CABLE WITH MULTIPLE CONDUCTORS EACH HAVING A CONCENTRIC INSULATION LAYER

摘要

An electrical transmission cable has at least two wires joined in side-by-side relationship by a web. Each wire has a central conductor surrounded by a single layer of insulation that has an outer surface. A majority of the outer surface of the insulation layer is concentric with the conductor. The web is attached at first and second ends to the outer layers of the insulation of the first and second wires. The web has a neck located intermediate its first and second ends with the neck defining the point of least cross-sectional area of the web. Separation of one wire from the other will cause the web to break at the neck, thereby preventing damage to the insulation layer. Chordal segments of the insulation layer may be used to minimize the width of a multi-wire cable.

1. An electrical transmission cable, comprising:
first and second wires each having a central conductor and a single insulation layer having an outer surface which defines a circular cross-section, a majority the outer surface of the insulation layer being concentric with the central conductor; and a web having a first end connected to the outer surface of the first wire's insulation layer and a second end connected to the outer surface of the second wire's insulation layer.
