The present invention concerns an extension frame (1, 7, 18, 27) comprising a flange (2, 8, 19, 29, 31) and a box (3, 9, 20). The flange (2, 8, 19, 29, 31) is placed at one end of the box (3, 9, 20). A through opening is formed going through the centre of the box (3, 9, 20) and through the flange (2, 8, 19, 29, 31). A number of holes (4, 5, 10, 11, 21, 22, 33, 34) are provided going through walls of the box (3, 9, 20). Further, a system comprising two extension frames (1, 7, 18, 27) are formed. The two extension frames (1, 7, 18, 27) are placed on opposite sides of a through opening of a partition. A sealing devices (25) for cables or pipes is placed in said through opening of the partition.

Conduit through which at least one pipe or cable extends, wherein the conduit has an inner wall and is provided with a system for sealing in the conduit that is unoccupied by the at least one pipe or cable, wherein the system comprises: at least one rubber element for providing in the conduit a support-structure which is clamped-in between the inner wall and the at least one pipe or cable; and a sealant layer against the support-structure and for sealing off at least one end of the conduit between the inner wall and the at least one pipe or cable, wherein each rubber element is made of a fire-resistant vulcanized rubber of a thermally substantially non-expandable type, and wherein the sealant is made of a fire-resistant polymer which is vulcanizable at room temperature under exposure to humidity and which is also of the thermally substantially non-expandable type.

An intumescent fire resistance device for closing breaches in walls or ceilings, contains a plurality of planar carriers which are provided with an intumescent coating on at least one side. The carriers are secured to one another at least partially overlapping in an overlap region such that a strip or ring is produced the length of which is longer than the length of an individual carrier.

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. Suppressant chambers may be located in or on or engaged with junction boxes in such circuits to locally extinguish electrical fires. Fluid nozzles may be operatively engaged with sidewalls of the junction box to disburse fire suppressant therefrom.

A firestop collar (10) for sealing of openings, especially of line penetrations (12), that pass through walls (11) or ceilings has a frame (16) and a block (20) of optionally intumescent material disposed therein, and is characterized in that an intumescent inlay (22) is disposed between the block (20) and the frame (16).

A fire-protection element can be formed to accommodate a line penetration. The fire-protection element includes a substantially cylindrical housing, which has an inner side that defines a duct for at least one line and/or one pipe, where an intumescent material is sprayed directly onto at least portions of the inner side of the housing.

A firestop system for fire stopping a bus duct that passes through an opening in a marine deck or a marine bulkhead includes a boot seal wrapped around the bus duct housing. The boot seal has a top end attached to the bus duct, and a bottom end attached to the division. The boot seal is made of flexible material to allow for movement of the bus duct relative to the division due to vibration. The boot seal may be made of a thermal barrier wrap or other high-temperature insulating mat materials to allow heat generated under normal condition to escape while providing firestopping and temperature resistance under fire exposure conditions. The firestop system may also have a gasket positioned between the bus duct and the boot seal to accommodate irregularities in the outside surface of the bus duct housing.

The present disclosure provides an electrical power supply structure comprising a plurality of conductors, each conductor extending longitudinally and configured to carry high amperage electrical power, a barrier support plate comprising one or more openings for receiving the plurality of conductors, a first support structure extending longitudinally from a first side of the barrier support plate, and a second support structure extending longitudinally from a second side of the barrier support plate. 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 conductors.

A firestop collar for sealing of openings, especially of line penetrations, that pass through walls or ceilings, has a frame and a block of optionally intumescent material disposed therein, and is characterized in that the frame is of modular construction.

A sealing system for improved heat resistance in a partition wall. A frame element forms an enclosed passage, with the frame element formed by a substantially flat member arranged perpendicular to the partition wall such that a shoulder extending from the partition wall is formed wherein the space within the frame element and the second section is to be fitted with insert blocks of a fire resistant material fitted around cable, etc. for sealing therearound. An extension element encloses the shoulder of the frame element and extends the enclosed passage for the cable, etc. The extension element includes a first and a second section. The first section includes a first fastening arrangement for attaching the extension element to the shoulder. The second section is formed so that an extended enclosed passage formed by the second section is substantially equal to the enclosed passage formed by the frame element.
