A connection arrangement for a floor power distribution system includes a hub arrangement configured to distribute electrical power and including a hub housing and an electrical connector, the hub housing configured to abut a floor, and an adapter configured to engage the hub housing of the hub arrangement and configured to abut the floor, wherein at least a portion of the adapter is cantilevered over at least a portion of the hub housing, wherein the portion of the adapter that is cantilevered over the portion of the hub housing is vertically aligned with the electrical connector of the hub arrangement.

A device is used to sever an electrical power cable for the transmission of high voltage. The cable has an insulation sheath, a screening layer and a conductive layer. The device includes a first frame having a first cutting blade mounted thereon, a second frame, and a measuring device mounted on the second frame. The first cutting blade is movable relative to the measuring device. The measuring device is capable of measuring an electrical load on the electrical power cable and capable of terminating the severing of the electrical power cable. A method of using the device is also provided.

Termination assembly for three-phase high voltage submarine cable(s) (1a-c), has an open enclosure (10) with at least two cable lead-in (3a-c) located at one end (16) of the enclosure, at least six termination units (21-29) within the enclosure for receiving three phase conductors per cable, respectively.

In order to enable switching control over power-feeding paths even in the event of a ground fault or an open fault in a power-feeding path, the submarine branching unit is provided with: a switching circuit which switches multiple power-feeding paths formed among a first through a third power-receiving ports; a control circuit which receives power from a power-feeding path formed between the first power-receiving port and the second power-receiving port and controls the switching circuit; and a connection circuit which connects the control circuit between the third power-receiving port and a sea-earth when no power is supplied to the control circuit from the power-feeding path formed between the first power-receiving port and the second power-receiving port.

The present disclosure relates to method for underground installation of a pre-ducted optical fiber cable assembly. The method includes a first step of drilling a first pilot bore from a second manhole to a first manhole. In addition, the method includes a second step of pulling the pre-ducted optical fiber cable assembly. Further, the method includes a third step of drilling a second pilot bore from a third manhole to the second manhole. Furthermore, the method includes a fourth step of pulling the pre-ducted optical fiber cable assembly from the second manhole to the third manhole. Moreover, the method of underground installation of the pre-ducted optical fiber cable assembly eliminates the need for blowing the pre-ducted optical fiber cable assembly with a cable blowing machine.

A system for preventing damage to a power cable for electric power transmission to and from and within a floating offshore wind power plant using non-redundant mooring, after failure of a main loadbearing mooring element is described, comprising at least one power cable safety line having the following properties: It is connected to the same two wind turbines as the power cable it is designed to protect. It has an effective length shorter than the power cable it is designed to protect. It has an effective length longer than what is needed to remain largely unstressed when the distance between the floating wind turbines with intact mooring systems is at its maximum. It has a breaking strength being a predetermined fraction of the strength, which the main loadbearing mooring elements are designed for.
