Problems solved by technology

[0002] The signal cable in the prior art has poor high temperature resistance, and the signal cable has poor flexibility and cannot be bent, otherwise the outer cover will be easily damaged
In addition, when the signal cable is used for long-distance transmission, the signal anti-interference ability of the signal cable is poor, and the signal attenuation of the signal cable is very serious, which affects the quality of signal transmission. Therefore, there is a need for improvement in the signal cable of the prior art
[0003] At present, many cable workers have single functions and poor signal guarantee effect, so it is of great practical significance to design a signal high-fidelity fireproof shielding cable

Embodiment 1

[0020] Such as figure 1 As shown, this embodiment provides a signal high-fidelity fireproof shielded cable, which is characterized in that it includes multiple sets of cable cores 2, the multiple sets of cable cores 2 are wrapped with polyester tapes 4 in turn, and the polyester tapes 4 are wrapped with polyester tapes in turn Inner shielding layer 5, anti-corrosion layer 6, flame retardant layer 7, copper braided outer shielding layer 8 and outer sheath layer 9, said copper braided outer shielding layer 8 has a plurality of tearing ropes 1 evenly distributed on the circumference, each The cable core wires 2 each include a conductor and a conductor shielding layer, an XLPE insulating layer, an insulating shielding layer and a loose sleeve layer wrapped around the conductor in sequence.

[0021] A water-blocking layer 10 is also provided between the flame-retardant layer 7 and the copper braided outer shielding layer 8, and the water-blocking layer 10 includes a dry filler laye...

Embodiment 2

[0025] This embodiment is further optimized on the basis of embodiment 1, specifically:

[0026] The conductor is a galvanized conductor with a circular or rectangular cross section, and the sectional area of ​​the galvanized conductor is 1.2-1.6 mm.

[0027] The material of the outer sheath layer 9 is magnesium chloride insulating material.

[0028] The flame-retardant layer 7 is a fire-resistant water-blocking tape, and the flame-retardant layer 7 includes a mica layer. The two sides of the mica layer are respectively bonded with a reinforcing layer made of glass fiber mesh, and a layer of water-blocking powder is bonded on the reinforcing layer. The thin film forms a water-blocking layer.

[0029] The outer sheath layer 9 is a sheath of high oxygen index cross-linked polyethylene material.

Abstract

The present invention discloses a signal high-fidelity fireproofing shielding cable, and relates to the technical field of cables. The technical problems are solved that general shielding is poor anda fireproofing performance is poor. The cable comprises a multi-group cable cores which are coated with polyester tapes in order, the polyester tapes are coated with an inner shielding layer, an anticorrosive coating, an inflaming retarding layer, a copper weaving outer shielding layer and an outer sheath in order, multiple tearing ropes are uniformly distributed in the copper weaving outer shielding layer, and each cable core wire comprises one conductor and one conductor shielding layer, one XLPE insulation layer, one insulation shielding layer and one lapped joint layer coating the outer portion of the conductor in order. Compared to a general cable, the signal high-fidelity fireproofing shielding cable is simple in structure and good in shielding effect and facilitates data and signaltransmission.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to a signal high-fidelity fireproof shielded cable. Background technique [0002] The signal cable in the prior art has poor high temperature resistance, and the signal cable has poor flexibility and cannot be bent, otherwise the outer cover will be easily damaged. In addition, when the signal cable is used for long-distance transmission, the signal anti-interference ability of the signal cable is poor, and the signal attenuation of the signal cable is very serious, which affects the quality of signal transmission. Therefore, there is a need for improvement of the signal cable in the prior art. [0003] At present, many cable workers have single functions and poor signal guarantee effect, so it is of great practical significance to design a signal high-fidelity fireproof shielded cable. Contents of the invention [0004] The invention overcomes the above-mentioned technical ...
