In the framework of the development of an experimental 10 T Nb{sub 3}Sn dipole coil for the LHC at CERN the effects of transverse stress on Rutherford type of Nb{sub 3}Sn cables have been investigated. For this purpose a special facility was designed and taken into operation in which the voltage-current behavior of short pieces of Nb{sub 3}Sn cables can be investigated in a background field up to 11 T and an applied stress of 300 MPa. The repulsive Lorentz force of 250 kN, generated by a set of superconducting coils, is used to impress the cable over an area of 20 {times} 42 mm{sup 2} maximum, in presence of a transport current up to 40 kA. In this paper the testing equipment is described and the first results of the observed critical current degradation of two Nb{sub 3}Sn cables are discussed.
