Further improvement of the present invention is: the conductor in insulation cable core is annealed copper conductor, and this conductor not only conducts electricity very well but also burns because self-characteristic can effectively stop conductor.
Further improvement of the present invention is: insulation is filled with fire-retardant nylon layer between cable core gap, and this design can effectively prevent because of other cable of the related burning of ignition of cable.
Further improvement of the present invention is: insulating barrier adopts cross-linking polyethylene materials suit to form, and due to this material behavior, to be that insulating barrier has high temperature resistant, anticorrosive, good insulating, wear-resistant, ampacity discharge toxic gas greatly and not and reduce costs, be convenient to the function of transportation.
Further improvement of the present invention is: cable conductor is wrapped up by three layers of fireproof mica layer, and this design can utilize the characteristic of fireproof mica layer to the full extent, stops flame combustion cable.
Further improvement of the present invention is: screen is aluminum alloy sleeve tubular construction, utilizes the shielding character of aluminium alloy sleeve pipe to reduce the interference of outside electric wave to cable.
Further improvement of the present invention is: sheath adopts the wrapped formation of fire-resistant isinglass belt, prevents that outside combustibles from entering.
Further improvement of the present invention is: armour is the wrapped overcoat of double-layer stainless steel steel band, can effectively keep out the damage of exterior object to cable.
Further improvement of the present invention is also: to be that crosslinked polyethylene sheath is wrapped form fire-retardant outer jacket, not only can stop combustibles burning cable also can stop the pernicious gas producing because of burning to overflow, and increases the service life.
The invention has the beneficial effects as follows: 1. fire resistance is excellent.2. firm in structure.3. long service life.4. shield effectiveness is good.5. insulating properties is good.6. safety and environmental protection, reduces costs.

Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
The present embodiment is as illustrated in figs. 1 and 2: a kind of novel cross-linking polytene insulation control cable, this cable comprises ten strand insulation cable cores 1, described insulation cable core 1 is followed successively by from inside to outside after cable conductor 8, fireproof mica layer 9 and insulating barrier 10, ten strand insulation cable cores 1 are twisted into rope bundle and wraps up successively from inside to outside fire-retardant belting layer 3, screen 4, sheath 5, armour 6 and fire-retardant outer jacket 7; Cable conductor 8 in described insulation cable core 1 is annealed copper conductor, described insulation cable core is filled with fire-retardant nylon layer 2 between 1 gap, described cable conductor 8 is by three layers of fireproof mica layer, 9 parcel, described thickness of insulating layer is 1cm, described screen 4 is aluminum alloy sleeve tubular construction, described sheath 5 adopts the wrapped formation of fire-resistant isinglass belt, and described armour 6 is double-layer stainless steel steel band, and described fire-retardant outer jacket 7 forms for crosslinked polyethylene sheath is wrapped.
The present invention in use, works as breaking out of fire, because fire-retardant outer jacket 7 forms for crosslinked polyethylene sheath is wrapped, can effectively stop burning to be invaded from outside, and when inside cable burns, also can stop toxic gas to overflow from inside; Fire-retardant outer jacket 7 the inside one decks are armour 6, described armour 6 is double-layer stainless steel steel band, this armour 6 can effectively be kept out the destruction of something outside, as shock, mouse ant bait, armour 6 the inside one decks are sheath 5, and described sheath 5 adopts the wrapped formation of fire-resistant isinglass belt, because fireproof mica material self-characteristic is exactly good fire-retardant body, therefore when sheath 5 is invaded in burning, sheath 5 can stop fire spreading preferably; Sheath the inside one deck is screen 4, described screen 4 is aluminum alloy sleeve tubular construction, utilize the shielding character of aluminium alloy sleeve pipe to reduce the interference of outside electric wave to cable, screen 4 the inside one decks are insulating barrier 10, insulating layer material 10 is crosslinked polyethylene, thickness is 1cm, and due to this material behavior, to be that insulating barrier has high temperature resistant, anticorrosive, good insulating, the wear-resistant and function that do not discharge toxic gas, and use cost is low is convenient to transportation; Insulating barrier 10 the inside one decks are ten strand insulation cable cores 1, between insulation cable core 1, fill fire-retardant nylon layer 2, effectively prevent because of other cable of the related burning of ignition of cable; In insulation cable core 1, comprise fireproof mica layer 9 and cable conductor 8, three layers of fireproof mica layer 9 can effectively protect burning under emergency case and injure cable conductor 8, and cable conductor 8 is annealed copper conductor, because possessing flame-retarding characteristic through special processing, therefore form last fire-retardant defence line together, ensure and produce and personal safety.
