Electrically powered street furniture – Bus shelters and billboards

The possibilities for outdoor advertising in public areas is increasing. Thanks to the versatile application possibilities of billboards, information of the advertising world but also information of (tourist) organisations, towns and municipalities can be displayed along access roads, shipping routes or in the town centre. In order to have the various information scrolled automatically on the board, a power supply is mandatory. On top of this, also bus shelters are used more and more for outdoor advertising purposes. Apart from scrolling information, there is often a power supply needed to light the objects.

Depending on the object and the requests, we offer a number of standard possibilities for connecting and if requested also for metering objects.

Anyone owing an electric car, motor or scooter can charge his vehicle at a charging point. Charging stations are located on strategical points, such as parking areas and parking garages, but more and more electric cars are now charged at home as well.

Depending on the charging speed of the charging point, the charging station will need a certain voltage supply and consequently needs to be protected by means of an certain amperage. Our standard connection boxes for charging stations are suitable for 400V, 50Hz and are secured up to 25A maximum.

Wind is the result of uneven warming of the earth by the sun. Wind turbines thus get a rotational movement; this movement can be converted into electricity by using generators. Wind energy is clean, which we definitely needed in order to have a sustainable energy supply in the future. The generated energy is then transported by a network administrator, which ensures it ends up in the grid.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes concerning energy gained by wind.

Solar energy is energy that is extracted from the heat and light of the sun. For example, by using solar panels. These consist out of rows of solar cells. A solar cell is made of two layers of silicon. When light shines upon a solar cell, there will be an electric current between these two layers. However, this is direct current, and alternating current is needed for the energy grid. An transducer is able to convert this direct current into alternating current. It is possible to convert about 20% of this sunlight into electricity.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes concerning energy gained by solar.

This type of energy (also called hydroelectric energy) is generated by the height difference of falling water or by the speed of running water. More than 10% of the electricity in the European Union is won by hydroelectric power. On a global level, it’s more than half. Energy is generated from hydropower by the gravity of the water. The harder the water stream, the more energy can be gained.

Depending on the required specifications, we offer a number of standard transformers for protection, measurement and revenue purposes concerning energy gained by water.

Combined heat and power (CHP) can lead to a high-energy efficiency. When electricity is generated in power plants, heat is generated and will be lost as residual heat. A CHP can reuse this residual heat for heating tap water. This method achieves a return that is twice as high as compared to separate production of electricity and heat. 

The operation of CHP is quite simple: a fuel turns a motor, which in turn turns an alternator into motion, and thus electricity can be produced. In addition, the alternator movements will also generate heat; this is cooled by a cooling liquid to prevent overheating. A heat exchanger recycles this heat from the cooling liquid and uses it to generate warm water. Additionally, the heat from the combustion gases is recovered via condensation and used for the production of hot water.
