Cable tray, installation kit, and electrical installation

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 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 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 tray supports are configured for attachment at the attachment devices,
• wherein the attachment device comprises 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.

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 in a longitudinal direction over a length of the cable tray,
• 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 ends of the cable tray in longitudinal direction of the cable tray with a fire resistant attachment device,
• wherein the bed forms a channel in which the at least one cable is inserted,
• 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 at least one cable tray is attached with the attachment devices at tray supports.
