Embodiment Construction

[0024] best way

[0025] The present invention relates to a collet-type fitting for engaging and terminating an ACCC reinforced cable 100 . The collet-type fitting can join the composite core 101 of the ACCC cable 100 together. In addition to joining the composite core 101 , the splice should provide an electrical connection between two or more ACCC strengthened cables 100 . Alternatively, a collet type fitting may terminate the ACCC cable. The collet-type accessory may include a collet 202 , a collet housing 204 , and at least one compressor 206 . In a further embodiment, the collet fitting 201 may also include an aluminum filter sleeve 208 and the collet joint 200 may include an aluminum shell 210 that may cover the two collet fittings 201 and the connecting device 214 . In one embodiment, the compression member 206 and the connection device 214 are formed as a single piece. However, those skilled in the art will appreciate that in other embodiments these components are ...

Abstract

This invention relates to collet-type fittings(201) for use in collet-type splices and collet-type dead ends and methods for splicing together two aluminum conductor composite core reinforced cables(ACCC) or terminating one ACCC cable. The collet-type fittings(201) comprise a collet(202) coincident with a collet housing(204) to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet(202) and the composite core. After inserting the composite core into the collet(202), a compression element(206) compresses the collet(202). The collet(202) holds the composite core with frictional forces and the collet(202) further compresses and strengthens the hold on the composite core if the composite core pulls the collet(202) further into the collet housing(204).

Description

technical field [0001] The present invention relates to apparatus and methods for splicing and terminating electrical cables. More particularly, the invention relates to fittings capable of joining two composite-core cables through a load-bearing composite core and fittings capable of terminating or occluding composite-core cables. Background technique [0002] The 2003 blackout, which affected the US, UK and France, has demonstrated the urgent need to update the global power grid. A first-rate and immediate solution is to replace the existing conductors with composite core reinforced cables. One example of a composite core strengthened cable, ACCC cable, is described in PCT Application No. PCT / US03 / 12520, which is incorporated herein by reference. Hereinafter, ACCC cables will be used to represent all composite core cables. These ACCC cables offer much increased ampacity. In some cases, ACCC cables offer 100% increased ampacity. Replacing obsolete cables with ACCC cabl...
