Abstract
A multi-conductor transmission cable which includes a plurality of parallel conductors each of which may be insulated with a relatively low loss, high velocity of propagation material. The insulations surrounding an adjacent conductor pair may be joined by a homogeneous integrally formed EMF window web formed of the same material as the insulations. The thickness and length of the window webs are selected to control the electromagnetic interference between the conductor pair, as well as the impedance and capacitance. Individual, uninsulated screen conductors may be positioned between adjacent conductor pairs to further minimize EMF interference. The insulated conductors, their EMF window webs, and the uninsulated screen conductors may be encapsulated by either upper and lower layers of laminated insulation or by an extruded outer layer formed of a material having a velocity of propagation different from the conductors' insulations. The thickness of the outer laminated layers or extruded layer may also be varied between adjacent insulated conductors to further control EMF interference therebetween.
