A firestop collar (10) for sealing of an opening, especially of a line penetration (12), that passes through a wall (11) or ceiling, has a frame (16) and a block (20) of optionally intumescent material disposed therein, and is characterized in that the frame (16) is of modular construction.

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.

A textile sleeve for protecting an elongated member comprises a tubular body, made from a woven or braided fiberglass yarn, having an inner surface and an outer surface. A coating adheres to the outer surface providing heat resistance to said tubular body. The coating is a silicone rubber containing phenyl partially disposed therein. According to one aspect, the silicone rubber is a phenyl containing polysiloxane. According to another aspect, the silicone rubber has a formula of RSiO.sub.3/2 wherein R includes phenyl and oxygen or R consists of phenyl and oxygen. The tubular body has a heat resistance of at least 550 C. A method of making the textile sleeve is also disclosed herein.

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 the frame (16) is of modular construction.

A fireproof cladding material for covering or coating a plastic pipeline, includes a cross-sectional structure formed by needle punch or thermal bond to form a two-layer or three-layer laminated structure with an integrated structure. The laminated structure of the cross-sectional structure is composed of a fireproof fiber woven blanket having a thickness of 0.2-250 mm, and an upper side or a lower side of the fireproof fiber woven blanket, or both sides of the upper side and the lower side thereof, is composed of a fireproof reinforcement layer with a thickness of 0.015-0.5 mm. The fireproof cladding material has the characteristics of softness, bendability, light weight and high strength, and is suitable for covering or coating plastic pipelines.

A fire protection element includes a mat of intumescent material, a reinforcing liner and ventilation holes. Furthermore, a fire protection wrap is used as a fire protection element of this type.

A line feed-Through for feeding a line through a building component can include one or more sealing arrangements for feeding the line through, wherein the one or more sealing arrangements have at least two sealing structures lying opposite each other, wherein at least one first of the sealing structures has an arrangement of elongate fins adjacent to each other, the protruding ends of which lie against a second of the sealing structures and thus seal the passage region.

A protective cover for cable connectors and methods of fabricated the protective cover. The protective cover comprises a tube open at one end and substantially closed at the opposed end by an end cap. The end cap bears at least one opening formed therein. The protective cover has a foil outer layer, a soft felt inner layer, and an insulating fiberglass core between the outer and inner layers. The tube is made by overlappingly rolling and bonding a section of foil-backed fiberglass. The end cap may be separately made, made as part of the pattern for the tube, or may be formed by cutting pointed teeth into one end of the tube pattern and bonding them generally perpendicularly to the length of the tube.

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, and a sealing system forming a water tight seal around the plurality of conductors in the openings, a first support structure extending longitudinally from a first side of the barrier support plate, the first support structure connected to the barrier support plate by a first flexible joint, and a second support structure extending longitudinally from a second side of the barrier support plate, the second support structure connected to the barrier support plate by a second flexible joint. 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 poke-through device for installation in a hole in a floor structure, the floor structure defining a floor in a first working environment and a ceiling in a second working environment, the hole communicating between the first and second working environments, the poke through device. The poke-through device includes a body defining an interior and having an upper end and a lower end. A mounting frame is adapted to secure an electrical device within the body. A first intumescent member is disposed at the body upper end, and an electrical box is secured to the body lower end. A fire resistant gasket is disposed between the electrical box and the body lower end. The gasket includes openings therein to permit passage of wiring between the electrical box and the body.
