Abstract
A cable for transmitting electrical signals including an outer casing made of an electrically insulating material and at least N lines n with N≥2 and N€N which are arranged within the outer casing, wherein each line m has a total of M wires made of an electrically conductive material with M≥1 and M€N, wherein the wire m with m€[1, M], m€N, the line n with n E [1, N], n€N is surrounded by a dielectric having a predetermined value for the relative permittivity er(m,n)>1, wherein for each line n the value for the relative permittivity of the dielectrics (24. 26. 28. 30) of the wires (16, 18, 20, 22) of this line n is identical, except for deviations resulting from the manufacturing process, so that er(p·n)=er(p+q,n), where q€[1, M−p], q€Np € [1, M−1], p€N.
