Embodiment Construction
[0009] like figure 1 As shown, an armored fireproof cable includes an insulated wire core composed of a conductor 1 and an insulating layer 2 coated on the outside of the conductor, a copper wire shielding layer 3 covering the insulated wire core, and an inner sheath outside the copper wire shielding layer 3 Steel wire armor layer 5 outside layer 4 and inner sheath layer 4. A mica filling tape 6 is provided between the copper wire shielding layer 3 and the inner sheath layer 4, and the copper wire shielding layer 3 is a braided copper wire mesh. The inner sheath layer 4 is chlorosulfonated polyethylene.

The invention relates to an armored fireproof cable. The armored fireproof cable comprises an insulating wire core composed of conductors and insulating layers for wrapping the outside of the corresponding conductors, and a copper wire shielding layer which wraps the insulating wire cores, an inner sheath layer outside the copper wire shielding layer, and a steel wire armor layer outside the innersheath layer. The armored fireproof cable is reasonable in design, simple in structure and high in fire resistance, and the circuit can still be kept unblocked in the fire scene, and the power supplyand the information can be normally transmitted.
Description
technical field [0001] The invention relates to a cable, in particular to an armored fireproof cable. Background technique [0002] As an important information transmission medium, cables have attracted much attention for their safety performance. It is difficult for existing cables to ensure smooth lines in a fire scene, and they may even burn too much, endangering safety. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the purpose of the invention is to provide an armored fireproof cable. [0004] Technical solution: An armored fireproof cable, including an insulated wire core composed of a conductor and an insulating layer coated on the outside of the conductor, a copper wire shielding layer covering the insulated wire core, an inner sheath layer outside the copper wire shielding layer, and an inner sheath Steel wire armor outside the jacket. [0005] A mica filling tape is arranged between the copper wire shie...
