Technical Field

[0001] The 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 wires 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-combustibility. During the use of existing high temperature resistant silicone rubber cables, the waterproof performance of the cables is poor, the surface of the cables is prone to aging, and water seepage occurs, which causes damage to the internal structure of the cables 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, so that the cables are in contact with the ground, and water accumulation is likely to occur, 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:

[0006] The method for laying the high temperature resistant silicone rubber cable is as follows: passing the cable through the laying port on the laying device, and making the bottom of the cable cooperate with the installation clamping plate on the laying device for installation, the positioning mechanism on the laying device cooperates with the bottom of the cable for positioning, and then the installation clamping plate moves upward to cooperate with the laying device to fix the cable, and finally, the external components are fixedly connected through the fixing mechanism on the top of the laying device;

[0007] The erector includes a erector body, which is a square frame structure. A mounting clamp that slides up and down is provided at the inner bottom of the erector body. Two groups of driving components connected to the mounting 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 mounting clamp. A fixing mechanism is provided on the outer top of the erector body.

[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 raised strips and drainage grooves between the raised strips, water accumulation in the cable laid on the ground can be avoided, thereby avoiding water accumulation at the cable. On the basis of the raised strips, the present invention provides a laying device to keep the cable away from the ground, further avoiding water accumulation, reducing water seepage, and increasing the service life of the cable.
