Abstract
An electrical cable having a plurality of conductors including a grounding conductor and at least one power-carrying conductor. The plurality of conductors disposed approximately in parallel within an outer jacket such that the electrical cable has a substantially elongated horizontal cross-section.
Claims19
A method of fabricating an electrical cable, the electrical cable including a plurality of insulated conductors and a bare conductor disposed approximately in parallel within an outer jacket such that the electrical cable has an elongated horizontal cross-section, comprising:
- parallelizing the insulated conductors and the bare conductor with a first guide plate;
- wrapping the bare conductor with a filler sheath;
- surrounding the parallelized insulated conductors and the filler-wrapped bare conductor with binding;
- and
- extruding the outer jacket over the parallelized insulated and filler-wrapped bare conductors such that the electrical cable has the elongated horizontal cross-section.
A method of fabricating an electrical cable, the electrical cable including a plurality of insulated conductors and a bare conductor disposed approximately in parallel within an outer jacket such that the electrical cable has an elongated horizontal cross-section, comprising:
- parallelizing the insulated conductors and the bare conductor with a first guide plate;
- wrapping the bare conductor with a filler sheath;
- surrounding the parallelized insulated conductors and the filler-wrapped bare conductor with a filler;
- and
- extruding the outer jacket over the parallelized insulated and filler-wrapped bare conductors such that the electrical cable has the elongated horizontal cross-section.
A method of fabricating an NM-type electrical cable:
- parallelizing at least three insulated conductors and a bare conductor;
- wrapping the bare conductor with a filler;
- wrapping the parallelized insulated conductors and the filler-wrapped bare conductor with filler to produce a filler-wrapped assembly;
- and
- forming jacket around the filler-wrapped assembly to produce a generally elongated horizontal cross-section with the at least three insulated conductors and the filler-wrapped bare conductor.
