Embodiment 1

[0034] refer to figure 1 , the embodiment of the present invention provides a cable, the cable includes a wire 101, a high temperature resistant insulating layer 102, a shielding layer 103 and a protective layer 104, the shielding layer 103 and the protective layer 104 are both hollow structures, and the high temperature resistant insulating layer 102 wraps Outside the wire 101, the shielding layer 103 is wrapped around the high temperature resistant insulating layer 102, and the protective layer 104 is wrapped around the shielding layer 103, and the surface of the protective layer 104 is provided with a thermosensitive discoloration layer 105 that can change color according to temperature.

[0035] The high-temperature-resistant insulating layer 102 has good high-temperature resistance and insulation performance, so it can have a good insulating effect. When the wire 101 is energized and heated, it will not be melted by the heating wire 101, and it is not easy to be broken dow...

Embodiment 2

[0042] refer to figure 2 , the embodiment of the present invention provides a cable, the cable includes a wire 101, a high temperature resistant insulating layer 102, a shielding layer 103 and a protective layer 104, the shielding layer 103 and the protective layer 104 are both hollow structures, and the high temperature resistant insulating layer 102 wraps Outside the wire 101, the shielding layer 103 is wrapped around the high temperature resistant insulating layer 102, and the protective layer 104 is wrapped around the shielding layer 103, and the surface of the protective layer 104 is provided with a thermosensitive discoloration layer 105 that can change color according to temperature.

[0043] The wire 101 is formed by twisting multiple copper wires with good oxidation and corrosion resistance.

[0044] The high temperature resistant insulation layer 102 is made of dimethyl silicone rubber with good high temperature resistance and insulation properties.

Abstract

The invention provides a cable and relates to the field of power cables. The cable comprises a wire, a high-temperature-resistant insulated layer, a shielding layer, and a protective layer. The high-temperature-resistant insulated layer, the shielding layer, and the protective layer are all hollow structures. The high-temperature-resistant insulated layer wraps the wire. The shielding layer wraps the high-temperature-resistant insulated layer. The protective layer wraps the shielding layer. The outer surface of the protective layer is equipped with a temperature-sensitive variable-color layer. The cable is not liable to soften and is good in signal shielding effect. The temperature of the outer surface of the wire can be conveniently known and the use safety of the cable is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a cable. Background technique [0002] In winter, places such as homes or public shopping malls are usually designed with floor heating for heating. The heat source is radiated from the ground to the indoor space to achieve the effect of heating. Floor heating is divided into water heating and electric heating according to power. Water heating is to lay special pipes under the floor, and circulate hot water not exceeding 60 degrees in the pipes to heat the ground and radiate into the space; electric heating is special cable laying Underground, the ground is heated by the heat generated by the cable itself. [0003] The safety of the cables used for floor heating is the most important during use. However, in the process of using cables for heating, it is easy to cause the cables to overheat due to circuit failure or other reasons. There is no safety guarantee, and safety accidents are...
