Specific embodiment

Below in conjunction with the accompanying drawings, the utility model is further described.

Embodiment one, referring to shown in Fig. 1, it includes seven fire-proof insulation cores 1 and armor 8；Seven fire-proof insulation lines Arranged tangential and it is arranged on inside armor 8 between the surface of core 1；Filler is provided between seven outer surfaces of fire-proof insulation core 1 5；Thermal insulation layer 6 and tensile layer 7 are provided between armor 8 and seven outer surfaces of fire-proof insulation core 1；Fire-proof insulation core 1 from Include metallic conductor 2, mica insulation layer 3 and insulating protective layer 4 successively from inside to outside；Metallic conductor 2 is copper conductor；Copper conductor is by one Bar or a plurality of copper conductor is stranded forms, a plurality of copper conductor cross section is circle, reduces the contact area of twisted copper conductors, reduces resistance It is anti-；Mica insulation layer 3 is at least using six layers of winding copper conductor；The insulaion resistance of mica insulation layer 3 is big, good insulating, high temperature resistant 1200 DEG C, the validity of control cable copper conductor insulating barrier insulating properties when melting below total is protected, while improve product making The conductor operating temperature of used time, improves the combined closure system of product；Insulating protective layer 4 is low-smoke halogen-free polyolefin protective case, protects cloud The integrality of female insulating barrier 3, plays waterproof and dampproof effect, while increasing the service life of fire-proof insulation core.

Armor 8 hands over button armouring set for interlocking S-shaped, and the outer surface of armor 8 is shape of threads, and its inner surface is round and smooth spiral shell Line shape；Armor 8 adopts galvanized steel material, and galvanized steel is molten always more than 1500 DEG C；Armor 8 makes the utility model profile in circle Shape and reduce the bending radius of cable, it is easy for installation acted on by external force after do not allow it is yielding, simultaneously because adding tension Layer, tensile property is strengthened, and will not produce after external force effect makes armouring metal edge of a knife shape sheet metal occur, will not be to control Cable processed causes to damage, and increases the life-span of control cable, and energy digital preservation control cable occurs steel sheath lock armo during fire Toxic gas will not be discharged, the light transmittance after burning is higher than 80% or higher；Armor 8 can effectively completely cut off naked light to control electricity The calcination of cable internal structure, only hot gas can be entered inside control cable, then through the protection of thermal insulation layer 6, hot gas reaches mica Much less than 1000 DEG C during insulating barrier 3, can guarantee that mica insulation layer 3 will not deform, it is ensured that insulating properties validity.

Tensile layer 7 is that tension aluminium foil wheat draws layer, with pull resistance, makes the anti-weight jolt capacity of armor 8 strong；There is fire House caves in and easily causes the drawing of pulling of control cable during calamity, and wheat draws aluminium foil to serve good drawing-resistant function.

Thermal insulation layer 6 is 125 ° of low-smoke halogen-free polyolefin layers, for fire-proof insulation core 1 to be opened with external heat air bound, is played Fire prevention, the effect of insulating water-proof.In case of fire, when environment temperature is up to more than 650 DEG C, this thermal insulation layer carbonization, in metal armour Under the protection of dress layer 8, thermal insulation layer 6 can fix control cable after being carbonized, and effectively open fire-proof insulation core and external heat air bound, The integrality and insulating properties of protection mica insulation layer 3 are played, protection control cable is not short-circuit, not breaking, so as to ensure circuit Unimpeded, thermal insulation layer 6 can effectively completely cut off core heat, reduce sheath temperature, when the operating temperature of fire-proof insulation core 1 is 125 DEG C, Within 75 DEG C, when operating temperature is 150 DEG C, outer jacket temperature is within 88 DEG C for outer jacket temperature.

Filler 5 adopts glass-fibre fillers, and glass fibre does not fire, and anti-corruption is heat-insulated, and isolation is good, tensile strength Height, the good characteristic of electrical insulation capability, in fire hazard environment will not acoustic product fire performance.

Control cable in embodiment one is usable in nuclear power, mine, petrochemical industry, ships, mass merchandiser, high level and builds Build, subway, airport, school, hospital, people's intensity office space etc., the indoor control in the field for paying much attention to fire-fighting fire-proof Wiring is used.

Referring to shown in Fig. 2, the outer surface of armor 8 is provided with external protection 9；Described external protection 9 is poly- for low smoke and zero halogen Second hydrocarbon protective case；Increasing external protection coating 9 can be increased the service life of product and is improved the water proofing property of product with digital preservation cable Can, it is mainly used in outdoor laid and uses.

The above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover in the middle of right of the present utility model.
