Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a multiphase composite cable. Background Technology

[0002] With the increasing demand for power and signal transmission, the performance requirements for cables are also becoming more stringent.

[0003] Traditional cables suffer from severe signal interference, poor heat dissipation, and insufficient mechanical strength during multiphase transmission. Furthermore, in complex environments such as high temperature, humidity, and strong electromagnetic interference, the stability and reliability of traditional cables are difficult to guarantee, failing to meet the increasingly diverse needs of modern industry and daily life.

[0004] Therefore, a new type of multiphase composite cable needs to be designed to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to provide a multiphase composite cable that improves the electrical performance, mechanical performance and environmental adaptability of the cable by optimizing the cable's structural design. This effectively solves the problems of signal interference, poor heat dissipation, insufficient mechanical strength and poor environmental adaptability of traditional cables, and meets the needs of multiphase transmission and use in complex environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multiphase composite cable has a core structure comprising a cable core, an insulation layer, a shielding layer, a buffer layer, a flame-retardant layer, an armor layer, and an outer sheath. The cable core, as the key part of the cable for transmitting power and signals, is composed of multiple sub-cores. These sub-cores are arranged in a circular array around a central axis. This layout optimizes the utilization of internal space in the cable and ensures the orderly transmission of multiphase signals.

[0008] Furthermore, the sub-core includes a conductor and an inner insulation layer wrapped around the conductor. The conductor is made using a multi-strand fine copper wire stranding process, which increases the surface area of ​​the conductor, reduces resistance, and significantly improves conductivity. At the same time, thermally conductive silicone is filled between the multi-strand fine copper wires, which enhances the heat dissipation capacity of the conductor and reduces friction between the fine copper wires, thereby reducing static electricity and effectively reducing signal interference.

[0009] Furthermore, the insulation layer is tightly wrapped around the outside of the cable core and is made of cross-linked polyethylene material. With its excellent insulation and temperature resistance properties, it provides reliable insulation protection for the cable core, ensuring stable transmission of current and signals within the cable core and preventing the risk of leakage.

[0010] Furthermore, the shielding layer covers the insulation layer and consists of two layers of metal braided mesh and aluminum foil located between the two layers of metal braided mesh. The two layers of metal braided mesh and aluminum foil work together to effectively shield external electromagnetic interference and prevent the leakage of signals inside the cable, ensuring the stability and accuracy of signal transmission. Multiple evenly distributed vent holes are set on the aluminum foil, which facilitates the dissipation of heat inside the cable without affecting the shielding effect, and also reduces the overall weight of the cable.

[0011] Furthermore, the buffer layer is wrapped around the shielding layer and is made of foamed polyurethane material to form a honeycomb structure. This structure itself has good buffering performance, and the honeycomb structure is filled with rubber shock-absorbing particles, which further enhances the buffering and shock absorption effect, effectively resisting external impacts and protecting the internal structure of the cable from damage.

[0012] Furthermore, the flame-retardant layer is located outside the buffer layer and is made of halogen-free flame-retardant polyolefin material. In the event of a fire or other emergency, it can quickly exert its flame-retardant effect, effectively prevent the spread of flames, and improve the safety of the cable.

[0013] Furthermore, the armor layer, wrapped around the flame-retardant layer, is composed of interwoven stainless steel wires and aramid fiber filaments. The stainless steel wires give the cable high strength and abrasion resistance, while the aramid fiber filaments combine light weight and high strength. The combination of the two gives the cable excellent mechanical strength, enabling it to withstand greater tensile, compressive, and impact forces.

[0014] Furthermore, the outermost sheath, wrapped around the armor layer, is made of weather-resistant rubber material with anti-slip textures on its outer surface. The weather-resistant rubber material enables the cable to adapt to various harsh environments such as high temperature, humidity, and acid and alkali, extending its service life. The anti-slip texture design increases the friction on the cable surface, making the cable easier to install and use.

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

[0016] This utility model, through the design of a multiphase composite cable, achieves the following effects: 1. The conductor, composed of multiple strands of fine copper wire twisted together, combined with thermally conductive silicone, reduces resistance, enhances heat dissipation, and reduces signal interference; the double-layer metal braided mesh combined with aluminum foil in the shielding layer effectively shields electromagnetic interference, prevents signal leakage, and ensures stable and accurate transmission of power and signals in multiphase transmission; 2. The interweaving of stainless steel wire and aramid fiber in the armor layer gives the cable high strength; the honeycomb structure and shock-absorbing particles in the buffer layer effectively buffer external impacts; the anti-slip texture of the outer sheath facilitates installation and improves the overall mechanical reliability of the cable during installation and use; 3. The cross-linked polyethylene insulation layer has good insulation and temperature resistance; the halogen-free flame-retardant polyolefin flame-retardant layer provides reliable fire safety protection; the weather-resistant rubber outer sheath enables the cable to adapt to various harsh environments, ensuring long-term stable operation of the cable in complex environments.
