Claim:
A cable tray preserving cable support functionality under fire impact, wherein the cable tray comprises a bed for laying at least one cable in a longitudinal direction and supporting the at least one cable, which bed extends over a length of the cable tray in the longitudinal direction, wherein the bed has a U-shaped cross-section when viewed in the longitudinal direction, the U-shaped bed forming a channel with side-walls extending in the longitudinal direction and with open longitudinal ends to enable at least one cable to extend over plural cable trays arranged behind one another in the longitudinal direction, wherein the bed is made from electrically non-conductive and fire resistant textile woven material which is embedded in resin and the textile woven material is provided on both longitudinal ends 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 between the attachment devices to still support the at least one cable, wherein the attachment devices comprise a beam at which the textile woven material is attached, the beam extending transverse to the longitudinal direction at least over the entire width of the bed below the U-shaped cross-section of the bed.
