Problems solved by technology

The single fiber/thermoplastic composite core failed in these objectives.
A one fiber/thermoplastic system does not have the required physical characteristics to effectively transfer load while keeping the cable from sagging.
Secondly, a composite core comprising glass fiber and thermoplastic resin does not meet the operating temperatures required for increased ampacity, namely, between 90° C. and 240° C. or higher.
Physical properties of thermoplastic composite cores are further limited by processing methods.

Embodiment Construction

[0023] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the disclosure will fully convey the scope of the invention to those skilled in the art.

[0024] An ACCC Reinforced Cable

[0025] The present invention relates to a reinforced composite core member, wherein said member further comprises an external surface coating. In one embodiment, the composite core comprises a composite material made from a plurality of fiber reinforcements from one or more fiber types embedded in a matrix. A further embodiment of the invention uses the composite core in an aluminum conductor composite core reinforced (ACCC) cable. These ACCC cables can provide for electrical power distribution wherein el...

Abstract

This invention relates to an aluminum conductor composite core reinforced cable (ACCC) and method of manufacture. An ACCC 303 cable (300) has a composite core surrounded by an outer film (305) 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.

Description

TECHNICAL FIELD [0001] The present invention relates to an aluminum conductor composite core (ACCC) reinforced cable and method of manufacture. More particularly, the present invention relates to a cable for providing electrical power having a composite core, formed by fiber reinforcements and a matrix, surrounded by aluminum conductor wires capable of carrying increased ampacity and operating at elevated temperatures. BACKGROUND ART [0002] Attempts have been made to develop a composite core comprised of a single type of fiber and thermoplastic resin. The object was to provide an electrical transmission cable which utilizes a reinforced plastic composite core as a load bearing element in the cable and to provide a method of carrying electrical current through an electrical transmission cable which utilizes an inner reinforced plastic core. The single fiber / thermoplastic composite core failed in these objectives. A one fiber / thermoplastic system does not have the required physical ch...
