Extension of a transformer station near Aschaffenburg.

Task:construction of a direct coupling transformer T 412
Department:integrated and transmission networks | Energy
Business:energy supply

The continuous increase of the transmission capacity in the high voltage network and the accompanying replacement of the 220 kV voltage level by the 380 kV voltage level called for the construction of a second direct coupling transformer in a transformer station near Aschaffenburg.  After in the years 2009 and 2010 VESCON had already established a new 110 kV plant and a 380 kV switching station including a direct coupling transformer T411 on the same site, the customer commissioned VESCON again to construct a second direct coupling transformer and to set up the 380 kV and the 110 kV switch field. The customer who trusted in VESCON's experience was not disappointed: The transformer was put into operation on time in August 2012. After the successful start-up the complete dismantling of the old 220 kV plant was carried out by VESCON in January and February 2013.

Construction of a new transformer station near Brunsbüttel.

Task:construction of a 380 kV switching station for offshore wind power feed-in
Department:integrated and transmission networks | energy
Business:energy supply

In order to be able to feed the wind power produced in two offshore wind park clusters into the transmission network our customer, a renowned transmission network provider, decided to build a new 380 kV switching station on a site near Brunsbüttel in the year 2010. The customer placed the order for the construction of the entire electrotechnical part of the switching station with VESCON GmbH based in Fellbach. In many years of cooperation with this customer VESCON had already successfully handled numerous projects. On the basis of this long-term business relationship and VESCON's experience in this kind of large-scale projects the customer also trusted VESCON with the scheduling and technical coordination of the entire project.  
In three construction stages from November 2010 to April 2013 VESCON established the 380 kV switching station including a total of 14 extended switch fields on a greenfield site. After four months of planning and two years of construction activities - including pile construction works, foundation works, steel construction works and the erection of the plant building - the completely checked plant could be handed over and put into operation on time.             

Services provided by VESCON:

  • scheduling and technical coordination of the entire project
  • creation of the primary technical implementation planning
  • construction of a triple tubular busbar over 16 fields, construction of 4 line fields including catenary wire systems, 8 converter feeder panels and a transverse coupler as well as the earthing system including selection and supply of the connecting materials (HS terminals, valves, aluminium tubes, cables etc.)
  • assembly of the auxiliary installations and control/protection cabinets, laying and connection of all power and control cables as well as fibre optic cables, installation in the plant buildings, installation of the control cells and the plant lighting including selection and supply of the connection material (cables, installation material)
  • pre- and functional check of the plant and joint commissioning with the customer
