Problems solved by technology
When the wires and cables are burned, a large amount of thick smoke will be emitted, accompanied by a large amount of toxic gas, which provides deeper protection for the burning objects in hidden places, and causes great harm to the human body and the environment.
And when a fire broke out in the past, the people who escaped could not tell the direction and panicked, prolonging the time of staying in the fire scene

The invention discloses a fireproof and flame-retardant flexible cable for computer control. The fireproof and flame-retardant flexible cable comprises a cable core, a shielding layer, a flame-retardant layer and a corrosion prevention layer, wherein the cable core comprises cable conductors, an insulation layer, a filling layer, a fixing frame and filling ropes, the insulation layer is arranged outside the cable conductors in an extruded manner, the filling layer is arranged outside the insulation layer in an extruded manner, a buffer layer is arranged outside the filling layer in an extruded manner, the radial fixing frame is arranged in the filling layer between the insulation layer and the buffer layer and comprises five same support rods, an armoring layer is arranged outside the buffer layer in an extruded manner, an oxygen isolation layer is arranged outside the armoring layer in an extruded manner, the shielding layer is arranged outside the oxygen isolation layer in an extruded manner, four same ground lines are arranged in the shielding layer, a flame-retardant layer is arranged outside the shielding layer in an extruded manner, and the corrosion prevention layer is arranged outside the flame-retardant layer in an extruded manner. The fireproof and flame-retardant flexible cable has the characteristics of a novel and firm structure, stable signal transmission, good pressure-resistant buffer effect and the like, so that the cable is longer in service lifetime.
Description
technical field [0001] The invention relates to the field of cable manufacturing, in particular to a fire-resistant and flame-retardant flexible cable for computer control. Background technique [0002] 60% of the fires are caused by electrical lines, whether it is the fire caused by the wires and cables themselves or the combustion caused by an external fire source, because the wires and cables laid in the electrical shaft or trunking are often laid in bundles, the heat generated during combustion The radiation will conduct each other again, causing the fire to spread and flood. When the wires and cables are burned, a large amount of thick smoke will be emitted, accompanied by a large amount of toxic gas, which provides deeper protection for the burning objects in hidden places, and causes great harm to the human body and the environment. And the people who escaped when a fire broke out in the past can't tell the direction and panic, and prolong the time of staying in the ...
