In the process, the usual test series, which range between 5000 and 20,000 cycles, were exceeded by a factor of 10: Proof of 200,000 cycles was provided for the pivoting windows on the Plärrer high-rise [...] of which the sun protection cabling runs. Since the pivoting windows only need to be opened by about 12 cm, the shearing angle is just 7.5°, which means low torsion for the low current cable integrated in
