Problems solved by technology
[0002] Flame-retardant and halogen-free materials do not volatilize and do not produce corrosive gases when burned. They are called pollution-free flame retardants. Due to the complex application scenarios of cables, they may cause fires caused by lightning strikes or long-term work during outdoor installation. If the temperature is too high and a fire occurs, if the fire is not timely, it is easy to cause a fire and damage property safety; because the power cable itself is soft and easy to twist, it will be damaged and broken when twisted in a high temperature environment, resulting in the exposure of the wire core, causing fire or electric shock and other problems.

Embodiment Construction
[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below in conjunction with the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention. Not all, based on this embodiment, other embodiments obtained by those skilled in the art without creative efforts are all within the protection scope of the present invention.
[0033] Such as Figure 1 to Figure 5 As shown, the high flame-retardant halogen-free power cable includes a No. 1 wire core 2 and a number of No. 2 wire cores 3 distributed around the No. 1 wire core 2 in a circle. There is a halogen-free flame-retardant layer 4 in between, and a waterproof layer 5 is arranged outside the halogen-free flame-retardant layer 4. The waterproof layer 5 is equipped with a high flame-retardant low-smoke halogen-free outer cover 6, and the ...

The invention relates to a high flame-retardant halogen-free power cable and a wire take-up device after preparation thereof, wherein the cable includes a No. 1 wire core and several No. 2 wire cores distributed around the No. There is a halogen-free flame-retardant layer between the wire cores, and a waterproof layer is provided outside the halogen-free flame-retardant layer. There is an insulating layer; the high flame-retardant low-smoke and halogen-free outer cover is equipped with several anti-torsion units that prevent the high flame-resistant low-smoke and halogen-free outer cover from being twisted by external force. In the present invention, the torsion-resistant block is combined by reinforcing ribs, which can prevent the cable from twisting around the axis and increase the strength of the high flame-retardant, low-smoke, halogen-free cover; the present invention drives molds with different apertures to cooperate with cables through the No. Diameter cables are thermally formed, and at the same time, the No. 2 lead screw drives the lifting frame to go up and down so that the No. 1 guide wheel drives the cables to be distributed on the reel.
Description
technical field [0001] The invention relates to the field of cable production and manufacturing, in particular to a high flame-retardant halogen-free power cable and a prepared wire take-up device. Background technique [0002] Flame-retardant and halogen-free materials do not volatilize and do not produce corrosive gases when burned. They are called pollution-free flame retardants. Due to the complex application scenarios of cables, they may cause fires caused by lightning strikes or long-term work during outdoor installation. If the temperature is too high and a fire occurs, if the fire is not timely, it is easy to cause a fire and damage property safety; because the power cable itself is soft and easy to twist, it will be damaged and broken when twisted in a high temperature environment, resulting in the exposure of the wire core, causing fire or electric shock and other problems. .
