A wire harness having a bent router configured to be routed in a bent manner in a vehicle, the wire harness including: a wire; an exterior tube enclosing an outer peripheral surface of the wire; and a heat transfer tube having a rectangular tubular shape, provided between the wire and the exterior tube, and contacting an entire periphery of both the outer peripheral surface of the wire and an inner peripheral surface of the exterior tube, wherein the wire has an exposed part not covered by the heat transfer tube.

A thermal sleeve for routing and protecting elongate members and method of construction thereof are provided. The sleeve has a tubular woven wall extending along a central axis between opposite open ends with an outer reflective foil layer fixed thereto. The wall is woven with lengthwise extending warp yarns and circumferentially extending fill yarns. The fill yarns include first and second fill yarns bundled in side-by-side abutting relation as a single pick, thereby forming discrete single pick bundles in axially spaced relation from one another. The first fill yarn is provided as a standard monofilament, while the second fill yarn is provided having a low melt material melted and bonded to the abutting first fill yarn and to portions of the abutting warp yarns, wherein the spaces between the discrete bundles remain substantially free of melted material, thereby further enhancing longitudinal flexibility of the sleeve.

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.

Water mist fire protection systems and methods for the protection of data centers having a raised floor defining an interstitial space beneath the floor. The systems and methods include the location of a plurality of automatic water mist nozzles above and/or beneath the floor to generate a water mist for effectively addressing a fire in the presence of a flow of forced air ventilation through the interstitial space. The systems and methods of water mist fire protection include the interconnection of the automatic water mist nozzles to a water supply to provide for dry pipe or preaction systems and methods. Water mist fire protection of data cen-ters using fire propagating cable is also provided.

A system for holding in a conduit (7) cables and/or ducts with different diameters, comprising a plurality of rubbery or rubberlike sleeves (1) for inserting in such a conduit (7), the plurality of sleeves (1) comprising a number of units (2) of bonded sleeves (1) which are oriented parallel to each other, wherein within each unit (2) the sleeves (1) have corresponding outer dimensions, and wherein at least one unit (2) has a sleeve (1) having an inner diameter which differs from an inner diameter of a sleeve (1) of at least one other unit (2) of the number of units, wherein the number of the units (2) and the dimensions of the units (2) are such that therewith a stack of units can be made, in the stack of units (2) each sleeve (1) is also oriented parallel to any of the other sleeves (1), the stack of units having a rectangular shape of which each side is in detail shaped by the presence of a number of the sleeves (1) and of which each edge is in detail shaped by the presence of one, two or three of the sleeves (1).

The invention relates to a line feed-through (1) for feeding a line (4) through a building component, comprising one or more sealing arrangements (2) for feeding the line (4) through, wherein the one or more sealing arrangements (2) have at least two sealing structures (51) lying opposite each other, wherein at least one first of the sealing structures (51) has an arrangement of elongate fins (53) adjacent to each other, the protruding ends of which lie against a second of the sealing structures (51) and thus seal the passage region.

A firestopping apparatus including a housing defined by first and second housing members. Each housing member includes a width direction wall panel and a height direction wall panel. The width direction wall panel of the first housing member is configured to connect with the height direction wall panel of the second housing member and the width direction wall panel of the second housing member is configured to connect with the height direction wall panel of the first housing member to define an assembled housing with a through passage. Intumescent material is positioned along an inner surface of each wall panel. A compressible foam is positioned within the intumescent material and substantially closes off the through passage.

A holder for cable conduits including a first holder half connected to a second holder half, wherein the holder halves form at least one opening for holding a cable conduit, wherein the holder halves are aligned to each other by two aligning protrusions of the first holder half arranged inside two aligning recesses of the second holder half and two aligning protrusions of the second holder half arranged inside two aligning recesses of the first holder half. The aligning protrusions of each holder half are arranged symmetric to a central axis of the holder orthogonal to a connection plane between the holder halves.

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 wire harness having a bent router configured to be routed in a bent manner in a vehicle, the wire harness including: a wire; an exterior tube enclosing an outer peripheral surface of the wire; and a heat transfer tube having a rectangular tubular shape, provided between the wire and the exterior tube, and contacting an entire periphery of both the outer peripheral surface of the wire and an inner peripheral surface of the exterior tube, wherein the wire has an exposed part not covered by the heat transfer tube.
