Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing, and in particular to multi-core branch composite cables. Background Technology

[0002] With the acceleration of industrialization, modern buildings are developing towards high-rise and large-scale structures, placing higher demands on the reliability, safety, and economy of power supply systems. Multi-core branch cables can meet the power distribution needs of different floors and areas within a building, reducing the number of cables laid and the space occupied, and improving the reliability and flexibility of power supply. For example, in the electrical shafts of high-rise buildings, multi-core branch cables can easily achieve vertical power supply, providing power to the distribution boxes on each floor. Meanwhile, multi-core branch cables are also widely used in factories, shopping malls, hospitals, and other places. In vibration environments, the connection points of multi-core branch cables, such as branch joints, are prone to loosening due to vibration, leading to increased contact resistance, which in turn causes localized heating, accelerates the aging of cable insulation, and affects the stability and reliability of the power supply system. During the transmission of electrical energy, heat is generated, which accumulates inside the cable, causing the cable temperature to rise, accelerating the aging of the cable insulation material, reducing insulation performance, and shortening the cable's service life.

[0003] Meanwhile, during installation, it is difficult to accurately fix the cable in the predetermined position, and it is easy for it to be offset or misaligned, resulting in uneven cable laying. This will cause the cable to be subjected to unnecessary external pulling or squeezing during subsequent use, affecting its performance and service life. When installing the cable, the staff need to spend more time and effort to determine the position of the cable and fix it, reducing work efficiency and reducing the stability of the cable after installation. Utility Model Content

It also has a certain degree of conductivity, which can help shield external electromagnetic interference and reduce the impact of electromagnetic interference on the signal transmission inside the cable.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a multi-core branch composite cable, including an insulation layer 101, a stainless steel wire spiral layer 102, and a shock-absorbing component. The shock-absorbing component is disposed inside the insulation layer 101. The stainless steel wire spiral layer 102 is disposed inside the insulation layer 101. An outer shielding layer 103 is disposed outside the insulation layer 101. An outer shielding wrapping layer 104 is disposed outside the outer shielding layer 103. A braided shielding layer 105 is disposed outside the outer shielding wrapping layer 104. A braided shielding wrapping layer 106 is disposed outside the braided shielding wrapping layer 105. A cable core wrapping layer 107 is disposed outside the braided shielding wrapping layer 106. The gap between the cable core wrapping layer 107 and the braided shielding wrapping layer 106 is filled with silicone foam 10. 8. The insulation layer 101 isolates the conductor 202 inside the cable from the outside world, preventing current leakage to the outside of the cable, preventing electric shock and electrical short circuits, limiting the flow of current within the specified conductor 202, and ensuring safe and efficient power transmission. The stainless steel wire spiral layer 102 has high strength and hardness, which can enhance the overall mechanical strength of the cable, resist external compression, tension and other mechanical stresses, prevent the cable from being damaged by external forces, and also has a certain degree of conductivity, which can help shield external electromagnetic interference and reduce the impact of electromagnetic interference on signal transmission inside the cable. When the cable is subjected to external vibration and impact, the silicone foam 108 can effectively absorb energy, ensuring the integrity and stability of the cable structure and reducing the probability of failure.

[0021] Please see Figures 1-4 In this embodiment, an inner shielding layer 109 is provided inside the insulation layer 101, an isolation layer 201 is provided inside the inner shielding layer 109, and a conductor 202 is provided inside the isolation layer 201. The conductor 202 is the core part of the cable. The isolation layer 201 can form a physical barrier between the conductor 202 and the inner shielding layer 109, preventing burrs, impurities, etc. on the surface of the conductor 202 from directly contacting the inner shielding layer 109, thus avoiding electrical faults caused by poor contact or partial discharge. The inner shielding layer 109 can homogenize the electric field on the surface of the conductor 202 and reduce the local electric field strength.

