Detailed Description
The present invention will be further illustrated with reference to the accompanying figures 1-4 and the following detailed description, which should be understood to illustrate the present invention and not to limit the scope of the invention.
It should be noted that the terms "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and do not structurally limit the present invention, and the terms "inner" and "outer" refer to directions toward and away from the geometric center of a particular component, respectively.
As shown in fig. 1, a fire-resistant cable tray comprises: the cable bridge frame comprises a cable bridge frame body 1, wherein the cable bridge frame body 1 is divided into an inner layer 11 and an outer layer 12, a white mica plate 4 is filled between the inner layer 11 and the outer layer 12, and a bridge frame coverBody2 the upper layer is also provided with a white mica plate 4, the thickness of the white mica plate 4 is 2mm-2.5mm, and the heat-resistant white mica plate has excellent heat resistance, flame retardance and electric insulationAnd the muscovite board with uniform thickness is added into the bridge frame, so that the bridge frame has good electrical performance and certain mechanical strength.
As shown in fig. 1, the outer side wall and the bottom wall of the cable tray body 1 are provided with a plurality of reinforcing ribs 13, and the reinforcing ribs improve the supporting strength of the cable tray and prevent downwarping.
As shown in fig. 1, a partition plate 3 is further arranged at a position, close to the lower portion of an inner layer 11 of the cable bridge body 1, a certain distance is reserved between the partition plate 3 and the bottom of the cable bridge body 1, when a cable is laid, the cable is not in direct contact with a bottom wall of the cable bridge body, and when a fire disaster occurs, the temperature of the cable cannot rise sharply due to the fact that the cable is in direct contact with the bottom wall because of a buffer space at the lower portion.
