DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1-3 A cable with protective armor in this embodiment includes a cable body 1, the cable body 1 is composed of a wire core 101 and a reinforcement structure, and an installation component is arranged outside the cable body 1.

[0024] Embodiment 1: The reinforcement structure includes an insulating sleeve 102 arranged outside the wire core 101, and a protective sleeve 1011 is fixedly connected to the outside of the wire core 101. The size of the protective sleeve 1011 is smaller than that of the insulating sleeve 102. The protective sleeve 1011 is rubber. The molecular chains of rubber can be cross-linked. When the cross-linked rubber is deformed by external force, it has the ability to recover quickly and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry and is widely used in the manufacture of tires, hoses, tapes, cables and other various rubber products. The insulating sleeve 102 is cross-linked polyethylene. Cross-linked polyethylene is a high-performance insulating material with low dielectric loss, low dielectric constant and excellent electrical breakdown resistance. It also has good heat resistance, cold resistance and chemical stability, and is suitable for high-voltage cables, motors and transformers and other high-demand electrical equipment. Through the mutual cooperation of the protective sleeve 1011 and the insulating sleeve 102, the insulation of the cable is increased and the cable short circuit is reduced.

[0025] Among them, a filling layer 1021 is arranged inside the insulating sleeve 102, and talcum powder is filled inside the filling layer 1021. Talc powder has good physical properties, such as lubricity, heat insulation and hygroscopicity. The lubricity will make the wire inside the cable less likely to be damaged when stretched, reduce the resistivity of the conductor inside the cable, make the current more stable, and improve the service life of the cable; the heat insulation performance will reduce the impact of external factors on the wires and cables and improve the safety of the cables. The hygroscopic performance can reduce the corrosion of the cables by moisture during transportation and storage of the cables. A heat insulation layer 103 is arranged outside the insulating sleeve 102. The thickness of the heat insulation layer 103 is one millimeter. The inner wall of the heat insulation layer 103 is fixedly connected to the insulating sleeve 102. The heat insulation layer 103 is graphene. Graphene is a new type of high-performance material with the advantages of high thermal conductivity, good chemical stability, high mechanical strength, etc. It has been more and more widely used in the field of cable insulation. It has excellent thermal and electrical conductivity, can effectively reduce the temperature of the cable, and improve the safety performance of the cable.

[0026] Among them, the heat insulation layer 103 is fixedly connected to the outside with a protective armor layer 104, the thickness of the protective armor layer 104 is three millimeters, and the thickness of the protective armor layer 104 is three times that of the heat insulation layer 103. The protective armor layer 104 is composed of aluminum wire, which has the advantages of light texture, easy to add, and easy to process, which reduces the weight of the cable and facilitates the transportation and installation of the cable. The protective armor layer 104 is fixedly connected to the outside with a flame retardant layer 105, and the flame retardant layer 105 is fixedly connected to the outside with an anti-corrosion layer 106. The thickness of the flame retardant layer 105 is two millimeters, and the flame retardant layer 105 is a low-smoke zero-halogen material. The main characteristics of the low-smoke zero-halogen material are non-toxicity, non-corrosiveness, good fire resistance, and no toxic gas is generated during use. The thickness of the anti-corrosion layer 106 is two millimeters. The anti-corrosion layer 106 is polyethylene, which is an insulating material with good mechanical strength and impact resistance, good aging resistance and low temperature resistance, low price and good chemical stability. It is suitable for buried cables, low-voltage cables, communication cables and other fields. The outside of the anti-corrosion layer 106 is sprayed with anti-corrosion paint, and the flame retardant layer 105 is used to enhance the fire resistance of the cable, reduce the toxic gases generated during the use of the cable, and the anti-corrosion layer 106 is used to enhance the corrosion resistance and aging resistance of the cable, thereby increasing the service life of the cable.

[0027] It should be noted that by setting up a reinforced structure, the corrosion resistance and aging resistance of the cable are enhanced, the corrosion and aging caused by the external environment to the cable are reduced, and the fire resistance of the cable enhanced by multiple fire protection and thermal insulation is solved. If the corrosion resistance of the cable is not enhanced, the external environment will cause aging of the cable during the long-term use of the cable, affecting the fire resistance and service life of the cable.

