FLAT CABLE SYSTEM

FLAT CABLE FOR INDOOR USE - GESIS® NRG

The gesis® NRG flat cable system combines all the advantages of a modern and decentralized electrical installation. 

SMART POWERED

gesis® NRG enables outputs to be installed and removed easily without cutting and stripping the cable. Routing is flexible and uses the minimum of space. The flat cable system thereby simplifies installation and planning, and guarantees not only pure energy distribution but also the combined distribution of energy and data (KNX, SMI, DALI) inside buildings. With gesis® NRG, Wieland presents an outstanding solution for structured and fast electrical installation. Pluggable outputs offer a smooth transition to the world of gesis® CLASSIC – with all the advantages of a pluggable electrical installation.

THE FIELDS OF APPLICATION OF THE GESIS® NRG SYSTEM 

DECENTRALIZED BUILDING AUTOMATION

With the 7-pole gesis® NRG flat cable, energy and signals can be supplied to the field with one cable. Our directly pluggable gesis® installation connector systems allow distribution to the consumer. This results in a structured installation that can easily be adapted and extended.

INFRASTRUCTURE CABLING 

The area is supplied via a smart supply by flat cable with a high core cross section. This ensures a comprehensive availability of power.

MAINS SUPPLY AND WORKSTATION SUPPLY 

The different versions of the gesis® NRG flat cables supply floor boxes with and without decentralized fuse protection. The pluggable electrical installation can also be continued inside furniture. This creates clear interfaces and provides safety.

LIGHTING SUPPLY 

Comprehensive mains and DALI signal coverage for offices means that changes or extensions can be realized without any effort.

ADVANTAGES OF FLAT CABLES

QUICK INSTALLATION WITH GESIS® NRG

With the installation of gesis® NRG products, there is no need for any cutting, baring, or stripping thanks to the use of piercing technology.

gesis® NRG MAKES PLANNING SIMPLE

With a straightforward installation and free phase selection using our adapter, your installation can be planned quickly and easily.

SIMPLE EXTENSION OF THE EXISTING INSTALLATION

The installed gesis® NRG system can be extended or moved at any time.

SMART INSTALLATION

Gesis® NRG supports a smart installation with clear structures, e.g. distinctive color coding for the cabling of the normal network and the IT network. There is also the option of decentralized infrastructure cabling.

ABSOLUTELY FLEXIBLE

The adapters for feed and tap can be freely positioned at any point along the flat cable.

QUICK, EASY, AND FLEXIBLE

ROBUST AND PRACTICAL

  • Small number of different components
  • Adapters and feeds compact and robust
  • Easy and quick installation
  • Contact to the flat cable by means of Piercing-Technology (no baring and stripping necessary)
  • Fulfillment of all the requirements of fixed installations


RESOURCE-EFFICIENT

  • Quick planning and installation
  • Reduction in cable material (copper and plastics)
  • Short connection cables for end consumers
  • Energy savings due to three-phase cabling


EASY TO COMBINE, COHESIVE SYSTEM

  • The output adapters of the gesis® NRG 5G10 system can directly feed customized and property-specific distribution boxes. These are used for fuse protection and sub-distribution.
     
  • The output adapters of the gesis® NRG 5G2.5/4 system are all designed to be directly pluggable. After leaving the flat cable, it is possible to transition directly to gesis® CLASSIC in order to run the electrical installation to all the consumers.

CONVENTIONAL VS. GESIS® NRG 

Our gesis® NRG flat cable system is impressive: not only is it flexible, it also saves resources and reduces the fire load inside the building. For supply to 18 floor tanks, as described in the following setup, use of our gesis® NRG flat cable saves up to 66% of the copper required besides reducing cable losses and the fire load.

WARNING: No compatibility between connector systems from different manufacturers

Mixed connections between Wieland GST® connectors and connectors from other manufacturers can endanger the health and safety of people, animals and property. 

Mixed connections between Wieland GST® connectors and connectors from other manufacturers can lead to the loss of the presumption of conformity according to Section 4 of the 1st ProdSV (Low Voltage Directive). Connectors from other manufacturers may not be made available or offered on the market in combination with Wieland GST® connectors or with the statement "Compatible with Wieland GST® connectors".   

Explanation:

The Wieland gesis® CLASSIC installation connector system consists of GST® connectors, GST® device connectors, GST® distribution blocks and pre-assembled variants with different cable cross-sections and different connection techniques. All GST® products are certified in accordance with the harmonised standard EN IEC 61535 and are marketed by us for the establishment of a permanently pluggable connection in electrical installation systems. 

EN IEC 61535 is a product standard and only regulates the requirements for product design; as a product standard, EN IEC 61535 does not contain any specifications for the design of connectors; i.e. unlike design standards (e.g. for the manufacture of earth contact connectors), codings and mating face can be freely selected by the manufacturers and can also be further developed within an installation connector family. This design freedom means that mechanical pluggability alone does not establish compatibility between connectors from different manufacturers.     

Accordingly, the product standard EN IEC 61535 stipulates that only installation connectors from the same manufacturer should be used for installations, as this is the only way to ensure safe power transmission over a long period of time.
