1. Application / Description
This tunnel project approx. 30 m below of London’s city centre was the longest in the history of Vetter. For reasons of size of the access shafts all cables had be inserted by both ends and transported in the underground up to 10 km. Due to cable lengths of up to 1000 m the weight to be transported arose up to 40 tons. This tunnel project approx. 30 m below of London’s city centre was the longest in the history of Vetter.
