This patent presents the development of Mobile Marine Charging Stations (MMCS) that will be integrated with power utility grids to serve marine transportation infrastructures and applications. MMCS will ensure sustainable and safe operation during normal and emergency conditions. This patent proposes the design of fast charging stations for marine transportation infrastructures and applications where the station would supplement the short-trips and long-trips charging processes. The energy management of the station is performed by an optimization and rule-based algorithm that controls the power flow between the fast chargers, the energy storage system and the grid terminals. The trade-off between the technical and economic benefits is implemented to optimize the size of energy storage system and the power rating of the grid connection, as well as optimize the operation of MMCS. Flywheel is utilized in the design of MMCS due to its kinetic energy storage that offers powerful features.

Shatter protection for a high voltage apparatus with a ceramic insulator includes at least one electrically insulating tube including a plurality of holes going through an envelope surface. The electrically insulating tube has a diameter such that there is a minimum distance between the tube and the ceramic insulator when arranged concentrically. A method for producing a shatter protection includes winding a first helix shape of the electrically insulating fiber composite material at a first pitch such that there is a first gap between the winding turns, and winding a second helix shape of the electrically insulating fiber composite material onto the first helix shape in the opposite direction and at a second pitch, such that there is a second gap between the winding turns. Thereby forming a first electrically insulating tube with holes formed by the first and second gap between the winding turns.

The present invention relates to a fire-protection-collar element (10) for forming a fire-protection collar (35) for closing through-passages in walls (38), ceilings and/or floors in the event of a fire. The present invention also relates to a method for forming a fire-protection collar (35) for closing through-passages in walls (38), ceilings and/or floors in the event of a fire.

The disclosure relates to an intumescent fire sleeve for a conduit, such as a pipe, a cable or a device penetrating a wall, a ceiling or a floor in a building, said fire sleeve comprising at least one layer of intumescent material and one carrier being connected to the layer of intumescent material, and said fire sleeve having a length (L) that at least corresponds to a circumference of the conduit for which it is intended, with the characteristics that at least the carrier has spring-loaded characteristics and that the carrier, in a non-applied position has the ability to coil onto itself in a spiral manner. The disclosure also relates to a coil of such intumescent fire sleeves and to a method for installation of such an intumescent fire sleeve.

The present disclosure provides an electrical power supply structure comprising a plurality of insulated pipes, each insulated pipe extending longitudinally and configured to carry high amperage electrical power, a barrier support plate comprising one or more openings for receiving the plurality of insulated pipes, the barrier support plate configured for mounting over a hole through a floor of a building, a first support structure extending longitudinally upward from an upper side of the barrier support plate, and a second support structure extending longitudinally downward from a lower side of the barrier support plate through the hole. Each of the first and second support structures comprises a longitudinally extending enclosure having a plurality of transversely extending conductor support members for supporting the plurality of insulated pipes, and the plurality of insulated pipes are grouped by phase.

A seal-off fitting for a conduit system includes a conduit body defining an inner cavity, at least one conduit port adapted to receive a conduit, and at least one threaded sealing port. The seal-off fitting further includes a threaded seal-off cover engageable with the sealing port, a first coating applied to at least a portion of the conduit body, and a second coating applied to at least of portion of the seal-off cover. At least a portion of the threads of the sealing port and at least a portion of the threads the seal-off cover remain uncoated, with the uncoated threads of the sealing port and the uncoated threads of the seal-off cover defining a flame path for flue gases exiting the conduit body.

A device for routing lines, pipes, and/or cables through a building part, contains a housing having a housing wall. The housing has an axial passage channel that is delimited by the housing wall and extends in the longitudinal direction, and has in each case an opening at opposite ends. At least two sealing arrangements are each provided in the housing interior, are designed for sealing the passage channel, and form a sealing surface. A first sealing surface has a plurality of sealing elements which are elongated, extend in a first main direction, and are adjacent to one another. A second sealing surface has a plurality of sealing elements that are elongated, extend in a second main direction, and are adjacent to one another. The first main direction and the second main direction differ from one another with respect to a transverse plane perpendicular to the longitudinal direction.

A furniture item includes a main body with an electrical device installed thereon. A power line electrically connects the electrical device to an external power source and is concealed in a power line channel formed in one or more of the walls of the main body. A switch may be connected to the main body and electrically connected to the electrical device, for controlling the electrical device. A main body door moveable from a first position to a second position may trigger the switch to enable and disable electrical connection between the external power source and the electrical device.

Disclosed is a fireproof airtight electrical box. The disclosed fireproof airtight electrical box includes a metal gang box to which is attached a sealing mechanism which will allow the gang box device to form at least a hermetic, preferably air-tight, seal within a larger structure, while at the same time being suitable for use within such a structure because of the stiffness, strength, and at least fire resistant qualities.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.
