Electricity grid deconstruction

Client:

We have completed contracts of this type for the following companies Vattenfall Europe, enviaM, Eilenburger Stadtwerke, TEAG, e.dis, Stadtwerken Chemnitz, Energiewerke Nord AG, eon Netz AG, BEWAG and BIQ

Project management TVF:

Region South East and Elektrovod TVF

Project description:

• the aluminium and steel scrap from the power and earth cables were separeted in our own facility and sold as aluminium granulate and recycled steel
• a total of 110 projects have been completed to date, including 80 involving medium and high tension sections of the overhead network
• dismantling of large transformers in situ (140 and 160 MVA, 18 inductors to date and dry and oil tranformers in power stations
• complete dismantling of 220 and 380 volt switching stations

Aims:

Economically effective and environmentally friendly deconstruction of 30, 110, 220 and 380 volt sections of the electricity network. Use of Azobe (ironwood) matting and pontoon bridges, dismantling of pylons up to 90 metres using both cranes and helicopters.
Demolition of foundations using excavators and where necessary, controlled explosions, recycling of glass and ceramic components, reusable ceramic insulators are stored, since September 2002 damaged insulators are recycled as ceramic flour using grit blasters.

Length:

As of October 2005 a total of 1.250 kilometres of grid have been dismantled, this equates to a total length of cables of 15.000 kilometres

Quantities:

Scrap cable: 11,650 tons
Pylon construction: 31,200 tons
Glass and ceramic insulators: 3,400 tons
Concrete rubbe from foundations: 73,850 tons
Renaturation with infill and mother earth: 50,000 toms
