Due to advances in the W7-X prototype coil development it is now possible to increase the cable diameter by 10 %. In this work an attempt is made to optimise such an improved W7-X conductor with respect to thermohydraulic considerations, to stability and to quench behaviour in case of an emergency discharge of the W7-X coil system. The thermohydraulic and stability optimisations are performed for two steady state thermal loss cases of 4 mW/m and 10 mW/m cable length. The results are optimum He mass flow of rates of 0.85 g/s and 1.25 g/s respectively.
