Abstract
The utility model discloses a kind of fireproof cable, the technical problem that solve is to provide a kind of can production and bending property good fireproof cable length heavy in section greatly.For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of fireproof cable, comprise conductor, described conductor is coated with ceramic plastic layer or rubber insulation, glass fiber material resilient coating and corrugated stainless steel tubing or copper corrugated pipe outward successively, described ceramic plastic layer or be provided with glass fibre packed layer between rubber insulation and glass fiber material resilient coating.The utility model oversheath adopts corrugated stainless steel tubing or copper corrugated pipe and low smoke, zero halogen polyolefin flame-retardant layer composite construction, and whole cable is airtight, normally can use at burning bad border Water spray on cable.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of fireproof cable.
Background technology
Traditional fireproof cable generally has three kinds of forms: (1) wrapped mica tape is as insulating barrier on cable conductor, and cable can come off by vibrations mica tape, and can not play insulating effect, this cable normally can not use in special burning bad border; (2) magnesium oxide cable, this cable adopts copper pipe to put into copper pipe filling magnesia powder again, magnesium oxide cable is manufactured again through operations such as drawings, this cable is due to inner tight and hermetically sealedly (cable is shaken and Water spray burns bad border) normally can use in special burning bad border, but its manufacturing process is complicated, delivery length is shorter, generally be no more than 100m, large length cables can only use transition joint, bending property is bad, and manufacturing equipment price is high, cable is expensive; (3) using ceramic rubber as insulation, other is identical with common cable, due to more crisp after ceramic rubber in combustion porcelain, it is easily cracked when cable shakes, the insulation of cable likely destroys, under Water spray state, porcelain glue absorbs moisture, causes insulation property to reduce, therefore can not use in special flame combustion bad border.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of can production and bending property good fireproof cable length heavy in section greatly.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of fireproof cable, comprise conductor, described conductor is coated with ceramic plastic layer or rubber insulation, glass fiber material resilient coating and corrugated stainless steel tubing or copper corrugated pipe outward successively, described ceramic plastic layer or be provided with glass fibre packed layer between rubber insulation and glass fiber material resilient coating.
Corrugated stainless steel tubing described in the utility model or copper corrugated pipe are also provided with polymer protection layer outward.
Polymer protection layer described in the utility model is low smoke, zero halogen polyolefin flame-retardant layer.
The utility model compared with prior art, cable adopts ceramic plastics or rubber as insulating barrier, cable is porcelain in flame combustion environment, define the insulation isolation of cable in hot environment, simultaneously using fiberglass braided material as the wrapping of cable and resilient coating, clearance for insulation also adopts glass fibre to fill.Oversheath adopts corrugated stainless steel tubing or copper corrugated pipe and low smoke, zero halogen polyolefin flame-retardant layer composite construction, and whole cable is airtight, normally can use at burning bad border Water spray on cable.
Accompanying drawing explanation
Fig. 1 is existing conventional conductor wrapped mica tape fire-resisting cable structural representation.
Fig. 2 is existing ceramic rubber-covered fireproof cable structural representation.
Fig. 3 is existing magnesium oxide construction of cable schematic diagram.
Fig. 4 is the utility model fireproof cable structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: the wrapped mica tape fire-resisting cable of conventional conductor as shown in Figure 1 comprises conductor 1, wrapped mica tape 2, insulating barrier 3 (insulating material is XLPE or PVC), packed layer 4, lapping layer 5, oversheath 6 (sheath material is PVC or polyolefin).Be illustrated in figure 2 magnetization glue insulated cable, comprise ceramic rubber insulation 7 and extrude sheath 8 (sheath material is generally silicon rubber).Be illustrated in figure 3 magnesium oxide cable, comprise the magnesium oxide after sintering 9 and copper pipe 10.
As shown in Figure 4, fireproof cable of the present utility model comprises conductor 1, conductor 1 is outer is coated with ceramic plastic layer or rubber insulation 11, glass fiber material resilient coating 13 and corrugated stainless steel tubing or copper corrugated pipe 14 successively, wherein, ceramic plastic layer or be provided with glass fibre packed layer 12 between rubber insulation 11 and glass fiber material resilient coating 13.In addition, can also be provided with polymer protection layer 15 (also can not having, directly using metal bellows as oversheath) outside corrugated stainless steel tubing or copper corrugated pipe 14, this polymer protection layer 15 is low smoke, zero halogen polyolefin flame-retardant layer.
The utility model adopts ceramic plastics or rubber insulation material as the insulating barrier of cable; using glass fiber material as resilient coating; oversheath adopts corrugated stainless steel tubing or copper corrugated pipe; also polymer protection layer can be covered in addition; for full-closed structure; extraneous Water spray can not have influence on the insulation of cable, and this cable normally can use (this burning situation comprises cable and shaken and have Water spray on cable) within a certain period of time in special flame combustion environment.Because the utility model material therefor is all ep-type material, outermost layer adopts low smoke, zero halogen polyolefine material, and therefore fireproof cable of the present utility model also has the characteristics such as Halogen, low cigarette, nontoxic, environmental protection.
Claims (3)
1. a fireproof cable, comprise conductor (1), it is characterized in that: described conductor (1) is coated with ceramic plastic layer or rubber insulation (11), glass fiber material resilient coating (13) and corrugated stainless steel tubing or copper corrugated pipe (14) outward successively, described ceramic plastic layer or be provided with glass fibre packed layer (12) between rubber insulation (11) and glass fiber material resilient coating (13).
