Problems solved by technology
[0004] During the use of the current buried cables, it is easy to cause the internal extrusion and external damage of the cable due to external environment and construction reasons, poor protection and low strength, resulting in a short service life, and the cable is not effective after damage. Temporary protective measures will easily lead to more serious follow-up effects; at the same time, once the existing cable breaks down and catches fire, it cannot prevent the fire from spreading in time, which will easily cause greater danger, and thus more likely to cause leakage or short circuit. , and increases the production cost of the cable

Embodiment
[0037] see Figure 1-2 and Figure 5 , a buried composite cable with good protective effect, including a cable body 1, a reinforcing core 2 is arranged inside the cable body 1, the reinforcing core 2 can strengthen the cable body 1, and can improve the radial resistance of the cable body 1 tension, and to improve the bending resistance of the cable body 1, the outer wall of the reinforcing core 2 is evenly fixed and connected with four separating ribs 3, and the inner cores 6 can be separated by the action of multiple separating ribs 3, which can prevent mutual The adjacent inner cores 6 are affected by mutual contact and extrusion, and the interior of the partition rib 3 is fixedly connected with a conduction and heat dissipation layer, and the heat generated by each inner core 6 during use can be transferred to the inner protective layer through the conduction and heat dissipation layer. layer 4, and then transmits to the armor layer and the outer sheath layer 11 through th...

The invention discloses a buried composite cable with a good protection effect, and belongs to the technical field of cables. According to the invention, when a cable body is extruded and bent, an inner core body is extruded at the same time, the inner core body can be elastically supported through an elastic supporting strip, extrusion force is buffered at the same time, the protection performance and the strength of the cable body are improved; when the outside of the cable body is damaged, the protection filling glue in the cable body flows out, so that the protection filling glue can be adhered to the damaged part outside the outer sheath layer for temporary protection, and subsequent external substances and the like can be prevented from entering the inside of the cable body to cause influence. When the cable body is broken down and ignited due to the problems of short circuit and the like, after the sealing film is burnt out, the magnesium oxide powder is bounced to the periphery of the inner core body in the cable body through the restoring elastic force of the elastic film, so that the fire behavior on the inner core body can be effectively controlled, and greater danger caused by further spreading of the fire behavior is avoided.
Description
technical field [0001] The invention relates to the technical field of cables, and more specifically relates to a buried composite cable with good protection effect. Background technique [0002] A cable is a device for electric energy or signal transmission, usually composed of several or several groups of wires, which transmit power or information from one place to another. The cable has the characteristics of internal energization and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. [0003] In modern industry and life, whether it is a power system, an information transmission system, or an instrument system, it is necessary to use corresponding cables for power or information transmission. Electricity has become an essential part of life. Due to the shortage of urb...
