A thermoplastic-sheathed cable (TPS) may comprise a toughened outer sheath of polyvinyl chloride (PVC) thermoplastic, covering one or more individual annealed copper conductors, themselves insulated with PVC. This type of wiring may be used for residential and light commercial construction. The flat version of the cable, with two insulated conductors and an uninsulated earth conductor (all within the outer sheath), is referred to as twin and earth.
Each current carrying conductor may be insulated by an individual thermoplastic sheath, colored to indicate the purpose of the conductor concerned. The protective ground conductor may also be covered with green/yellow (or green only) insulation, although, in some countries, this conductor may be left as bare copper. With cables where the current carrying conductors are of a large Cross Sectional Area (CSA), the protective ground conductor may be smaller, with a lower continuous current carrying capacity. The conductors used may be solid in cross section or multi-stranded.
The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate various embodiments of the present disclosure. In the drawings:
A cable with a conductor assembly separator may be provided. The cable may comprise an assembly, a jacket, and a conductor assembly separator comprising an interweave assembly separator. The assembly may comprise a first conductor, a second conductor, and a ground. The interweave assembly separator may be disposed between the first conductor and the ground, the second conductor and the ground, a first side of the assembly and the jacket, and a second side of the assembly and the jacket.
Both the foregoing overview and the following example embodiments are examples and explanatory only, and should not be considered to restrict the disclosure's scope, as described and claimed. Further, features and/or variations may be provided in addition to those set forth herein. For example, embodiments of the disclosure may be directed to various feature combinations and sub-combinations described in the example embodiments.
