The bed is made from fire resistant textile woven material which is embedded in resin. The textile woven material is provided on both sides with respect to the longitudinal direction of the cable tray with a fire resistant attachment device. The attachment devices are coupled to the textile woven material, wherein, with burned-off resin, the attachment devices remain coupled to the textile woven material to take up tension force from the textile woven material when the textile woven material extends like a hammock between the attachment devices to still support the at least one cable. An installation kit for an electrical installation, and an electrical installation with cable trays of this sort are also described. ## Claims ### Claim 1 A cable tray preserving cable support functionality under fire impact, wherein the cable tray comprises a bed for laying and supporting at least one cable, which bed extends over a length of the cable tray, wherein the bed is made from fire resistant textile woven material which is embedded in resin and the textile woven material is provided on both sides with respect to the longitudinal direction of the cable tray with a fire resistant attachment device, wherein the attachment devices are coupled to the textile woven material, wherein, with burned-off resin, the attachment devices remain coupled to the textile woven material to take up tension force from the textile woven material when the textile woven material extends like a hammock between the attachment devices to still support the at least one cable. ### Claim 2 (depends on 1) The cable tray according to claim 1, wherein the textile woven material is electrically non-conductive, and wherein the textile woven material is configured to form an electrically insulating support for the cable which support extends over the entire length of the cable tray when the resin and the cable insulation have burned off under fire impact. ### Claim 3 (depends on 1) The cable tray according to claim 1, wherein the attachment device comprises a metal transversal beam at which the textile woven material is attached. ### Claim 4 (depends on 1) The cable tray according to claim 1, wherein the textile woven material is configured on both sides with respect to the longitudinal direction with a textile loop. ### Claim 5 (depends on 1) The cable tray according to claim 1, wherein at least two holes are arranged in the textile woven material on both sides respectively with respect to the longitudinal direction, and wherein the holes are offset from one another transversal to the longitudinal direction. ### Claim 6 (depends on 1) The cable tray according to claim 1, wherein the bed comprises an essentially U-shaped transversal profile configured for inserting and laterally guiding the cable, wherein the textile woven material extends over the portion of both arms and over the portion of the connecting bar of the U-shaped transversal profile. ### Claim 7 (depends on 1) The cable tray according to claim 1, wherein the textile woven material is essentially a glass fiber woven material. ### Claim 8 (depends on 1) The cable tray according to claim 1, wherein the resin is one of polyester resin, epoxy resin and phenolic resin. ### Claim 9 (depends on 1) The cable tray according to claim 1, wherein the cable tray is configured with at least one support rod for supporting the bed, and wherein the at least one support rod is oriented in longitudinal direction. ### Claim 10 (depends on 1) The cable tray according to claim 1, wherein the cable tray is configured with at least one support rod for supporting the bed, and wherein the at least one support rod is oriented in transversal direction. ### Claim 11 (depends on 1) The cable tray according to claim 1, wherein the cable tray preserves functionality up to a temperature of 1300° C. ### Claim 12 An installation kit for an electrical installation, comprising: at least one cable tray for preserving cable support functionality under fire impact, at least one fire safety cable with circuit integrity under fire impact; and at least two tray supports for mounting the at least one cable tray, wherein the cable tray comprises a bed for laying and supporting at least one cable, which bed extends over a length of the cable tray, wherein the bed is made from fire resistant textile woven material which is embedded in resin and the textile woven material is provided on both sides with respect to the longitudinal direction of the cable tray with a fire resistant attachment device, wherein the attachment devices are coupled to the textile woven material, wherein, with burned-off resin, the attachment devices remain coupled to the textile woven material to take up tension force from the textile woven material when the textile woven material extends like a hammock between the attachment devices to still support the at least one cable, wherein the tray supports are configured for attachment at the attachment devices. ### Claim 13 (depends on 12) The installation kit of claim 12, wherein the fire safety cable is a flat cable with plural power strands extending parallel to one another and adjacent to one another in a plane. ### Claim 14 An electrical installation with circuit integrity under fire impact, comprising: at least one cable tray preserving cable support functionality under fire impact, at least one cable in the cable tray; and at least two tray supports; wherein the at least one cable tray comprises a bed for laying the at least one cable, which bed extends over a length of the cable tray, wherein the bed is made from fire resistant textile woven material which is embedded in resin and the textile woven material is provided on both sides with respect to the longitudinal direction of the cable tray with a fire resistant attachment device, wherein the attachment devices are coupled to the textile woven material, wherein, with burned-off resin, the attachment devices remain coupled to the textile woven material to take up tension force from the textile woven material when the textile woven material extends like a hammock between the attachment devices to still support the at least one cable; wherein the at least one cable tray is attached with the attachment devices at tray supports. ### Claim 15 (depends on 14) The electrical installation of claim 14, wherein the cable is a fire safety cable. ### Claim 16 (depends on 15) The electrical installation of claim 15, wherein the fire safety cable is a flat cable with plural power strands extending parallel to one another and adjacent to one another in a plane. ### Claim 17 (depends on 14) The electrical installation according to claim 14, comprising a plurality of cable trays which are mounted by tray supports, wherein adjacent cable trays are mounted with a common tray support. ### Claim 18 (depends on 14) The electrical installation according to claim 14, wherein the cable tray is only mounted by tray supports which are attached at the attachment devices, so that the cable tray is self-supporting there between.
