A heavy-duty road transport of a transformer weighing almost 300 tonnes might not be daily routine for a transmission system operator (TSO), but it is nevertheless part of the operational business. For the public, such a transport can be quite a sensation, as witnessed by TSCNET shareholder TransnetBW, one of the four German TSOs. Thousands of intrigued spectators lined the streets to watch the event: a slowly moving road train with 32 axes, a length of 75 metres, and a total weight of more than 530 tonnes.
It took three nights to complete the 40 kilometres from Tübingen in the German federal state of Baden-Württemberg to TransnetBW’s Engstlatt substation near Balingen at the foot of the Swabian Jura. At three o’clock in the morning of 30 May, the 380kV transformer finally reached its destination. Here, it will substitute the old transformer to improve the operational performance of the substation, which is the central hub for the power supply in the Zollernalb area.
Until well after midnight, the onlookers in the villages on the transport route marvelled the spectacle of the carefully navigating transport unit. Alexander Schilling, spokesperson of TransnetBW, commented on the public interest: “That really had the character of a funfair. Simply stunning. I have never experienced anything like that.”
