Abstract:
The different embodiments of the cable stand-off serve as a thermally inslutative protector. In one embodiment, the cable stand-off includes an elongated member defining a lumen therethrough, and a plurality of fins extending from an outer surface of the elongated member, wherein the plurality of fins includes sets of fins, each set of fins being spaced a longitudinal distance from one another and being positioned around a circumference of the elongated member. Another embodiment of the cable stand-off comprises an elongated member having a helical shape and surrounding at least a portion of a length of at least one energy transmission conduit. In yet another embodiment, a cable stand-off comprises an elongated surrounding at least a portion of a length of an energy transmission conduit, wherein the elongated member is made of a non-flammable, low particulate, flexible fiber material.
Abstract:
A shield conductor Wa comprises: a metallic pipe 20, a wire 10 to be inserted into the pipe 20, and a groove-like fitting member 22 provided in the pipe 20 as extending along the direction of axis of the wire 10, and at the same time, attached tightly to the circumference of the wire. With the inner surface of the groove-like fitting member 22 in the pipe 20 attached tightly to the circumference of the wire 10, the heat generated in the wire 10 is transmitted directly to the pipe 20, and then released to the air from the circumference of the pipe 20. This improves radiation performance of the shield conductor Wa.

Abstract:
An electrical cable is described comprising a threadlike conductor, an insulator and a sheat. The cable according to the invention is characterized in that the outer surface of said sheat has some portions standing out with respect to an average line and portions which are below it. In particular, the portions standing out with respect to an average line and the portions which are below it define a plurality of longitudinal grooves. the cable according to the invention has many advantages over conventional cables such as a greater heat-loss capability, a greater flexibility, smaller overall dimensions and lower laying friction of the cable itself.
Abstract:
An electrical charging arrangement in a motor vehicle is disclosed having a power coupling element and at least one current conductor. A cooling element is arranged on the rear side of the power coupling element facing the current conductor so that the power coupling element can be cooled from the rear side.
Abstract:
Twisted pair cables incorporated separators with cooling channels are described. A cable may include a plurality of twisted pairs of individually insulated electrical conductors, and a separator extending lengthwise along a longitudinal length of the cable may be positioned between at least two of the plurality of twisted pairs. The separator may include a flexible body configured to maintain the at least two pairs in a predetermined configuration. A first channel extending lengthwise may define a longitudinal cavity through the separator, and at least one second channel may extend from the first channel through the flexible body to an outer surface of the separator. Additionally, the cable may include a jacket formed around the plurality of twisted pairs and the separator.
Abstract:
The invention relates to a winding device (8) for an electric cable (4, 4a, 4b) including a cylindrical hub (62), perforated (622) at its surface and open (624) at at least one of its ends, the cable having at least one conductor (41, 42, 43, 44) and a sheath (45, 45a, 45b) with an outer surface having an irregular cross-section.
Abstract:
A plurality of heat conducting fins disposed on various types of electrical conductors both insulated and uninsulated, and for both high and low voltage applications such as in bus bars, disconnect and knife switches, and circuit breakers. Each of said fins includes a central opening which is slightly smaller in one dimension than the conductor on which the fins are assembled and therefore must be distorted somewhat during assembly on the conductor. The distortion in each fin develops a torsional stress in the fin which causes it to tightly grasp the conductor. In certain high voltage applications, the fin may be insulated or bent over to reduce the effective radial size of the fins in the overall conductor assembly without reducing its surface area and ability to convect heat.
Abstract:
Methods and systems for a dielectric material coated busbar are provided. In one example, a conductive material may be formed into a shape of a busbar and portions of the busbar may be selectively coated with a dielectric material which may be both electrically insulating and thermally conductive. The dielectric coated portions of the busbar may dissipate heat to a heat sink via a thermal interface material compressed on the busbar.
