gesis®NRG - the flexible busbar Forward-looking, space-saving, and safe

In terms of efficiency, safety, and planning for the future, a structured electrical installation with flat cables already sets the standard. With gesis®nrg, Wieland Electric offers a TOP solution for structured and fast electrical installation. Floor boxes, lighting systems, luminaire connections, sunblind systems, building bus systems, and so on are installed systematically, transparently, and without any errors in next to no time.


The pluggable electrical installation combines in one system

  • Energy and bus system installation
  • Quick and safe setup
  • Sustainability and flexibility for the future

 

gesis®NRG – quick, easy and flexible

Robust and practical

  • Small number of different components
  • Adapters and feeds compact and robust
  • Mounting holes on all adapters
  • Contact to the flat cable by means of IDC
  • Pluggable outgoing cables with automatic interlock

Simple planning

  • A ready plan in just a few steps
  • Section quantity and length planning
  • Feeds = number of sections
  • End plates = double the number of sections
  • Adapters = quantity of e.g. floor boxes, luminaires, or consolidation points

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

Decentralized installation

  • Creates simple, future-proof structures
  • Reduces cable quantities (copper, plastics, fire load)
  • Brings sufficient energy into the areas of the building due to the three-phase cabling
  • The three-phase system reduces cable losses
  • Smaller utility rooms increases net floor area

Planning and design

Nominal cross section 2.5 or 4 mm2

We recommend the 2.5 mm² variant as standard.
We recommend the 4 mm2 variant if

  • an increased voltage drop can be expected due to long cable lengths
  • increased neutral conductor loads due to harmonic waves can be expected because of electronic loads.
    • Supplement 3 to DIN VDE 0100-520 names the applicable reduction factors.
    • The maximum reduction factor to be assumed is 0.65.
    • This means that you are always on the safe side with 4 mm² x 0.65 = 2.6 mm

Feed and fuse protection

  • We recommend the feed with round cable. You should not connect the cable directly to a distribution unit.
  • The 5/7-pole 2.5 and 4 mm² cables can be fed with up to 6 mm², while the 10 mm2 cable can be fed with up to 16 mm2.
  • The pre-fuses of the 2.5/4 mm² cable must not exceed 20 A.
  • As a rule, the cables may be 1, 3, or 4-pole with fuse protection. The same outer conductor should never be fed to several wires (neutral conductor overload).
  • Pay attention to laying methods and local regulations for fuses. The considerations must be the same as for round cables.

Fastening and laying method

  • All cables can be laid: - on plaster - in cable trays - in cable ducts - in cavity floors and raised floors. In these areas, they can be used like NYM according to VDE 0298 part 3:2006-06.
  • Fastening is recommended every 50 cm.
  • Fastening with flat cable adapters, with Wieland clamps for flat cables or with standard fastening materials such as OBO cable clamps.
