For solving the technical problem, the utility model provides a fire-retardant type comprehensive monitoring cable, including oversheath, signal line, video line, control line, copper wire, its characterized in that, in the oversheath was located respectively to signal line, video line, control line, copper wire, the copper wire is equipped with two, is located the both sides of signal line respectively, the signal line has wrapped up in proper order by inside to outside has first insulation layer, first shielding layer, first fire-retardant layer, first inner sheath, it has the fire-retardant layer of second insulation layer and second to wrap up in proper order on the video line, it has the fire-retardant layer of third insulation layer and third to wrap up in proper order on the control line.

Furthermore, the outer sheath also comprises a filling layer, the filling layer is arranged in a gap in the outer sheath and used for fixing the relative position of the cable, and the filling layer is a filler made of a flame-retardant material.

Furthermore, the signal line is respectively arranged in parallel with the video line, the control line and the steel wire, the diameter of the signal line is 2.8mm, the diameters of the video line and the control line are both 2.5 mm, and the diameter of the steel wire is 2.2 mm.

Furthermore, one steel wire is positioned between the signal wire and the video wire, the other steel wire is positioned between the signal wire and the control wire, and a layer of zinc is plated on each of the two steel wires.

Furthermore, the first flame-retardant layer, the second flame-retardant layer and the third flame-retardant layer are all made of glass fiber materials.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the parcel has fire-retardant layer respectively on signal line, video line and control line, and still includes the filling layer that adopts fire-retardant material to make in the outer jacket, consequently can effectively strengthen the flame retardant property of cable.