[0028] Specifically, when the armored cable is in use, the anti-corrosion layer 106 increases the corrosion resistance and aging resistance of the cable body 1, reduces the corrosion of the cable body 1 by acids, alkalis, salts or the external environment, protects the flame retardant layer 105, reduces the aging damage of the flame retardant layer 105, and ensures the fire resistance of the cable body 1 as much as possible. At the same time, the protective armor layer 104 and the thermal insulation layer 103 protect the insulating sheath 102 and the core 101 inside the cable body 1, reduce the damage to the insulating sheath 102 caused by high temperature or severe stretching, and through multi-layer composite, the purpose of strengthening the cable, reducing the corrosion and aging of the cable by the external environment, and increasing the service life of the cable is achieved.

[0029] Example 2: Please refer to Figure 1-3The mounting assembly includes a mounting seat 2 that is sleeved with the cable body 1, the mounting seat 2 has a threaded adjustment rod 3 connected to the inner thread of the mounting seat 2, and an arc-shaped pressing block 4 is fixedly connected to the outer side of the threaded adjustment rod 3, and a bearing 301 is fixedly connected to the bottom end of the threaded adjustment rod 3, and the bearing 301 is fixedly connected to the arc-shaped pressing block 4, which is convenient for the user to twist the threaded adjustment rod 3, and the threaded adjustment rod 3 is twisted to drive the arc-shaped pressing block 4 to move downward, so that the arc-shaped pressing block 4 and the cable body 1 are tightly fitted to limit the mounting seat 2, and the left and right sides of the mounting seat 2 are fixedly connected with mounting blocks 5, and the bottom end of the threaded adjustment rod 3 is fixedly connected to the outer side of the bearing 301, and the bearing 301 is fixedly connected to the arc-shaped pressing block 4, and the two mounting blocks 5 are symmetrically distributed, and a threaded hole 501 is opened inside the mounting block 5. The user uses a fixing screw to threadably connect the mounting block 5, and threadably connects the fixing screw to the supporting assembly to complete the installation and fixation of the mounting seat 2, which is convenient for the installation of the cable body 1.

[0030] It should be noted that by providing the installation components, it is convenient to install and fix the cables, and it is convenient for construction workers to use the cables.

[0031] Specifically, when installing the armored cable, the threaded adjustment rod 3 is screwed to drive the arc-shaped pressing block 4 to move downward, so that the arc-shaped pressing block 4 is tightly fitted with the cable body 1, and the mounting seat 2 is limited. The user uses the fixing screw to threadably connect the mounting block 5, and threadably connects the fixing screw to the supporting assembly to complete the installation and fixation of the mounting seat 2, thereby facilitating the installation of the cable body 1.

[0032] The working principle of the above embodiment is:

[0033] (1) When the cable with protective armor is in use, the anti-corrosion layer 106 increases the corrosion resistance and anti-aging properties of the cable body 1, reduces the corrosion of the cable body 1 by acids, alkalis, salts or the external environment, protects the flame retardant layer 105, reduces the aging damage of the flame retardant layer 105, and ensures the fire resistance of the cable body 1 as much as possible. At the same time, the protective armor layer 104 and the thermal insulation layer 103 protect the insulating sleeve 102 and the wire core 101 inside the cable body 1, reduce the damage to the insulating sleeve 102 caused by high temperature or severe stretching, and through multi-layer composite, the purpose of strengthening the cable, reducing the corrosion and aging of the cable by the external environment, and increasing the service life of the cable is achieved.

[0034] (2) When installing the cable with protective armor, the threaded adjustment rod 3 is screwed to drive the arc-shaped pressing block 4 to move downward, so that the arc-shaped pressing block 4 is closely fitted with the cable body 1, and the mounting seat 2 is limited. The user uses the fixing screw to threadably connect the mounting block 5, and the fixing screw to threadably connect the supporting assembly to complete the installation and fixation of the mounting seat 2, which is convenient for the installation of the cable body 1.
