Abstract
This invention relates to an aluminum conductor composite core reinforced cable (ACCC) and method of manufacture. An ACCC cable (300) has a composite core and at least one layer of aluminum conductor (306). The composite core (303) comprises a plurality of fibers from at least one fiber type in one or more matrix materials. According to the invention, unique processing techniques such a B-Staging and/or film-coating techniques can be used to increase production rates from a few feet per minute to sixty or more feet per minute.
Claims54
A composite core for an electrical cable, the composite core comprising:
- a plurality of substantially continuous reinforcing fibers of a first type embedded in a resin;
- and
- a layer surrounding the reinforcing fibers of a first type, the layer comprising fibers of a second type that are different than the first type fibers, the second type fibers of the layer being laid at least a first angle relative to a longitudinal axis of the composite core, and
- wherein the composite core is adapted for use as a strength member in an electrical distribution and transmission cable.
A composite core for an electrical cable, the composite core comprising:
- a plurality of substantially continuous reinforcing carbon fibers embedded in a resin;
- and
- a layer surrounding and insulating the reinforcing carbon fibers, the surrounding layer comprising glass fibers wherein the glass fibers are laid at least a first angle relative to a longitudinal axis of the composite core,
- wherein the composite core is adapted for use as a strength member in an electrical distribution and transmission cable.
An electrical transmission and distribution cable, comprising:
- a composite core strength member, the strength member comprising:
- a plurality of substantially continuous reinforcing fibers of a first type embedded in a resin;
- and
- a layer surrounding the reinforcing fibers of a first type, the surrounding layer comprising fibers of a second type that are different than the first type fibers, the second type fibers of the surrounding layer being laid at least a first angle relative to a longitudinal axis of the composite core, and
- at least one layer of conductor surrounding the strength member.
An electrical transmission and distribution cable, comprising:
- a composite core strength member, the strength member comprising:
- a plurality of substantially continuous reinforcing carbon fibers embedded in a resin;
- and
- an layer surrounding and insulating the reinforcing carbon fibers, the surrounding layer comprising glass fibers wherein the glass fibers are laid at least a first angle relative to a longitudinal axis of the composite core, and
- at least one layer of aluminum conductor strands surrounding the strength member, wherein the composite core has a modulus of elasticity within the range of about 7 Msi to about 37 Msi and a tensile strength above 160 Ksi.
