High-temperature-resistant cable for electric appliance control

Abstract

The invention discloses a high-temperature-resistant cable for electric appliance control in the technical field of cables, and the cable comprises a central reinforcing core, a grounding wire core and communication wire cores; the two groups of communication wire cores are arranged in a left cavity, a shielding layer is arranged on the outer side of a heat dissipation ring, and a heat-conducting silicone rubber filling layer is arranged between the inner wall of the shielding layer and the outer wall of the heat dissipation ring; a plurality of groups of elastic extrusion blocks are arranged on the outer wall of the heat dissipation layer in an annular array mode, elastic rubber layers are fixedly arranged on the outer walls of the plurality of groups of elastic extrusion blocks, and an arc-shaped heat insulation plate is arranged between every two adjacent groups of elastic extrusion blocks. The arc-shaped heat insulation plate is arranged, so that external high temperature can be well prevented from being transmitted to the interior of the cable; The first air separation layer and the second air separation layer formed by separation of the arc-shaped heat insulation plate prevent external heat from being transmitted to the interior of the cable to damage the internal structure when the periphery of the cable is on fire, so the high-temperature-resistant performance of the cable is further improved, and the cable has the advantages of being resistant to high temperature, flame-retardant, environmentally friendly and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high temperature resistant cable used for electrical control. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest wire and cable production and control cable country. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. [0003] Existing cables cannot withstand high temperatures in the event of a fire, which can easily cause damage to the cables. At the same time, the internal high temperature cannot be effectively dissipated during long-term use, resulting in a short service ...

Problems solved by technology

[0003] Existing cables cannot withstand high temperatures in the event of a fire, which can easily cause damage to the cables. At the same time, the internal high temperature cannot be effectively dissipated during long-term use, resulting in a short service life of the cables. Therefore, we propose a method for electrical appliances Controlled high temperature cables