[0022] Please see Figures 1-3 In this embodiment, an inner protective sleeve 203 is provided outside the cable core wrapping layer 107, and an outer protective sleeve 204 is provided outside the inner protective sleeve 203. Aluminum heat dissipation fins 205 are provided outside the outer protective sleeve 204. Multiple sets of aluminum heat dissipation fins 205 are provided and evenly distributed on the outer side of the outer protective sleeve 204. Three sets of each of the following layers are provided: conductor 202 and isolation layer 201, inner shielding layer 109, insulation layer 101, stainless steel wire spiral layer 102, outer shielding layer 103, outer shielding wrapping layer 104, braided shielding layer 105, and braided shielding wrapping layer 106. The inner and outer protective sleeves 203 and 204 are evenly distributed inside the cable core wrapping layer 107. A slot 206 is provided above the outer protective sleeve 204. A magnetic strip 207 is fixedly connected inside the slot 206 to fix multiple sets of conductors 202 and related wrapping layers together to form a regular cable core structure. By wrapping, the relative movement of each part is restricted, enhancing the integrity and stability of the cable core. The inner protective sleeve 203 and the outer protective sleeve 204 can protect the cable core. Aluminum has good thermal conductivity. The heat dissipation fins increase the contact area between the outer surface of the cable and the air, accelerating heat dissipation.

[0023] During operation, the insulation layer 101 isolates the conductor 202 inside the cable from the outside environment, preventing current leakage to the outside of the cable, preventing electric shock and electrical short circuits, and limiting the current flow within the conductor 202 to ensure safe and efficient power transmission. The stainless steel wire spiral layer 102 has high strength and hardness, which enhances the overall mechanical strength of the cable, resists external compression, tension and other mechanical stresses, and prevents damage to the internal structure of the cable due to external forces. It also has a certain degree of conductivity, which can help shield external electromagnetic interference and reduce the impact of electromagnetic interference on signal transmission within the cable. When the cable is subjected to external vibration and impact, the silicone foam 108 can effectively absorb energy, ensuring the integrity and stability of the cable structure and reducing the probability of failure. The conductor 202 is the core part of the cable, and the insulation layer 201 can form a physical barrier between the conductor 202 and the inner shielding layer 109 to prevent the conductor 202 from being damaged. Burrs and impurities on the surface of conductor 202 come into direct contact with the inner shielding layer 109, preventing electrical faults caused by poor contact or partial discharge. The inner shielding layer 109 can homogenize the electric field on the surface of conductor 202, reduce the local electric field strength, and fix multiple sets of conductors 202 and related covering layers together to form a regular cable core structure. By wrapping, the relative movement of each part is restricted, enhancing the integrity and stability of the cable core. The inner protective sleeve 203 and the outer protective sleeve 204 can protect the cable core. Aluminum has good thermal conductivity, and the heat dissipation fins increase the contact area between the outer surface of the cable and the air, accelerating heat dissipation. When installing the cable, the magnetic strip 207 can accurately position and fix the cable to be installed. The generated adsorption force can be used to attract and fix another set of cables, preventing the cable from shifting during subsequent installation, making it convenient for workers to use and improving installation efficiency.

[0024] Through the above steps, the insulation layer 101 can isolate the conductor 202 inside the cable from the outside world, prevent current leakage to the outside of the cable, prevent electric shock and electrical short circuits, limit the flow of current within the specified conductor 202, and ensure safe and efficient transmission of electrical energy. The stainless steel wire spiral layer 102 has high strength and hardness, which can enhance the overall mechanical strength of the cable, resist external compression, tension and other mechanical stresses, prevent the cable from being damaged by external forces, and also has a certain degree of conductivity, which can help shield external electromagnetic interference and reduce the impact of electromagnetic interference on signal transmission inside the cable. When the cable is subjected to external vibration and impact, the silicone foam 108 can effectively absorb energy, ensure the integrity and stability of the cable structure, and reduce the probability of failure.
