Abstract
Abstract So as to eliminate wind dependent displacements in control cables such as are used in container loading facilities, the weight of the cable itself is increased. To this end, braided-over lead cords are arranged in the central elements of each conductor bundle and in the corner spaces of the core. The load-carrying capacity of the carrier member is ensured by high tensile strength plastic filaments in the form of a braid and optionally in the form of corner fillings.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
120 words
In a flexible electrical control cable comprising a plurality of conductor bundles twisted on a carrier member, each conductor bundle comprising a central element with conductors twisted thereon, and a wrapping and a plastic jacket surrounding the core formed by the carrier member and the conductor bundles, the improvement comprising: (a) the carrier member comprising a plurality of lead cords in longitudinal abutting relationship, each having a braid applied thereover with a further braid of high tensile strength plastic filaments applied over said plurality of cords; (b) the central element of each conductor bundle comprising a braided-over lead cord; and (c) braided-over lead cords disposed in the outer corner spaces of the core between the conductor bundles and the wrapping.
