In some examples, a cable guide can include a cable flange including a body, an arm extending a distance away from the body, a retention mechanism to retain the cable flange in a housing, and a first attachment mechanism. The cable guide can include a pull tab including a second attachment mechanism coupled to the first attachment mechanism, where the arm is disengaged from the housing when the cable guide is in a disengaged position, and the arm is engaged with the housing and the cable flange and the housing are to form a pathway when the cable guide is in an engaged position.

Providing electric power distribution for fracturing operations comprising receiving, at a transport, electric power from a mobile source of electricity at a first voltage level and supplying, from the transport, the electric power to a fracturing pump transport at the first voltage level using only a first, single cable connection. The first voltage level falls within a range of 1,000 V to 35 kilovolts. The transport also supplies electric power to a second transport at the first voltage level using only a second, single cable connection.

Embodiments of a liquid-cooled charging cable are described. The charging cable includes one or more electrically conductive cables having a first end and a second end. Each cable has a set of one or more cooling tubes. Each cooling tube includes an inlet and an outlet, both at the first end of the cable, a forward part in thermal contact with the cable, the forward part beginning at the inlet and extending from the first end to the second end, and a reverse part in thermal contact with the cable, the reverse part extending from the second end to the first end and ending at the outlet. The forward and reverse parts together form a continuous fluid path between the inlet and the outlet, so that a working fluid can flow through each cooling tube from the inlet through the forward part and the reverse part to the outlet.

A liquid-cooled charging system for a vehicle is configured to dissipate heat generated during charging (including fast-charging) of an electrically-powered vehicle. The liquid-cooled charging system includes a charging assembly having an interface assembly configured to support a charging plug of a charging station and an energy transfer assembly configured to electrically couple the charging station to the battery of the vehicle during charging. Components of the charging assembly and energy transfer assembly also define a fluid circuit. A coolant system of the liquid-cooled charging system is fluidly connected to the fluid circuit, allowing coolant to flow through the fluid circuit to dissipate heat from the charging assembly components during charging of the vehicle.

A line arrangement comprising an electrical line which has at least one electrical insulator and at least one electrical conductor which runs at least in some sections adjacently to the electrical insulator along a longitudinal axis of the electrical line. The line arrangement additionally has a passive heat dissipator which runs at least in some sections along the longitudinal axis and which has at least one heat-absorbing surface portion and at least one heat-emitting surface portion thermally connected to the heat-absorbing surface portion.
