March 2019 - Haarlem, The Netherlands
Hotel Van der Valk Haarlem consists of 298 hotel rooms, conference rooms, a restaurant, kitchen, bar and entrance. The hotel is being renovated and modernized inside and outside (facade) and prepared for the future. The hotel is designed in such a way that, if necessary, it can operate completely without gas and 100% on electricity. The renovation process runs until the beginning of 2020.
Commissioned by Benschop Installatietechniek, the utility team at Elektro Internationaal designs and builds various distribution panels for the electrical installation. This month the main distributor and the kitchen distributor were delivered.
Distribution panels
The 1,600A main distributor (in Prisma P by Schneider Electric) measures 2.7 m and weighs 400 kg. The 800A (KA / KL-C) sub-distributor of 3.2 meters was built in the Prisma G system and weighs just under 800 kg. The kitchen panel will provide the restaurant and the equipment there with the necessary power.
Busbar
STbenelux, expertise partner of Elektro Internationaal, provides advice, delivery and implementation of various busbar connections between the transformer from the utility company to the main switch and distribution box and from there to the floor distributor, the restaurant distributor and the future solar panel distributor. The rail (by Schneider Electric) have an IP-55 value and a combined weight of 1,500 kg. The system bridges a total distance of 151 meters and consists of the following parts:
Power supply to Main Distributor1 (MD1): 1,600A / 16 meters
From MD1 to MD General 800A / 8 meters
From MD1 to Restaurant 800A / 7 meters
From MD1 to solar distributor on roof 630A / 80 meters
From MD General to floors 630A / 40 meter
Technical match
Due to the close cooperation between Elektro Internationaal and STbenelux, the connections for the busbar system are ready made in the panel builder’s workshop. The technical match of components speeds up the on-site installation.
Phased installation process
The construction of a busbar system in a renovation project such as this has a higher degree of difficulty, since the new part is being built while demolition is in full swing. This means that the installation process is carried out in phases, which entails that the open ends of the rail are covered time and time again to keep them as dust-free as possible. The flexibility of building with busbar offers a clear advantage in a renovation project such as this.
