Description
Single ReBCO coated conductor tapes must be assembled in a cable geometry to reach currents in the order of several tens of kA. For AC application, wire twist can be introduced to reduce coupling currents during magnetic field ramping but also the inter-tape contact resistance plays a crucial role. Two cable types were subjected to transverse applied alternating magnetic fields, CORC manufactured by Advanced Conductor Technologies and so called stacked tape conductors assembled at CRPP Villigen. The applied magnetic field is sinusoidal with amplitudes in the range of 5 to 400 mT and frequencies up to 0.5 Hz. In addition inter-tape contact resistances were measured under applied transverse stress. An overview of the results is presented.
