[en] WENDELSTEIN 7-X (W7-X) aims to demonstrate that the helical advanced stellarator concept is a viable option for a continuously working fusion reactor with global energy and particle transport being similar to that of tokamaks. The necessary twist of the plasma column is produced by 50 non-planar coils only. Additional 20 coils allow to vary iota between 4/5 and 6/5. Superconducting coils, a continuously working ECR heating system and a divertor designed to remove the full heat load allow steady-state operation. The plasma temperature and density can be increased by ICR heating resp. NBI to reach β-values of up to 5 %, densities of up to 3x10²⁰ m^-3 , and a fusion product n(0)Tτ of up to 3x10²⁰ m^-3 KeVs. Based on the results of the development of an advanced conductor, of a prototype of an original-sized superconducting non-planar coil and of an 1/8 sector of the stellarator the machine had been designed in detail and all major components are being manufactured by industry. This paper reports the technical status of the machine and highlights special aspects of the construction.
