Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable equipment, and more specifically to a new type of low-temperature resistant cable. Background Art
[0002] Existing cable equipment often exhibits many limitations in low-temperature environments. Especially in extremely cold conditions, cable materials tend to become brittle and lose flexibility, leading to problems such as cable cracking and breaking. When traditional cables are used in low-temperature environments, the mechanical strength of their insulation layers and outer sheath materials will be significantly reduced, making them extremely vulnerable to external forces. In addition, the icing problem in low-temperature environments may also cause the cable to expand in volume, thereby damaging the internal structure and affecting the transmission performance of the cable. Content of the Utility Model
[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a new type of low-temperature resistant cable to solve the problem that when existing traditional cables are used in low-temperature environments, the mechanical strength of their insulation layers and outer sheath materials will be significantly reduced, making them extremely vulnerable to external forces as described in the above background art.
[0004] The utility model provides the following technical solution: A new type of low-temperature resistant cable, including a cable insulation sleeve. Four cable main structures are arranged inside the cable insulation sleeve. A support mounting frame is fixedly installed inside the cable insulation sleeve, and the shape of the support mounting frame is cross-shaped. The cable main structures are all installed in the gap between the cable insulation sleeve and the support mounting frame. The main structure of the cable insulation sleeve is fluororubber. A layer of anti-icing isolation layer is fixedly installed on the outer surface of the cable insulation sleeve, and a layer of anti-ice rupture layer is fixedly installed on the outer surface of the anti-icing isolation layer. The main structure of the anti-icing isolation layer is polytetrafluoroethylene, and the main structure of the anti-ice rupture layer is thermoplastic polyurethane. The cable insulation sleeve uses fluororubber as the main material to ensure that the cable has excellent anti-brittleness and flexibility in low-temperature environments, and can maintain good structural stability at extremely low temperatures. The cross-shaped structure of the support mounting frame further enhances the internal support force of the cable insulation sleeve, preventing it from being broken by ice and snow in icing and blizzard weather. The anti-icing isolation layer has an extremely low friction coefficient, is not easy to absorb water, and prevents the internal structure from being damaged due to volume expansion after icing. The anti-ice rupture layer provides additional elasticity and compressive performance for the cable, enabling the cable to still maintain strength and flexibility under harsh conditions. It effectively solves the problem that when existing traditional cables are used in low-temperature environments, the mechanical strength of their insulation layers and outer sheath materials will be significantly reduced, making them extremely vulnerable to external forces.
[0005] Furthermore, a compression-resistant layer is fixedly installed on the inner wall of the ice-breaking layer. A thermal expansion buffer layer is fixedly installed on the outer surface of the anti-icing isolation layer. The inner wall of the compression-resistant layer is fixedly connected to the outer surface of the thermal expansion buffer layer. The main structure of the compression-resistant layer is a stainless steel wire mesh, and the main structure of the thermal expansion buffer layer is microbubble foam cotton. The fixed installation of the compression-resistant layer on the inner wall of the ice-breaking layer effectively enhances the overall mechanical strength of the cable, prevents the cable from deforming under external pressure or low-temperature conditions. The thermal expansion buffer layer further provides a buffer layer that can absorb the expansion force and contraction force during drastic temperature changes, preventing the cable from deforming due to thermal expansion and contraction, and ensuring the durability of the cable in complex environments.
[0006] Furthermore, a plurality of structure strengthening rings are evenly and fixedly installed on the outer surface of the ice-breaking layer. The main structure of each structure strengthening ring is solid anti-slip rubber. The structure strengthening rings enable the cable to have better anti-slip performance in low-temperature environments, increasing the safety and stability of the cable during installation and use, and preventing the cable from sliding or being damaged due to low-temperature icing.
[0007] Furthermore, an internal support rib is fixedly installed at the geometric center inside the support mounting frame. The gap between the main cable structure and the support mounting frame is evenly filled with fireproof asbestos. The main structure of the internal support rib is carbon fiber. The installation of the internal support rib at the geometric center of the support mounting frame enables the cable to have stronger tensile strength and toughness, preventing it from breaking under low-temperature or external force. At the same time, the gap between the main cable structure and the support mounting frame is evenly filled with fireproof asbestos, effectively improving the fire resistance and safety of the cable.
[0008] Furthermore, a plurality of heating resistance wires are inlaid and installed inside the support mounting frame, and all the heating resistance wires are electrically connected to an external power source. A plurality of heating resistance wires are inlaid inside the support mounting frame. These electric heating elements are connected to an external power source and can maintain the temperature inside the cable by heating at extremely low temperatures, avoiding the cable from freezing or being affected by low temperatures, and ensuring the normal operation of the cable in low-temperature environments.
[0009] Furthermore, a waterproof layer is fixedly installed on the outer surface of the main cable structure. The main structure of the waterproof layer is cross-linked polyethylene. The waterproof layer is provided on the outer surface of the main cable structure, and the main material of the waterproof layer is cross-linked polyethylene, enhancing the waterproof performance of the cable, effectively preventing moisture from invading the inside of the cable in low-temperature environments, and thus improving the service life and safety of the cable under humid and low-temperature conditions.
[0010] The technical effects and advantages of the present utility model:
[0011] 1. The utility model effectively solves the problem that when the existing traditional cables are used in a low-temperature environment, the mechanical strength of their insulating layer and external sheath materials will be significantly reduced, and they are extremely vulnerable to external damage, by providing a cable insulating sleeve, a cable main structure, a support mounting frame, an anti-icing isolation layer, and an anti-ice cracking layer.
[0012] 2. The utility model effectively enhances the overall mechanical strength of the cable and prevents the cable from deforming under external pressure or low-temperature conditions by providing a compressive layer and a thermal expansion buffer layer, with the compressive layer fixed to the inner wall of the anti-ice cracking layer. The thermal expansion buffer layer further provides a buffer layer that can absorb the expansion force and contraction force during drastic temperature changes, preventing the cable from deforming due to thermal expansion and contraction, and ensuring the durability of the cable in a complex environment.
