The power loss from a four-metre-long VAMOCON 1250 switchgear assembly is reduced by around 1,200 kWh per year. This corresponds to the annual electricity consumed by a single-person household. Over a 30-year period of use, up to 12,000 euros in energy costs and up to 14 tonnes of CO2 can be saved.
Less is more and more is less – how can that be?
We’re constantly looking for innovative solutions that help to reduce greenhouse gas emissions. This exemplifies our ecologically responsible approach. We’re committed to conserving resources and a sustainable energy supply. This is particularly evident in our new and innovative VAMOCON 1250 switchgear assembly concept. This is our green technology carrier, our guiding star in ecological and sustainable power distribution. All future developments will follow this.
How did we achieve this?
Well, we developed VAMOCON 1250 exactly to meet the requirements and minimised materials where they are not needed for safe operation – this saves resources and reduces the weight. At the same time, however, we’ve made some copper bars larger – which saves energy. Because the power loss is reduced by up to 20%. And because the assembly is not constantly operating at the power limit, it lasts longer – which promotes sustainability.
And what does that do for you?
Of course, despite all the green thinking, we know that auditors also make decisions. That’s why we’ll show you an example of how you can also convince the bean counters – provided, of course, that they also want to think in the long term and are interested in the TCO principle, i.e. are receptive to the Total Cost of Ownership approach.
Lower power loss leads to lower temperatures in the switchgear assembly and noticeably extends the service life of the switchgear and electronics installed in it. Switchgear assemblies can thus be operated more sustainably and save CO2.
For a switchgear assembly with a rated current of 1,250 A, we assume an average service life of 30 years, 2-shift operation and an industrial energy price of 18.55 Ct/kWh. The additional cost of copper due to the larger cross-section compared with a conventional main busbar is offset by a saved power loss of 73 W. The energy saved in this way amounts to 295 kWh per year and metre of switchgear assembly. The larger copper cross-section therefore already pays for itself – auditors beware! – in the first year of operation. If we factor in price increases, your VAMOCON 1250 will save you 3,000 euros in energy costs and 3.5 tonnes of CO2 per metre of switchgear assembly over the period of use.
So it pays off. How long is your switchgear assembly?
* All values are per METRE of switchgear assembly. The reduced power loss from the main busbar system and the energy and CO2 savings are derived on the basis of DIN EN 61439-1 Supplement 2 (A method of temperature-rise verification of low-voltage switchgear and controlgear assemblies by calculation) and Table B.3 (Operating current and power loss of bare copper bars inside the enclosure).
