Abstract
Improved shielding members and electric cable constructions which utilize these shielding members are described. Various configurations of the shielding members can be used to enclose a single cable circuit consisting of one or more conductors in two concentric metallic shielding layers fabricated from a single shielding member which provides excellent electrical isolation for the cable circuit. Generally, the shielding members comprise an elongated ribbon of insulating material and a pair of elongated foil strips arranged in parallel relationship with the ribbon. The foil strips are bonded to opposite sides of the ribbon and each has an elongated edge generally in alignment with opposite elongated edges of the ribbon. The selective use of layers of heat sensitive sealing material for sealing the shielding layers protects the cable circuits from moisture.
