Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high-temperature heat-insulating and fire-proof cable. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of wires. There are many types of cables, and different cables need to be used in different environments to ensure good transmission of electrical energy or signals.

[0003] Fireproof cables are widely used under existing technologies. They are used in many places with strict requirements. In the event of a fire, they can buy a certain amount of time for rescue. Today's fireproof cables have made many improvements in their materials, so they have many fireproof properties. However, in the face of a real fire, they can only last for a short time and are inevitably easily burned.

[0004] Therefore, we proposed a high-temperature heat-insulating fireproof cable that can improve external fire insulation and ensure the stable installation of its own fireproof components to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-temperature heat-insulating fireproof cable to solve the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A high-temperature heat-insulating fireproof cable comprises a conductor, an insulating sleeve is extruded on the outer surface of the conductor, a mica tape is evenly wound on the outer surface of the insulating sleeve, a metal braided layer is woven on the outer surface of the mica tape, an outer sheath is extruded on the outer surface of the metal braided layer, an aerogel felt sleeve is provided on the outer surface of the outer sheath, a fireproof sheath is provided on the outer surface of the aerogel felt sleeve, and elastic hoops are evenly clamped on the outer surface of the fireproof sheath.

[0008] As a further solution of the utility model: the outer surface of the outer sheath is uniformly and integrally formed with convex strips, and the convex strips are uniformly provided with notches.

[0009] As a further solution of the utility model: the recessed portion clamps the outer surface of the fireproof sheath to form a binding rope, and the binding rope is located on one side of the notch.

[0010] As a further solution of the utility model: a convex block is uniformly and integrally formed inside the elastic hoop, and the side of the convex block away from the elastic hoop is arc-shaped.

[0011] As a further solution of the utility model: the width of the protrusion is equal to the distance between the protrusions, and the periphery of the protrusion is provided with an arc chamfer.

[0012] As a further solution of the utility model: a notch is provided on one side of the elastic hoop, and the elastic hoop is elastic.

[0013] As a further solution of the utility model: a waterproof tape is evenly wrapped and pasted on one side of the fireproof sheath, and the waterproof tape fixes the fireproof sheath part to one side of the outer sheath.

[0014] Beneficial effects of the utility model:

[0015] 1. A high-temperature heat-insulating fireproof cable in the utility model has a good heat-insulating effect on the cable through the aerogel felt sleeve, and because the fireproof sheath has good fireproof performance and is not easy to burn or drip, it provides good protection for the outside of the cable, and even if a fire occurs, it can ensure a good fireproof and heat-insulating effect, and the fireproof sheath can well avoid the aerogel felt sleeve from falling powder, thereby extending the service life.

[0016] 2. A high-temperature heat-insulating fireproof cable in the utility model wraps the fireproof sheath through the recessed portion, so that the fireproof sheath and the aerogel felt sheath are partially pressed inside the notch, and then the elastic hoop is clamped on the fireproof sheath, so that the convex block squeezes the fireproof sheath and the aerogel felt sheath between the convex strips, and finally it is wrapped and fixed by a waterproof tape, thereby forming a good limit for the fireproof sheath and the aerogel felt sheath, which is not easy to deviate or fall off, and ensures a good use effect.

[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 In this embodiment, a high-temperature heat-insulating fire-proof cable includes a conductor 6, an insulating sleeve 5 is extruded on the outer surface of the conductor 6, a mica tape 7 is evenly wrapped on the outer surface of the insulating sleeve 5, a metal braided layer 9 is woven on the outer surface of the mica tape 7, an outer sheath 10 is extruded on the outer surface of the metal braided layer 9, an outer surface of the outer sheath 10 is covered with an aerogel felt sleeve 13, an outer surface of the aerogel felt sleeve 13 is covered with a fire-proof sheath 1, and an elastic hoop 3 is evenly clamped on the outer surface of the fire-proof sheath 1.

[0026] like Figure 3 and Figure 4 In this embodiment, the outer surface of the outer sheath 10 is uniformly and integrally formed with convex strips 11, and the convex strips 11 are uniformly provided with notches 12, so that the fireproof sheath 1 and the aerogel felt sheath 13 can be partially inserted into the notches 12 to form a limit.

[0027] like Figure 1-Figure 4 The recessed portion 8 in this embodiment clamps the outer surface of the fireproof sheath 1 to form a binding rope 2, and the binding rope 2 is on one side of the notch 12. When the binding rope 2 is tied, the fireproof sheath 1 and the aerogel felt sheath 13 can be partially inserted into the notch 12 to form a good limit.

[0028] like Figure 1 and Figure 5 In this embodiment, a protrusion 14 is uniformly and integrally formed inside the elastic hoop 3 , and the protrusion 14 is arc-shaped on the side away from the elastic hoop 3 , so as to facilitate good downward pressing of the fireproof sheath 1 .

[0029] like Figure 1 , Figure 3 and Figure 5 In this embodiment, the width of the protrusion 14 is equal to the distance between the protrusions 11 , and an arc chamfer is provided around the periphery of the protrusion 14 to facilitate the fireproof sheath 1 and the aerogel felt sheath 13 to be partially inserted between the protrusions 11 .

[0030] like Figure 1 and Figure 5 In this embodiment, a notch is provided on one side of the elastic hoop 3 , and the elastic hoop 3 is elastic so that the elastic hoop 3 can be opened and clamped on the fireproof sheath 1 .

[0031] like Figure 1 In this embodiment, a waterproof tape 4 is evenly wrapped and pasted on one side of the fireproof sheath 1, and the waterproof tape 4 fixes part of the fireproof sheath 1 on one side of the outer sheath 10, thereby finally sealing the fireproof sheath 1 and ensuring a certain sealing performance.

[0032] It can be understood that the high-temperature heat-insulating fireproof cable has a good heat-insulating effect on the cable through the aerogel felt sleeve 13, and because the fireproof sheath 1 has good fire-proof performance and is not easy to burn or drip, it provides good protection for the outside of the cable, and even if a fire occurs, it can ensure a good fire-proof and heat-insulating effect. The fireproof sheath 1 can well prevent the aerogel felt sleeve 13 from falling off, thereby extending the service life, and the fireproof sheath 1 and the aerogel felt sleeve 13 can be firmly fixed and are not easy to deviate or fall off, thereby ensuring a good use effect.

[0033] The complete usage steps and working principle of the utility model are as follows:

[0034] First, the aerogel felt sleeve 13 is put on the outer surface of the outer sheath 10, so that the aerogel felt sleeve 13 can provide good heat insulation effect for the cable, and then the aerogel felt sleeve 13 is wrapped by the fireproof sheath 1. The fireproof sheath 1 has good fireproof performance and is not easy to burn or drip, so it provides good protection for the outside of the cable. Even if a fire occurs, it can ensure good fireproof and heat insulation effect, and the fireproof sheath 1 can well avoid the aerogel felt sleeve 13 from falling powder, thereby extending the service life;

[0035] After the fireproof sheath 1 is installed, the fireproof sheath 1 is wrapped by the recessed portion 8 so that the fireproof sheath 1 and the aerogel felt sheath 13 are partially pressed inside the notch 12, and then the elastic hoop 3 is clamped on the fireproof sheath 1 so that the protrusion 14 squeezes the fireproof sheath 1 and the aerogel felt sheath 13 so that they are partially pressed between the convex strips 11, and finally they are wrapped and fixed by the waterproof tape 4, thereby forming a good limit for the fireproof sheath 1 and the aerogel felt sheath 13, which is not easy to deviate or fall off.
