not the flames but the development of smoke gas.
Zero halogen low smoke conduits reduce corrosive and toxic gases to a minimum. All FRÄNKISCHE zero halogen conduits are tested 100 % zero halogen according to DIN VDE V 0604-2-100.

Standards and provisions

Standards and provisions

Conduits are considered electrical equipment and are subject to the Low Voltage Directive. All electrical equipment subject to the Low Voltage Directive must bear the CE Marking. In order to comply with the safety requirements of the Low Voltage Directive, DIN VDE and DIN product standards and erection regulations must be complied with.


Erection regulations

DIN VDE 0100-520

Low-voltage electrical installations - Part 5: Selection and erection of electrical equipment; chapter 52: Wiring systems
• This part 520 of the standards of the DIN VDE 0100 (VDE 0100) series outlines the selection and erection of wiring systems.
• Minimum requirements for the point of installation.
The standard amendment of 01 July 2013 means:
• the end of flame-propagating conduits
• the end of pliable, resilient conduits in concrete
• a new test method for zero halogen conduits

For more information on standards, please refer to our conduit guide for experts.
