A cable assembly for an electrical signal transmission system comprises a plurality of elongated conductors, a conductive shield surrounding each conductor, and a dielectric layer between each shield and its respective conductor. The shielded conductors are embedded in a dielectric material and the dielectric material is wrapped in a double conductive shield. Adhesive layers are located between the double shield and the dielectric material and between the two shields making up the double shield. This cable assembly results in a signal transmission apparatus which has increased immunity to the effects of external electromagnetic fields, electrostatic charge, and mechanical vibration. It is particularly useful in transmitting low level signals produced by ionization detectors used in X-ray inspection apparatus.
