ELECTRICAL APPARATUS
Electrical Apparatus (100) includes an end of a cable (500) being connected to a transmission optimizer (20), and the cable (500) conducts a current in the range of 0.01 mA to 800 A at a voltage ranges from 12V to 140 KV for the transmission of power, data and signal. The cable (500) includes at least one insulated conductor core formed with an innermost insulating layer (220) disposing around the outside of a conducting layer (210) having carbon fibre or graphite fibre as a conductor core (210). The cable (500) includes a single insulated conductor core to form a single-core cable (300). A reinforcement layer (250) and or a shielding layer (230), (232) being provided around the outside of the innermost insulating layer (220). An outer insulating layer (240) disposes around the outside of the reinforcement layer (250) and the shielding layer. The cable (500) includes multiple numbers of single insulated conductor core to form a multi-core cable (400). A certain number of the multiple numbers can be loaded together to form as a group by a wrapping layer (260) with a screen material in tape form and or a binder tape. An inner jacketing (225) is provided around the outside of the wrapping layer (260). A shielding layer (230) (232) and or an reinforcement layer (250) being provided in between the inner jacketing (225) and the outer jacketing (240).
Unified Power and Data Cable
In one embodiment, a cable includes a data transmission path disposed about an axial center of the cable and a power transmission path sheathing the data transmission path. The power transmission path includes a power layer and a ground layer, where the power transmission path is characterized by a distributed impedance having at least one frequency dependent impedance characteristic. In some implementations, ground layer shields the data transmission path from electromagnetic interference. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by a capacitance value that satisfies a capacitance criterion at frequencies above a first frequency level. In some implementations, the frequency dependent impedance characteristic of the power transmission path is characterized by an inductance value that satisfies a first inductance criterion at frequencies above a first frequency level.
Composite core for electrical transmission cables
A composite core for use in electrical cables, such as high voltage transmission cables is provided. The composite core contains at least one rod that includes a continuous fiber component surrounded by a capping layer. The continuous fiber component is formed from a plurality of unidirectionally aligned fiber rovings embedded within a thermoplastic polymer matrix. The present inventors have discovered that the degree to which the rovings are impregnated with the thermoplastic polymer matrix can be significantly improved through selective control over the impregnation process, and also through control over the degree of compression imparted to the rovings during formation and shaping of the rod, as well as the calibration of the final rod geometry. Such a well impregnated rod has a very small void fraction, which leads to excellent strength properties. Notably, the desired strength properties may be achieved without the need for different fiber types in the rod.

Energy efficient conductors with reduced thermal knee points and the method of manufacture thereof
The present invention relates to electrical conductors for electrical transmission and distribution with pre-stress conditioning of the strength member so that the conductive materials of aluminum, aluminum alloys, copper, copper alloys, or copper micro-alloys are mostly tension free or under compressive stress in the conductor, while the strength member is under tensile stress prior to conductor stringing, resulting in a lower thermal knee point in the conductor.
