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).
Abstract:

The pole comprises one or more panels having a first side edge with a first coupling device and second side edge with a second coupling device, the first and second coupling devices for mating the panels. In various embodiments, the panels further comprise an inner skin, an outer skin and a corrugated middle composite cross brace section that couples the inner skin to the outer skin, wherein the middle composite brace sections may further comprise any plurality of angles between -180° to +180° with respect to the inner and outer skins. Alternatively, the panels comprise an inner skin, an outer skin and a plurality of longitudinally extending composite tubes spanning the space between the inner and outer skins.
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 surrounded by an outer film (305) and at least one layer of aluminum conductor (306).

Abstract:
The present invention relates to z-direction reinforced composite panels (100) which include a core (104) as well as facing layers (102, 106) and z-direction reinforcement (108) disposed therein. The panels (100) can lie in multiple planes thereby having multiple sides (110, 112, 114, 116). The panels (100) are arranged together to form a pole assembly.
Abstract:
The present invention embeds a Fabry-Perot Optical sensing device (102) in a composite cable (101) or installs it with the splices (104) or dead ends (106) to measure a plurality of physical characteristics in a composite cable (101) and accompanying splices and dead ends. The present invention may place one or more of the sensors (102) into different parts of the cable (101) or may place one or more sensors (102) along one stretch of cable (101). The present invention may use these sensors (102) to measure strain, temperature, pressure or other physical characteristics. The present invention describes methods of employing these devices in a power grid that uses composite cables (101).
Abstract:
The present invention relates to z-direction reinforced panels (100) and more particularly, sytems and methods for fabricating such panels. Panels comprising one or more planes defined by sides (110, 112, 114, 116) are formed by stitching to form a reinforced perform and then pultruded in a continuous process.
