Problems solved by technology

Because ordinary XLPE insulated power cables do not have fire resistance, they cannot keep the power supply line running safely and stably under flame conditions. In the event of a fire, the cable will quickly catch fire and stop power supply, which is not conducive to the evacuation of personnel. Evacuation and Fire Rescue

Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] The invention provides a cross-linked polyethylene insulated fire-resistant and flame-retardant power cable, which effectively prolongs the flame-retardant time of the flame-retardant layer and effectively prolongs the normal power-on time of related alarm and safety indicating equipment. Please refer to figure 1 , including a copper conductor 100, the outer wall of the copper conductor 100 is sleeved with an insulating layer 110, the outer wall of the i...

Abstract

The invention discloses a crosslinked polyethylene insulating fireproof flame-retardant power cable in the technical field of cables. The cable comprises a copper conductor, and the outer wall of thecopper conductor is sleeved by an insulating layer. The outer wall of the insulating layer is sleeved by a shielding layer. The outer wall of the shielding layer is sleeved by a flame-retardant layer,and a heat conduction frame is arranged in the flame retardant layer. The heat conduction frame comprises ferrules, and the ferrules are uniformly arranged in the flame-retardant layer, wherein a connecting rod is welded between the ferrules. Through holes are formed in the outer walls of the ferrules and the connecting rod, and the outer wall of the flame-retardant layer is sleeved by a mineralinsulating layer, wherein the outer wall of the mineral insulating layer is sleeved by an outer protective sleeve. According to the cable, the heat conduction frame is arranged in the flame retardantlayer; when the cable encounters a fire, the local flame-retardant layer is heated to enable the heat conduction frame to be heated to conduct heat, the flame-retardant layer at the heated heat conduction frame is heated to decompose water vapor, the water vapor moves towards the burning damage position of the cable due to pressure, the flame-retardant time of the flame-retardant layer is effectively prolonged, and the normal power-on time of related alarm and safety indication equipment is effectively prolonged.

Description

technical field [0001] The invention discloses a cross-linked polyethylene insulated fire-resistant and flame-retardant power cable, and specifically belongs to the technical field of cables. Background technique [0002] With the increase of densely populated places such as intelligent buildings and high-rise buildings, XLPE insulated fire-resistant power cables with rated voltages of 8.7 / 10kV have been used in the power supply systems of these facilities. Because ordinary XLPE insulated power cables do not have fire resistance, they cannot keep the power supply line running safely and stably under flame conditions. In the event of a fire, the cable will quickly catch fire and stop power supply, which is not conducive to the evacuation of personnel. Evacuation and fire rescue. Contents of the invention [0003] The object of the present invention is to provide a cross-linked polyethylene insulated fire-resistant and flame-retardant power cable to solve the problems raise...
