Provided is an electric cable for a wind turbine, wherein the electric cable includes at least one cooling element) to cool the electric cable, wherein the cooling element protrudes from the surface of the electric cable.

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.

Disclosed are example embodiments of a switching terminal that can be rotated with minimal parts. The switching terminal can include: an inner portion configured to be securely or loosely attached to an external conductor element; and an outer portion configured to be rotatably affixed to the inner portion when then inner portion is loosely attached to the external conductor and to be tightly affixed to the inner portion when then inner portion is tightly attached to the external conductor.

An electric cable for supplying power to aircrafts, rail vehicles, motor vehicles, ships or other devices is a single or multi-conductor cable and includes one or more current conductors with at least one insulation. A single or multi-layer outer casing is distributed over the periphery and is associated with the outwardly protruding reinforcing elements. The reinforcing elements are in the form of cooling ribs protruding preferably over the entire periphery of the cable and enable the surface of the cable to be increased and as a result, improve heat dissipation. The projecting reinforcing elements considerably reduce the risk of burning when the current conductors heat up and also protect the cable against abrasion. The invention also relates to a plug for the electric cable.

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.

A heat dissipation module and a projection apparatus are provided. The heat dissipation module dissipates the heat generated by a plurality of heating elements, includes a heat pipe, a heat dissipation plate, a first and a second heat dissipation fins. The heat pipe includes a first portion of the heat pipe passes through the first heat dissipation fin and a second portion of the heat pipe passes through the second heat dissipation fin and a third portion connected with the first and the second portions. The third portion of the heat pipe and the heating elements are connected to the heat dissipation plate. The heat generated by the heating elements is dissipated by the heat dissipation plate, the first and the second heat dissipation fins through thermal conduction method and thermal convection method. The invention saves accommodating space in the projection apparatus and has an efficient heat dissipation effect.

A power connector includes a housing having a terminal channel holding a terminal. The terminal includes a mating pin at a front of the terminal and a cable connector at a rear of the terminal. The mating pin is positioned in the terminal channel for mating with a charging connector. The power connector includes a power cable including a conductor terminated to the cable connector at the rear of the terminal. The power connector includes a cable heat exchanger thermally coupled to the conductor of the power cable. The cable heat exchanger includes a coolant channel for coolant flow through the cable heat exchanger for actively cooling the conductor of the power cable. A thermally conductive separator electrically isolates the cable heat exchanger from the conductor of the power cable.

Fluidic channels and pumps for active cooling of cables are described. One cable assembly includes a conductor having a length between a first end of the cable and a second end of the cable and a fluidic channel structure that at least partially surrounds the conductor along the length of the conductor. A first pump connector is coupled to a first end of the fluidic channel structure and a second pump connector is coupled to a second end of the fluidic channel structure. Motion of liquid metal, when pumped through the fluidic channel structure, distributes heat away from the conductor.
