Environment-friendly cable for safety fire protection

Abstract

The invention relates to an environment-friendly cable for safety fire protection, which comprises a plurality of conductors. An insulating layer is extruded outside the conductor to form an insulating wire core; a temperature sensing wire is arranged between the insulating wire cores at intervals; a flame-retardant filling layer is arranged outside the insulating wire core; a wrapping layer, a ceramic silicone rubber layer, an aluminum alloy tape armor and a sheath are sequentially arranged outside the flame-retardant filling layer; when the cable passes through a fire scene or is in a complex high-heat environment in the operation process, the cable may be locally heated, heat is transferred to a temperature sensing wire in the center; when the temperature sensing wire reaches a set threshold value, the temperature sensing wire is fused, at the moment, normal operation of the cable is not affected, but the power monitoring part is reminded, so that the high-temperature point of the cable can be known, cooling treatment can be carried out in time, the spontaneous combustion problem caused by over-high temperature of the conductor can be well avoided, fireproof materials used outside the insulating wire cores are environment-friendly materials, and the quality of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to an environment-friendly cable for safety and fire protection. Background technique [0002] With my country's economic development, modernization construction, and industrialization progress, the requirements for the technical level of industrial equipment are getting higher and higher. Now commonly used insulating materials are organic materials, which are easy to release a large amount of toxic gas and smoke in case of fire. In addition, cables are usually located in relatively hidden places, which aggravates the difficulty of rescue, and it is difficult to ensure that some important electrical circuits are normally carried out during a fire. Therefore, there is a need for a fireproof cable that can prevent fire and control toxic gas and smoke. In order to solve this problem, inorganic insulating materials are usually used to produce cables. [0003] Especially in ...

Problems solved by technology

Now commonly used insulating materials are organic materials, which are easy to release a large amount of toxic gas and smoke in case of fire. In addition, cables are usually located in relatively hidden places, which aggravates the difficulty of rescue, and it is difficult to ensure that some important electrical circuits are normally carried out during a fire. Therefore, there is a need for a fireproof cable that can prevent fire and control toxic gas and smoke. To solve this problem, inorganic insulating materials are usually used to produce cables

[0003] Especially in densely populated places, such as residential buildings and shopping malls, the cables are distributed more and densely. During the peak period of electricity consumption, the cables are often overloaded, which makes the temperature of the cables too high and prone to spontaneous combustion. It is difficult to predict. For the safety of electricity, the current cables usually use various fireproof materials to achieve flame retardant effects, but the problem of spontaneous combustion of cables cannot be solved well, so a new safety performance is needed Environmentally friendly cables for higher safety fire protection
