Abstract
The invention relates to a fire-resisting low-smoke non-halogen cable, which comprises three conductors with insulation layers. Each conductor is externally wrapped with a coloring layer; low-smoke non-halogen flame-resisting polyolefin plastics is colored to form the coloring layer; the three conductors are sequentially and externally coated with a coating belt and a sheath; a filling rope is arranged among the three conductors and the coating belt; the insulation layer comprises a mica belt and a ceramic composite silicone rubber belt; the filling rope is a glass fiber rope; the insulation is a ceramic composite silicone rubber composite belt; and the sheath is a low-smoke non-halogen flame-resisting polyolefin plastic sheath. The fire-resisting low-smoke non-halogen cable has the advantages that the processing technology is simple, the manufactured length is large, the cost is low, the fire-resisting performances are good, the cable is safe and non-toxic, the environment is not polluted, and the weight is light.
Description
Technical field
The present invention relates to a kind of cable, specifically fire-resistant low-smoke halogen-free cable.
Background technology
Mineral insulated cable has that factory length is short, joint is processed complicated defect, bad if joint is processed, and can make the insulation resistance of cable sharply decline, and weight is large, and these drawbacks have also limited the development of mineral insulated cable.
Summary of the invention
The present invention is intended to overcome the defect of prior art, and a kind of fire-resistant low-smoke halogen-free cable is provided, proxy mineral insulated cable, and cost is low, and fire resistance is good.
In order to solve the problems of the technologies described above, the present invention is achieved in that
A kind of fire-resistant low-smoke halogen-free cable, it comprises three conductors with insulation, and each conductor outsourcing has dyed layer, it is characterized in that: described dyed layer is low smoke halogen-free flame-retardant polyolefin coloring plastic, three conductors are surrounded by band and sheath outward successively, between three conductors and band, are provided with gasket for packing.
Described fire-resistant low-smoke halogen-free cable, is characterized in that: described insulation is mica tape and pottery silicon rubber composite band.
Described fire-resistant low-smoke halogen-free cable, is characterized in that: described gasket for packing is glass fiber rope.
Described fire-resistant low-smoke halogen-free cable, is characterized in that: described band is pottery silicon rubber composite band.
Described fire-resistant low-smoke halogen-free cable, is characterized in that: described sheath is low smoke halogen-free flame-retardant polyolefin plastic sheath.
The invention has the beneficial effects as follows: processing technology is simple, factory length is large, and cost is low, and fire resistance is good, and safety non-toxic is free from environmental pollution, lightweight.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1: a kind of fire-resistant low-smoke halogen-free cable, it comprises three conductors 1 with insulation, each conductor outsourcing has dyed layer 3, described dyed layer is low smoke halogen-free flame-retardant polyolefin coloring plastic, three conductors are surrounded by successively outward between band 4 and 5, three conductors of sheath and band and are provided with gasket for packing 6; Described insulation is mica tape 7 and pottery silicon rubber composite band 8; Described gasket for packing is glass fiber rope; Described band is pottery silicon rubber composite band; Described sheath is low smoke halogen-free flame-retardant polyolefin plastic sheath.Insulation of the present invention adopts mica tape and pottery silicon rubber composite band to carry out wrapped; this insulation is under flame calcination; can discharge internal water molecule; itself become ceramic-like material by soft condition; form one deck containment vessel, being bonded on conductor tightly, pottery material has insulating barrier function; make the conductor can short circuit, thereby reach fire-resistant effect.
