Embodiment Construction

[0023] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.

[0024] As shown in the figure, a ceramic fire-proof and high-temperature-resistant cable provided in this embodiment includes three conductors 1 and an insulating layer 2, a shielding layer 3 and a protective sheath 4 that are wrapped around the conductors 1 from the inside to the outside. 1 is a cable core composed of multiple nickel-plated copper wires twisted and pressed tightly. The conductor 1 and the insulating layer 2 form a conductive unit, and the diameter of the conductive unit accounts for 1 / 3 of the diameter of the cable body. The conductor 1 and the insulating layer 2 form a conductive unit. The insulating layer 2 is filled with a filling rope 5 to preven...

Abstract

The invention discloses a ceramic fireproof high-temperature-resistant cable. The cable comprises at least two conductors, insulation layers, a shielding layer and a protective sheath, wherein the insulation layers, the shielding layer and the protective sheath are sequentially arranged outside the conductors from inside to outside in a wrapping mode, each conductor and the corresponding insulation layer form a conductive unit, the space between each conductor and the corresponding insulation layer is filled with a filling rope used for preventing flattening, a wrapping layer covers the insulation layers, a woven layer is wound around the periphery of the wrapping layer, a high-temperature-resistant layer is arranged outside the woven layer, a graphene coating covers the high-temperature-resistant layer, the shielding layer is arranged outside the graphene coating, and a reflective layer is arranged on the outer surface of the protective sheath. The cable is simple in structure; by theadoption of layered design, each layer has a different function according to the location, and therefore the overall aging resistance, temperature resistance and climate resistance of the cable are improved; and heat insulation can be effectively performed on external temperature to maintain the working temperature inside the control cable, so that the influence of the external temperature on thecontrol cable is lowered, and the cable has a good high-temperature-resistant effect and cold-resistant effect.

Description

technical field [0001] The invention relates to the field of power grid auxiliary equipment, and relates to cables, in particular to a ceramicized fireproof and high temperature resistant cable. Background technique [0002] A cable generally refers to a rope-like cable twisted by several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and is often twisted around a center. Has a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. Cables are generally divided into power cables and communication cables. Power cables refer to a type of cable used to transmit electricity. They play the role of power transmission, distribution, and power supply in the power system. Generally, the current passing through power cables is relatively large; communication cables refer to a type of cable used to transmit signals. This includes transmitting audio, digital and analo...
