WIELAND PREFAB® - THE INNOVATION BEHIND
THE WORLD'S FIRST FOR MODULAR CONSTRUCTION
The two connector systems gesis® and RST® from Wieland PREFAB® are the only ones that may be installed in areas that are subsequently no longer accessible. Wieland PREFAB® is the only system that meets the requirements for factory installation in serially manufactured components and modules. Complimenting all this are ready-to-plug-in pre-installed distributors, industrially manufactured infrastructure for power supply and building control, as well as sockets and control points.
SOLUTIONS FOR FACTORY INTEGRATION
IN WET CONSTRUCTION
With the industrially prefabricated components of the Wieland PREFAB® system, it is possible to shift the complex electrical installation work from the construction site to the prefabricating factory, thereby significantly increasing the degree of integration. The electrical installation is integrated into the prefabricated components in advance so that they can be delivered to the construction site ready for connection. This speeds up workflows and considerably reduces costs.
WIELAND PREFAB® SYSTEM CABLING IN CONCRETE CONSTRUCTION
Until now, it was not possible to install the electrical installation in precast concrete elements at the factory. Either empty conduits or cable shafts were used here. For electrical branches, additional junction boxes also had to be installed, conventionally wired, and subsequently resealed.
Things are easier and more efficient with Wieland PREFAB®: The moisture-protected RST® round connector system with IP69 protection can be cast with concrete directly in the factory production process as a pluggable, pre-assembled installation with supply cable and connection and distribution pieces. This means that the individual concrete elements only have to be connected to each other later with plug & play.
Wieland Electric has proven the suitability for this application with special service life tests and suitability tests and has had them confirmed by a neutral body.

SOLUTIONS FOR
FACTORY INTEGRATION IN DRY CONSTRUCTION
With the industrially prefabricated components of the Wieland PREFAB® system, it is possible to shift the complex electrical installation work from the construction site to the prefabricating factory, thereby significantly increasing the degree of integration. The electrical installation is integrated into the prefabricated components in advance so that they can be delivered to the construction site ready for connection. This speeds up workflows and considerably reduces costs.
PREFAB SYSTEM CABLING IN MODULAR WOOD AND STEEL CONSTRUCTIONS
Until now, it was costly and required skilled workers to incorporate the electrical installation during the actual production of modular construction elements and room modules. The use of pluggable solutions in areas that were no longer accessible was not permitted. Therefore, empty conduits or cable ducts were used. In this case, the subsequent complex electrical installation was often the bottleneck on the construction site, preventing rapid construction progress.
With Wieland PREFAB®, there is now a perfect solution for the factory integration of the electrical installation in the manufacturing process of modules and construction elements made of wood and steel. This applies to all serial construction methods such as room module construction, frame construction, modular cell construction, and container construction as well as to prefabricated houses.
For the GST18® connector system from the gesis® product family, which can be used in all dry construction methods, Wieland has now received certification for maintenance-free plug connections following extensive tests and inspections. This certificate of suitability, which has also been confirmed by a neutral body, now enables the use of pluggable pre-installation in construction elements and room modules – safely and quickly. Only a few electrical installation tasks then need to be carried out on the construction site – simply with plug & play.

SOLUTIONS FOR ON-SITE INSTALLATION
The shortest possible construction time! This is one of the most important arguments in favor of modular construction. Even if the industrially manufactured construction elements and modules do not yet include an electrical installation, the pluggable Wieland PREFAB® system can be used to significantly reduce the labor time for the electrical trade on the construction site. Note: This requires timely coordination with Wieland regarding the necessary installation routes and cable routing ducts.
WIELAND PREFAB® SYSTEM COMPONENTS FOR FAST AND EFFICIENT INSTALLATION
ON THE CONSTRUCTION SITE
The reliable GST18®, GST15, and RST® connector systems have been proven to save up to 70% of the installation time. The Wieland PREFAB® system components are delivered to the construction site in the style of a modular system and are laid and plugged together there in the installation ducts and areas provided for this purpose – simply plug & play.
The amount of effort involved can be reduced even further with highly integrated installation units such as the new aluminum wall profiles, which are already equipped at the factory with all the necessary electrical components such as sockets and control points.
These can be flush-mounted, for example, as complete units in niches provided for this purpose in precast concrete elements. The ready-to-plug Wieland PREFAB® installation units minimize the installation effort and become design elements for the room design.
We deliver the pre-assembled installation units to the construction site ready for installation. The entire installation comprises connectors, cable assemblies, distribution elements, and device connectors. Circuits or applications can also be easily distinguished visually with our mechanically coded and color-coded connectors. This makes mismating impossible and installation safe and easy.

THE INNOVATION BEHIND – WIELAND PREFAB®
INDUSTRIAL
PRE-INSTALLATION
PRE-INSTALLED
SYSTEM DISTRIBUTORS
The starting point for an electrical installation is always an electrical (sub-)distributor with the necessary protective devices and fuses. In the Wieland PREFAB® system, this distributor is pre-installed by Wieland ready to plug in.
Depending on the control system selected, it is also equipped with the necessary electronic components, whether for a KNX bus system or also for powerline technology, which is especially suitable for Wieland PREFAB® applications.
PLUGGABLE
ELECTRICAL INFRASTRUCTURE
With our gesis® (IP40) and RST® (IP67 and higher) connector systems you create clear topologies for the low-voltage network and building control (e.g. via KNX bus system or alternatively via powerline). Our coded connectors ensure fast and safe electrical installation.
PRE-INSTALLED
SOCKETS & CONTROL POINTS
Sockets, switches, and other control points are also pre-installed ready to plug in – they fit into the installation sockets prescribed for the construction method and building standards. They are also prepared with the technology required for building control, e.g. KNX or powerline chips.
PRE-INSTALLED
INSTALLATION PROFILES
In a highly integrated model, the sockets and control points are even available factory-fitted in a pre-installed installation column made of aluminum that is completely ready to plug in. This installation unit can be flush-mounted in prepared wall niches, and its clear design makes it a design element for modern rooms.

DIGITAL SUPPORT
FROM PLANNING TO PRODUCTION
FROM THE CONCEPT
TO PRODUCTION PLANNING
Right from the beginning of the partnership, i.e. from the first customer-specific cabling diagram to a 3D plan of the pluggable Wieland PREFAB® system, the joint process is supported digitally.
With the BSC (Building Solutions Configurator), it is possible to obtain an initial overview of the Wieland PREFAB® schematic with just a few clicks – adapted to the customer’s construction method and process. Starting from this basic concept, the Wieland PREFAB® tools can be augmented with planning data step by step all the way through to concrete plans, which are executed with the 3D planning tool BSD (Building Solutions Designer).
INNOVATIVE PLANNING TOOLS
FOR ELECTRICAL INSTALLATION
The BSD also offers the possibility of 3D data exchange with common BIM planning software, making it possible for the first time to integrate pluggable electrical installation cabling into a holistic building design. For our customers, this creates the basis for production planning, including the electrical installation, in the factory.
The generation of customer-specific parts lists, a cost calculation, and features such as current load calculations are further useful functions of the digital Wieland PREFAB® tool support.
ANDREAS FENN,
PRODUCTMANAGER
"Cost, time constraints, and a shortage of skilled labor are forcing us to push ahead with the industrial construction of all types of buildings. This can only be done together in interdisciplinary teams. Let’s tackle this together."
