Abstract:
A storage device for payout of a data transmission line comprising a spool and a data transmission line wound in a plurality of layers on said spool from an inner region to an outer region to form a package of said layers, said data transmission line being wound in said layers at a defined tensile stress, said defined tensile stress at which said layers are wound being less than a maximum stress Fmax which is a function of the diameter of the transmission line, the diameter of said spool, the modulus of elasticity of said transmission line and the number of layers of said layers in said package in order to prevent creep between adjacent layers and provide stability of said layers, wherein each winding layer is wound at said defined tensile stress to exert a pressure on the winding layer thereunder of less than 0.6 N/mm2 at least in the inner region of the package.
