Description

Technical Field

[0001] The utility model relates to the technical field of composite cables, in particular to a fire-proof and corrosion-resistant composite cable. Background Art

[0002] Transportation and distribution cables made of composite materials, which have the advantages of high strength, good designability, no creep, corrosion resistance and ease of use;

[0003] For example, the Chinese authorized patent with announcement number CN201956112U (a high-temperature resistant optical fiber composite cable): includes an insulating core, an optical unit, a filling rope, a wrapping tape and a sheath. The high-temperature resistance of the composite cable is significantly enhanced through the above wrapping tape and sheath structures. All components in the composite cable can meet the requirements of long-term use under high temperature conditions, and can simultaneously realize the two major functions of power supply and optical fiber transmission in special high-temperature places. The composite cable also has excellent oil resistance and chemical resistance. The product is suitable for use in special high-temperature places such as metallurgy and petrochemicals.

[0004] However, the existing composite cables have a single structure, and most of them rely on their own composite material outer sheath for fire protection and corrosion resistance, resulting in a short service life; therefore, they do not meet existing needs. In this regard, we propose a composite cable with fire protection and corrosion resistance. Utility Model Content

[0005] The utility model aims to provide a fireproof and anti-corrosion composite cable to solve the problem that the existing composite cables mentioned in the above background technology have a single structure and most of them rely on their own composite material outer sheath for fireproof and anti-corrosion, resulting in a short service life.

[0006] To achieve the above object, the utility model provides the following technical solution: a fire-proof and corrosion-resistant composite cable, comprising: an outer sheath, an armor is arranged inside the outer sheath, an inner sheath is arranged inside the armor, a conductor assembly is arranged inside the inner sheath, and a filler is arranged between the conductor assembly and the inner sheath;

[0007] Also includes:

[0008] An inner steel belt is arranged inside the armor, an outer steel belt is arranged outside the inner steel belt, a flame retardant fiber is arranged between the inner steel belt and the outer steel belt, and a flame retardant fabric is arranged outside the flame retardant fiber;

[0009] The convex ball is arranged on the outer wall of the outer sheath, and the convex ball and the outer sheath are an integral structure, and a plurality of the convex balls are arranged.

[0010] Preferably, an inner protective ring is arranged inside the outer sheath, an outer protective ring is arranged outside the inner protective ring, a connecting seat is arranged between the inner protective ring and the outer protective ring, and the inner protective ring is fixed to the outer protective ring through the connecting seat.

[0011] Preferably, a conductor is disposed inside the conductor assembly, and a conductor shielding layer is disposed outside the conductor.

[0012] Preferably, an insulating layer is arranged outside the conductor shielding layer, and an insulating shielding layer is arranged outside the insulating layer.

[0013] Preferably, the outer surface of the convex ball and the outer surface of the outer sheath are both provided with anti-corrosion coating, and the anti-corrosion coating is sprayed on the outer surfaces of the convex ball and the outer sheath.

[0014] Preferably, the inner protective ring and the outer protective ring are both made of composite materials, and the convex ball is also made of composite materials.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model arranges convex balls on the outer wall of the outer sheath. The outer sheath is composed of convex balls, inner protective ring and outer protective ring. There is a gap between the inner protective ring and the outer protective ring. When the outer protective ring is damaged, the inner protective ring continues to play a protective effect, thereby achieving double protection and improving the service life. At the same time, the convex balls are used to prevent the outer sheath from contacting the ground and the wall, preventing the outer surface of the composite cable from being damaged by friction when in use, and preventing corrosion damage to the connection with the ground and the wall due to moisture, thereby improving the service life.

[0017] 2. By arranging flame-retardant fabrics and flame-retardant fibers inside the armor, the inner sheath is sandwiched by the inner steel belt and the outer steel belt, and the inner sheath is wrapped by the armor composed of the inner steel belt, the outer steel belt, the flame-retardant fabric and the flame-retardant fiber, thereby improving the overall flame retardant and fireproof performance and improving safety.
