Supply line can power within the regular hour when guarantee is caught fire, and be easy to the evacuation of personnel and valuable cargo.But the system of the cable
Make technique cumbersome, equipment investment is big.Drum length of cable is limited, and such as lays over long distances, it is necessary to increase transition joint.And it is middle
The increase of joint, will certainly increase the possibility of product gas leakage.The easy moisture absorption of magnesia powder, causes cable in joint after the moisture absorption
Insulaion resistance declines, and influences electric property.In addition, the bending property of cable is poor, mounting and installation inconvenience is subject to one using scope
Definite limitation.Because manufacturing process is complicated, high energy consumption, finished product rate is low, causes cable price high, and the popularization for being not easy to product makes
With.
The content of the invention
The purpose of this utility model is just being directed to above-mentioned prior art problem, there is provided a kind of humidity resistance is good, fire prevention, fire resisting
Property good, good bandability, anticorrosive property is good, mounting and installation is convenient, low cost, can greatly specification production a kind of composite isolated apply
The flexible cable of material.
A kind of flexible cable of composite isolated coating of the utility model, it is characterised in that：The cable includes many
By conductor（1）, insulating barrier（2）, insulated damp-proof layer（3）, glass fiber layer of cloth（4）The cable core of composition be wrapped in cable core
Outer glass cloth belt（6）, oxygen barrier layer（7）, metal sheath layer（8）, external sheath layer（9）Combine, it is described, in glass cloth tape
Layer（6）Separation layer and cable core between（5）With oxygen barrier layer（7）Using oxygen index (OI) >=35% Halogen, low-smoke and flame retardant material.
Further, the flexible cable conductor of described a kind of composite isolated coating（1）Twisted using heat-resisting aluminium alloy
Line.
Further, described heat-resisting aluminium alloy twisted wire is formed with heat-resisting aluminium alloy round wires and galvanized steel wire are stranded.Its
Cross sectional shape is circular configuration.This structure is easy to process, and factory length is unrestricted, when using with certain flexibility and
Bendability, is easy to lay.
Further, the flexible cable separation layer of described a kind of composite isolated coating（5）With oxygen barrier layer（7）Using
The Halogen of oxygen index (OI) >=40%, low-smoke and flame retardant material are the compound potter's clay of the mineral matter of easy-sintering.The work for preventing moisture from invading can be played
With.
Further, described glass cloth belt（6）Formed using unorganic glass silk fiber woven cloth band is wrapped, this knot
Structure may also function as tight bundle and heat-blocking action.
Further, the protective metal shell described in the utility model uses stainless steel embossing structure.
The utility model has the beneficial effect that compared with traditional fireproof cable：Factory length is long, transition joint is few, installation side
Just, fault rate can be effectively reduced, fire protecting performance is excellent, 950 DEG C, the combustion test of 3 hours can be born in the case of powered, and
Ensure the normal operation of circuit, temperature resistant grade is high, transmission capacity is big, moisture effect is good, with anti-corrosion function, mechanical performance
Good, performance is fully achieved the standard requirement of mineral insulated cable.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
（1）Conductor,（2）Insulating barrier,（3）Insulated damp-proof layer,（4）Glass fiber layer of cloth,（5）Separation layer,（6）Glass cloth tape
