Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a high-temperature resistant silicone rubber cable. Background Art

[0002] High-temperature resistant wires and cables usually refer to fluoroplastic cables or Teflon cables, which are widely used in connecting lines of electrical instruments with AC rated voltages of 450 / 750V, 600 / 1000V and below, and transmission lines of automatic control systems. They have excellent properties such as oil resistance, waterproofness, wear resistance, acid and alkali resistance, various corrosive gases, aging resistance, and non-flammability. During use, the existing high-temperature resistant silicone rubber cables have poor waterproof performance, and the cable surface is prone to aging and water seepage, which causes damage to the internal structure of the cable and greatly increases the cost of cable use. Secondly, during the installation process of high-temperature resistant silicone rubber cables, the cables are generally installed on-site, causing the cables to contact the ground, which is prone to water accumulation, further exacerbating the water seepage problem of the cables. For this reason, we propose a high-temperature resistant silicone rubber cable. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention proposes a high-temperature resistant silicone rubber cable.

[0004] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0005] A high-temperature resistant silicone rubber cable, comprising a cable conductor, a filling layer wrapped around the cable conductor, a shielding layer wrapped around the filling layer, an insulating layer wrapped around the shielding layer, a high-temperature resistant silicone rubber protective layer wrapped around the insulating layer, and a waterproof sheath wrapped around the high-temperature resistant silicone rubber protective layer, wherein a hydrophobic structure is provided at the bottom of the waterproof sheath;

[0006] The high-temperature resistant silicone rubber cable is installed by passing it through the installation opening on the installation device, and the bottom of the cable is installed in conjunction with the installation clamping plate on the installation device. The positioning mechanism on the installation device cooperates with the bottom of the cable for positioning. Then, the installation clamping plate moves upward to cooperate with the installation device to fix the cable. Finally, the external components are fixedly connected by the fixing mechanism on the top of the installation device.

[0007] The erector includes a erector body, which is a square frame structure. The inner bottom of the erector body is provided with an installation clamp that slides up and down. Two groups of driving components connected to the installation clamp are provided on the left and right sides of the outside of the erector body. Two groups of positioning mechanisms are provided on the left and right sides of the installation clamp. The outer top of the erector body is provided with a fixing mechanism.

[0008] The beneficial effects of the present invention are:

[0009] The present invention provides a high-temperature resistant silicone rubber cable. By adding a waterproof sheath, the waterproof performance of the cable can be improved. By providing raising strips and hydrophobic grooves between the raising strips, water accumulation in the cable laid on the ground can be avoided, thereby avoiding water accumulation at the cable. The present invention provides a laying device on the basis of the raising strips, which can keep the cable away from the ground, further avoid water accumulation, reduce water seepage, and increase the service life of the cable.
