Protect halogen-free and low-smoke flame-retardant polyolefin, meet the requirements such as RoHS；Under flame condition, the first sealing coat and restrictive coating can disappear, will not
Producing toxic smoke, ceramic fireproof composite band can be converted into sintering pottery, jointly plays insulating effect with gold mica tape, fire prevention
Layer is also converted to have heat insulation, fire prevention, waterproof porcelain tube, even if in also can guarantee that cable under conditions of flame temperature 950 DEG C
The temperature in portion, especially aluminum pipe is less than 600 DEG C, and aluminum pipe will not be melted, and also has certain anticollision effect simultaneously, these
Jointly guarantee that cable normally can use in certain time；It addition, seamless aluminium tubing has the effect of armouring, shielding, earth lead, this electricity
Cable, after by flame calcination, is immersed in the water and still can normally use a period of time；Make owing to have employed composite ceramic soil material
Fireprotection layer, under Fire Conditions, the conductor wire core of cable can be pacified in, fireproof porcelain tube heat insulation having of being formed by fireprotection layer
So work so that this cable, while conformance with standard BS 6387-1994, also can meet up-to-date fire-protection standard BS 8491-
The requirement of 2008 and BS 6387-2013, i.e. remains to bear combustion in 2 hours at 830～870 DEG C under load 0.6/1kV working condition
Burning, fire duration 10min starts impact, impacts once every 10min, 5min before off-test, starts water spray, sprays every 60s
Once, spray water water persistent period 5s every time, can keep normal work.

Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the aluminium sheath of the present invention extrudes mineral insulated cable continuously, including the line of many mutually insulateds
Core, each core includes the first sealing coat 1, mineral insulation the 2, second sealing coat 3 and conductor bundle 4, each core the most successively
All it is wrapped in same restrictive coating 8, in the gap between restrictive coating 8 and each core, is filled with fireprotection layer 7, fireprotection layer 7 outer wrapping
Non-woven fabrics 9, non-woven fabrics 9 is had to be wrapped with restrictive coating 8.
Preferably, the first sealing coat 1 is ceramic fireproof composite band.
Preferably, mineral insulation 2 is ceramic fireproof composite band and gold mica tape.
Preferably, the second sealing coat 3 is crosslinked polyethylene.
Preferably, conductor bundle 4 is copper conductor.
Preferably, metal level 6 is seamless aluminium sheath, and seamless aluminium sheath is isolated by band, and band is pottery chemoprevention
The fire-resistant composite band of fire.
Preferably, restrictive coating 8 is halogen-free and low-smoke flame-retardant polyolefin.
Preferably, fireprotection layer 7 is made up of the composite ceramic soil material as primary raw material with magnesium hydroxide or aluminium hydroxide.
Preferably, fire-resistant inserts 5 is Halogen packing.
This exemplary fiber optic cable as shown in Figure 1 is quad, and the sectional area of three phase lines and a center line is 6mm,
Voltage specification 0.6/1kV, its manufacturing process flow is as follows, and every procedure is all tested after terminating, and checks under qualified just entrance
Procedure:
。
Under normal usage, mineral insulation 2 and the second sealing coat 3 all have well insulation to the cable of the present invention
Effect, the second sealing coat 3 can prevent in fireprotection layer the composite ceramic soil material as primary raw material with magnesium hydroxide or aluminium hydroxide
In a small amount of moisture on the gold mica tape in mineral insulation 2 and the impact of the insulating properties of ceramic fireproof composite band.
Seamless aluminium sheath 6, such as aluminum pipe, has pliable and tough and armouring effect concurrently, can keep the flexibility that cable is good, also can increase the whole of cable
Body mechanical performance, make cable have under flame condition the most waterproof, fire prevention, anticollision effect；When normally using, cable is whole
Body has good flexibility, and fireprotection layer 7, in thickness muddy, is conveniently processed, and cable length can be not limited, but when long
Between contact under air conditions, fireprotection layer 7 will slowly harden, thus loses flexibility；The material of restrictive coating 8 is the low cigarette of environment friendly non-halogen
Fire retardant polyolefin, meets the requirements such as RoHS；Under flame condition, the first sealing coat 1 and restrictive coating 8 can disappear, and will not produce toxic smoke,
Ceramic fireproof composite band can be converted into sintering pottery, jointly plays insulating effect with gold mica tape, and fireprotection layer 7 also converts
For there is heat insulation, fire prevention, waterproof porcelain tube, even if also can guarantee that inside cable, especially under conditions of flame temperature 950 DEG C
The temperature of aluminum pipe is less than 600 DEG C, also has certain anticollision effect simultaneously, and these guarantee that cable can be in the short time jointly
Normal use；It addition, seamless aluminium tubing 6 has the effect of armouring, shielding, earth lead, this cable, after by flame calcination, is immersed in the water
Still a period of time can normally be used；It is made for fireprotection layer 7, cable under Fire Conditions owing to have employed composite ceramic soil material
Conductor wire core can work in, fireproof porcelain tube heat insulation having of being formed by fireprotection layer 7 safely so that this cable is meeting mark
While quasi-BS 6387-1994, also can meet up-to-date fire-protection standard BS 8491-2008 and the requirement of BS 6387-2013, i.e.
Remaining to bear burning in 2 hours at 830～870 DEG C under load 0.6/1kV working condition, fire duration 10min starts impact, often
Impact once every 10min, 5min before off-test, start water spray, spray water once every 60s, every time water spray persistent period 5s, energy
Keep normal work.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff is complete
Entirely can carry out various change and amendment in the range of without departing from this invention technological thought.The technology of this invention
