Description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and examples：

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

As shown in Figure 1, a kind of integrate waterproof, fire resisting, the halogen-free low-smoke high-flame shielded flexible cable of flame retarding function, bag Multiple conductive units are included, the conductive unit includes conductor 1, filled with water blocking yarn 2 in the monofilament of conductor 1, in the outer of conductor 1 Portion is coated with flame retardant coating 3 and insulating layer 4 successively；The conductive unit can be 2,3 or 4.The conductor 1 uses high-purity Oxygen-free copper, it is per share to have several conductor monofilament if every layer has carried interest if conductor wire core can have dried layer, and be in bundle strand structure, In the structure that tangles again between stock and stock, twisted between layers to opposite.2 water absorbent rate of water blocking yarn is high, and expansion is rapid when meeting water, filling Cable core gap, longitudinal water-blocking effect are good, and with good tensile strength and thermal stability, it is high from Effect of Hyperthermic Environment Multiplying power absorbent material is combined uniformly secured with base material, and there is no overburden stripping, lamination problem, technical performance is stablized, practicability By force.

Fire-retardant belting layer 6 is coated on the outside of the conductive unit, is filled between fire-retardant belting layer 6 and conductive unit Flame resistant filler layer 5, the outside of fire-retardant belting layer 6 are coated with woven shield 7, and the outside of woven shield 7 coats waterproof layer 8, The outside cladding restrictive coating 9 of waterproof layer 8.The fire-retardant belting layer 6 is fire-retardant band made of low-smoke non-halogen flame-retardant glass cloth tape Layer is without any halogen and mixed equipped with highly effective inorganic flame-proof agent, addition metal hydrate etc. in dip-coating on the glass fibers Solution is closed, is made through the advanced technologies flow such as impregnation heat cure.Amount of heat can be absorbed in combustion, prevent flame It passes through, protects insulating layer from burning, and form carbon shell, isolation air, hinder the supply of oxygen and the flowing of fuel gas, The smog discharged when resisting cable further to burn, while burning is few, substantially reduces fire and so does harm to degree.And be easy to around Bag does not absorb water and can prevent cable moisture in storage, operational process from invading insulating layer.

Preferably, the section of the conductor 1 is circular, sectional area 0.5-10mm2.

Preferably, if the conductor 1 can have dried layer, if every layer of conductor for having the equal section of carried interest, per share to have several Conductor monofilament, and in bundle strand structure, in the structure that tangles again between stock and stock, twisted between layers on the contrary, and in conductor monofilament Water blocking yarn 2 is filled in gap.

Preferably, the insulating layer 4 and restrictive coating 9 are made of thermoplastic low-smoke halide-free fireproof composite polyolefine material.Pass through Polyethylene linear molecular structure by being crosslinked specially treated, is changed into solid by low smoke and zero halogen special insulation material extrusion forming Network molecular structure substantially increases the electric property of product, physical property, mechanical performance and other properties, not only resistance to High temperature and having the characteristics that does not prolong combustion and will not generate hydrogen halide, such cable just do not discharged in burning pernicious gas and Smog will not cause " secondary disaster ".

Preferably, the flame retardant coating 3 uses synthetic mica carrying material through being overlapped wrapped be made repeatedly.

Preferably, the shielded layer 7 is woven using more bare copper wires or tinned wird.The shielded layer 7 of design can resist Electromagnetic induction, imperfect earth and cable Conduction Interference reduce inductance and avoid strong thunder and lightning galvanomagnetic-effect voltage to electrical equipment instrument The punch through damage of device, the features such as preventing induced potential excessive, but also as the passage of short circuit current flow, the guarantor that neutral core can be played Shield acts on.

Preferably, the waterproof layer 8 uses and blocks water carrying material through being overlapped wrapped form repeatedly.It is with tension, temperature tolerance Can banding substrate layer and the high magnification absorbent material layer that is uniformly attached on substrate layer, between two layers can by being bonded, coating, Impregnating various ways are combined.Advantage：Thickness is thin, and water absorbent rate is high, and expansion is rapid when meeting water, filling cable core gap, longitudinal direction Block-water effect is good, and with good tensile strength and thermal stability, from Effect of Hyperthermic Environment, high magnification absorbent material with Base material combination is uniformly secured, and there is no overburden stripping, lamination problems, and technical performance is stablized, highly practical.

The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the technical solution that the scope of protection of the utility model should be recorded with claim, the technical solution recorded including claim The equivalents of middle technical characteristic are protection domain.Equivalent substitution i.e. within this range is improved, also in the utility model Protection domain within.
