Abstract: Cable connectors for connecting two multicore cables are provided including a clamping sleeve, having a ceramic insulator with openings on each side of the sleeve, for accommodating core conductors. The clamping sleeve includes contact inserts passing through the clamping sleeve. Clamping elements are provided to clamp the core conductors to the contact inserts to electrically connect the multicore cables. The cable connector has a heat shrink tube that surrounds the clamping sleeve and the cables. Furthermore, cable termination including a clamping sleeve with a ceramic insulator with openings for core conductors is provided. Contact inserts are situated behind the openings to clamp the core conductors on the contact inserts establishing mechanical fixing of the core conductors on the clamping sleeve. The cable termination includes a heat shrink tube as according to the first aspect.

Abstract: A plug connection kit for connecting a branch line to a through line, comprising a plug housing and a socket housing that enclose contact inserts. Flexible cable ends are molded onto the plug housing and socket housing. The plug housing and socket housing are each manufactured by casting plastic onto a base body with the contact inserts and flexible cable ends connected thereto inserted, thus forming a solid one-piece plug and a solid one-piece socket. The female and male contact inserts are electrically connectable to one another in a contact area between the plug housing and the socket housing. The plug connection kit also includes a sealing sleeve that encases the plug housing, the socket housing, and the contact area between the two housings in order to protect the plug connection kit from penetration of water and/or dust.

Abstract: A handrail installation with emergency lighting for tunnels, comprising a handrail, a closed cable duct, at least one flat cable that is installed along the closed cable duct, and multiple branching boxes for contacting the flat cable without stripping of insulation. The branching boxes contact the flat cable within the closed cable duct. The handrail and the cable duct rest on support surfaces, which are different from one another, on the top side of multiple support members, and the handrail is provided separately from the closed cable duct and the support members, the cable duct is provided separately from the support members, and the handrail is situated above the closed cable duct. The emergency lighting includes multiple lamps situated in succession, which are placed at the branching boxes and are supplied with power by same.

Abstract: A connection device for connecting a multicore branch line to a flat cable has a connection device housing that allows the flat cable to pass through, and penetration contacts for contacting the flat cable without stripping of the insulation. The penetration contacts are situated in the connection device housing. The connection device also has an electrical disconnection point between the branch line and the flat cable, and at least one seal in the area of at least one opening of the connection device housing for protection from penetration of dust and/or water. The connection device housing is made, at least partially, of plastic, and on its outer side or inner side is coated with a diffusion barrier layer, wherein the diffusion barrier layer includes one or more layers, one of which is a metallic layer.

Abstract: Described is a riser that is secured against downward movement, having an electrical riser flat cable that extends vertically or with a vertical component, and at least one riser securing device, surrounding the flat cable, for securing the riser flat cable against downward movement by pressing the flat cable against a nonconductive pressing surface both in the absence of a fire and in the event of fire. The riser securing device includes an electrically nonconductive, fire-resistant clamping element, spaced apart from the pressing surface, that is freely movably guided in an oblique guide that reduces the distance of the clamping element from the pressing surface during downward movement of the clamping element.
