Description
Technical Field
The utility model relates to the technical field of cables, in particular to a fireproof cable.
Background
At present, the need for rapid data and information transfer, and the reliance on computers, word processors, telex, sensors and communication devices has increased significantly and rapidly. The advent of new technology has enabled the connection and networking of devices in this regard, resulting in the comprehensive development of communication systems. The use of these systems in particular areas has increased, such as in high-rise buildings, ships, airplanes, trains, drilling platforms and mines. To connect these electronic components, a large number of wires and cables are required in these structures and fields. Typically, installation of wires and cables in air conditioning systems and wire and cable ducts is a convenient application. Since air conditioning and wire and cable ducts are continuous through these devices, the safety of the insulation and jacket materials is a fundamental requirement, namely that these materials have low flame propagation and smoke formation rates, and that different physical properties are performed under various adverse environmental conditions.
A common fireproof cable adopts an outer sheath, a mineral layer and a copper wire conductor to be wrapped with a mica tape, and the cable has limited fireproof performance and can not supply power for important equipment for a long time under the condition of continuous high temperature or burning.
Disclosure of utility model
In order to solve the above problems, namely, the problems set forth in the background art, the utility model provides a fireproof cable, which comprises three groups of cable cores and armor layers, wherein the outer wall of each group of cable cores is coated with a wire core protection layer, the outer side of one group of wire core protection layers is coated with a shielding layer, fireproof filler is filled between the shielding layer and one group of wire core protection layers, the outer side of the shielding layer is coated with a flame retardant layer, the outer side of the flame retardant layer is coated with an insulating layer, and the outer side of the insulating layer is coated with the armor layer;
A group of uniformly arranged stabilizing strips are inserted between the flame-retardant layers and the shielding layers.
The utility model is further provided with: the flame-retardant layer is made of magnesium hydroxide.
The utility model is further provided with: one group of the stabilizing strips is made of ceramic fiber materials.
The utility model is further provided with: each group of cable cores are formed by twisting a plurality of copper wires.
The utility model is further provided with: the fireproof filler is expandable graphite powder.
The utility model is further provided with: the diameter of the cable wire of each group of cable cores is 3-12mm.
The beneficial technical effects of the utility model are as follows: the cable core is located at the center of the cable and can resist external impact to protect the inner cable core from deformation through the set of stabilizing strips, the purpose of flame retardance and fire prevention is achieved on the cable through the flame retardance layer matched with the fireproof filler, the cable core is protected during daily use through the armor layer, and each set of cable core is fastened through the wire core protection layer, so that the cable is prevented from being loose.
