Abstract
The utility model provides a warp-resistant flexible insulating environment-friendly fireproof cable. The cable comprises four conductors and an optical fiber conductor. The conductor is composed of a wire, and a wrapping layer and a first insulating layer which coat the conductor in sequence. The optical fiber conductor is composed of an optical fiber wire, and a second insulating layer, a shielding layer and a third insulating layer which coat the optical fiber wire in sequence. The four conductors are parallelly arranged in a rhombus pattern along the length direction of the cable. The optical fiber conductor is arranged at the center position of the four conductors. Gaps among the four conductors and the optical fiber conductors are filled with waterproof filling material such that a cable core with a round cross section is formed. The cable core is sequentially coated by a heat-insulating liner layer, an elastic metal pipe sheath, a cross-braided inner sheath, a double-layer fireproof tape layer and an outer sheath. The warp-resistant flexible insulating environment-friendly fireproof cable provided by the utility model solves the problems that the conventional cable has insufficient warp-resistant capability and poor fireproof performance.

Background technology
Fire-resisting cable is widely used and the intensive market of personnel, the place such as skyscraper, hospital, cinema, hotel, public place of entertainment, underground railway, undergrond street, large-scale power station and important industrial and mining enterprises.Traditional fire-resisting cable structure is simple, use not environmental protection of material, cable fire performance is not ideal enough, while causing breaking out of fire, occur core short circuit phenomenon, or the flue gas producing because of cable self burning happens occasionally to phenomenons such as human body damage.
In the time there is fire, fire-resisting cable should be appointed and can be maintained a period of time as power transmission lines or infor-mation-carrying wire road, can win the time of more suing and labouring for the transfer of fire-extinguishing and lifesaving, data message on the one hand, effectively reduce the injury that flue gas that cable burning itself produces causes human body because cable material is not halogen-containing on the other hand, thereby reduced disaster-stricken loss and personnel's injures and deaths.Therefore, a kind of more high-performance environment protection type fire-resisting cable of long running time that can maintain in flame combustion is subject to user's trust very much, is also the inevitable choice of hommization society.
The employing that traditional cable is more the poor not flame resistant of structure of thermal insulation.Therefore; in the time of breaking out of fire; the not flame resistant baking of this class cable; be difficult to isolated flame; therefore flame is easy to these protective layers of ablation, makes cable directly be subject to the calcination of flame, causes cable can not work because of short circuit; and the anti-twist scarce capacity of common cable, is subject to distortion to affect the useful life that also can shorten cable for a long time.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of warp resistance flexible insulation environment-friendly type fire-resisting cable, solve the anti-twist scarce capacity of existing cable, the problem that fire resistance is not good.
A kind of warp resistance flexible insulation environment-friendly type fire-resisting cable the utility model proposes, comprise four conductors and a conductor fiber, described conductor by wire and the lapping layer and the first insulating barrier that are coated on successively outside wire form, described conductor fiber is by the second insulating barrier outside optic fibre wire and clad optical fiber wire, screen and the 3rd insulating barrier form, described four conductors are along the cable length direction layout that is parallel to each other and assumes diamond in shape, described conductor fiber is located at the center of described four conductors, between described four conductors and described conductor fiber, filling the packing material formation cross section that blocks water is circular cable core, be coated successively insulating inner lining layer outward at described cable core, elastic metallic tube boot, interlacing inner sheath, double-deck fire-resistant belt and oversheath.
Preferably, described conductor fiber is with circumscribed in two described conductors at rhombus minor axis two ends.
Preferably, inner sheath adopts silicon rubber to make.
Preferably, double-deck fire-resistant belt adopts the wrapped formation of double-deck fire-resistant isinglass belt.
Preferably, oversheath adopts silicon rubber to make.
Warp resistance flexible insulation environment-friendly type fire-resisting cable of the present utility model, insulating inner lining layer is set, improve the fire resistance of cable, extended cable normal working hours in flame combustion, reduced the injury that the flue gas that produces because of cable burning itself causes human body; Adopt elastic metallic pipe to make metallic sheath, have good bendability and flexibility; Inner sheath adopts the design of interlacing, and interlacing structure has larger extending space, has effectively promoted the anti-twist ability of cable, has extended the useful life of cable; Double-deck fire-resistant belt is set, has effectively promoted the fire-resistance property of cable, can stand for a long time the flame temperature of nearly 800 DEG C, ensured the use safety of cable; This cable not only can conduct electricity, and can also realize optical fiber communication.
