Powerful electric current pulses through the mains of the aluminum smelter in Straumsvik in Iceland. The induction currents can heat up the reinforcing steel up to 400°C. An efficient alternative to steel is the ComBAR from Schöck.

Powerful electric current pulses through the mains of the aluminum smelter in Straumsvik, Iceland. This makes the installation of the reinforced-concrete cable combs risky, because the induction currents can heat up the reinforcing steel up to 400°C. The concrete bursts and becomes unstable. This cannot happen with the ComBAR from Schöck. Electromagnetic fields leave the non-conductive glassfiber reinforcement cold.

Electric power in Iceland – generated by hydro power and geothermal springs - is in abundance and inexpensive. The aluminum industry is its biggest customer. With it it produces the...
