Description

Technical Field

[0001] This utility model belongs to the field of power cable technology, specifically, it relates to a fire-resistant, arc-resistant, and flame-retardant wrapping tape. Background Technology

[0002] With the increasing demand for electricity in modern society, the safety and stability of cables, as an important carrier of power transmission, have become particularly important. In order to improve the fire resistance and flame retardant performance of power cables, it is often necessary to wrap fire-retardant tape around the surface of the power cables.

[0003] Existing fire-resistant, arc-resistant, and flame-retardant wrapping tapes can prevent cable fires to a certain extent, but their functionality is relatively limited and cannot meet the needs of complex and ever-changing operating environments. Due to the different installation locations and climates of cables, existing fire-resistant, arc-resistant, and flame-retardant wrapping tapes cannot effectively protect cables.

[0004] To address the aforementioned issues, this application proposes a fire-resistant, arc-resistant, and flame-retardant wrapping tape. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a fire-resistant, arc-resistant, and flame-retardant wrapping tape to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire-resistant, arc-resistant, and flame-retardant wrapping tape includes a wrapping tape body, the wrapping tape body comprising fiberglass cloth, the outer wall of the fiberglass cloth being coated with a fire-resistant and flame-retardant layer, the side of the fire-resistant and flame-retardant layer away from the fiberglass cloth being coated with an arc-resistant layer, the side of the arc-resistant layer away from the fire-resistant and flame-retardant layer being coated with a protective layer, and the side of the fiberglass cloth away from the fire-resistant and flame-retardant layer being coated with a high-temperature insulating layer.

[0008] Preferably, an anti-slip pad is fixedly connected to the side of the high-temperature insulation layer away from the fiberglass cloth, and a cable is attached to the side of the anti-slip pad away from the high-temperature insulation layer.

[0009] By setting anti-slip pads and cables, the anti-slip pads ensure that the main body of the wrapping tape fits snugly against the cable, preventing the main body of the wrapping tape from slipping after wrapping and affecting the protective effect of the wrapping tape on the cable.

[0010] Preferably, the fire-resistant and flame-retardant layer is a phenolic resin composite material, and the arc-resistant layer is polyimide.

[0011] By setting a fire-resistant and flame-retardant layer and an anti-arc layer, the fire-resistant and flame-retardant layer can isolate oxygen and heat at high temperatures, while the anti-arc layer can effectively resist the damage of electric arc to the cable.

[0012] Preferably, the protective layer is nitrile rubber and the high-temperature insulating layer is polytetrafluoroethylene.

[0013] By setting up a protective layer and a high-temperature insulation layer, the cable is protected from external environmental corrosion by the protective layer, and the cable is isolated from external heat sources by the high-temperature insulation layer.

[0014] Preferably, the main body of the wrapping tape is spirally wound around the outer wall of the cable.

[0015] By setting up a wrapping tape body and a cable, the cable is protected by the wrapping tape body being spirally wound around the outer wall of the cable.

[0016] In summary, the technical effects and advantages of this utility model are as follows: This fire-resistant, arc-resistant, and flame-retardant wrapping tape, composed of a main body made of fiberglass cloth, a fire-resistant and flame-retardant layer, an arc-resistant layer, a protective layer, and a high-temperature insulating layer, wraps around the outer wall of the cable, thereby providing comprehensive protection for the cable. Each layer provides different protective effects for the cable, effectively preventing damage to the cable. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3A fire-resistant, arc-resistant, and flame-retardant wrapping tape includes a wrapping body 1, which includes a fiberglass cloth 101. The outer wall of the fiberglass cloth 101 is coated with a fire-resistant and flame-retardant layer 102. An arc-resistant layer 103 is coated on the side of the fire-resistant and flame-retardant layer 102 away from the fiberglass cloth 101. A protective layer 104 is coated on the side of the arc-resistant layer 103 away from the fire-resistant and flame-retardant layer 102. A high-temperature insulating layer 105 is coated on the side of the fiberglass cloth 101 away from the fire-resistant and flame-retardant layer 102. The wrapping body 1, composed of the fiberglass cloth 101, the fire-resistant and flame-retardant layer 102, the arc-resistant layer 103, the protective layer 104, and the high-temperature insulating layer 105, provides multi-functional protection for the cable 7, enabling it to better protect the cable 7 from external damage.

[0023] Reference Figure 1-3 An anti-slip pad 6 is fixedly connected to the side of the high-temperature insulation layer 105 away from the fiberglass cloth 101. The cable 7 is attached to the side of the anti-slip pad 6 away from the high-temperature insulation layer 105. The anti-slip pad 6 increases the friction between the wrapping body 1 and the cable 7, so that the wrapping body 1 can avoid slipping when it is wrapped around the outer wall of the cable 7. This effectively improves the protection effect of the wrapping body 1 on the cable 7 and prevents gaps from appearing after the wrapping body 1 is wrapped.

[0024] Reference Figure 1-3 The fire-resistant and flame-retardant layer 102 is a phenolic resin composite material, and the anti-arc layer 103 is a polyimide. The fire-resistant and flame-retardant layer 102 can quickly form a dense carbonized layer at high temperature, which isolates oxygen and heat, so that the fire-resistant and flame-retardant layer 102 achieves excellent fire-resistant and flame-retardant effect. The anti-arc layer 103 can effectively resist the damage of electric arc to cable 7 and prevent fire accidents caused by electric arc.

[0025] Reference Figure 1-3 The protective layer 104 is made of nitrile rubber, and the high-temperature insulation layer 105 is made of polytetrafluoroethylene. The protective layer 104 protects the cable 7 from external environmental corrosion and prevents the cable 7 from being affected by other factors. The high-temperature insulation layer 105 effectively isolates the cable 7 from external heat sources and improves the insulation performance of the cable 7.

[0026] Reference Figure 1-2 The main body 1 of the wrapping tape is spirally wound around the outer wall of the cable 7. The spiral winding of the main body 1 can increase the friction between the wrapping tape and the cable 7, ensuring that the wrapping tape can be firmly fixed on the cable 7. The spiral wrapping tape can form a tight fit during installation, reducing the gap between the cable 7 and the wrapping tape.

[0027] Working principle: By sequentially coating the outer wall of the fiberglass cloth 101 with a fire-resistant and flame-retardant layer 102, an anti-arc layer 103, and a protective layer 104, the functionality of the fiberglass cloth 101 is enhanced, improving the protective effect of the wrapping body 1 on the cable 7. By attaching a high-temperature insulation layer 105 to the side of the fiberglass cloth 101 away from the fire-resistant and flame-retardant layer 102, the insulation between the wrapping body 1 and the cable 7 is improved. The anti-slip pad 6 installed between the high-temperature insulation layer 105 and the cable 7 prevents the wrapping body 1 from slipping when it is threaded onto the outer wall of the cable 7, allowing the wrapping body 1 to be effectively installed on the outer wall of the cable 7 to protect the cable 7.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
