Abstract

The invention discloses a wear-resistance, low-smoke and environment-friendly computer cable. The wear-resistance, low-smoke and environment-friendly computer cable comprises a metal hose, cable wire cores and six layers of sheaths, wherein the six layers of sheaths wrap the cable wire cores, each cable wire core comprises a copper conductor, a mica layer and an insulation layer, the three groups of cable wire cores are twisted around the metal hose to form a triangle, and the six layers of sheaths wrapping the cable wire cores are sequentially a wrapping tape layer, a water blocking layer, a shielding layer, an inner sheath, a armor layer and an outer sheath from inside to outside. The cable has the advantages of high interference resistant capability, high shielding performance, low smoke, environmental friendliness and long service lifetime, has high practical value, and is worth to be promoted, and the information transmission stability can be improved.

Description

A kind of wear-resisting low cigarette environmental protection computer cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of wear-resisting low cigarette environmental protection computer cable.

Background technology

Computer cable is widely used in the every field such as electric power, information, being mainly used in the transmission of frame, existing cable shielding is poor, and poor anti jamming capability, information fidelity are poor, therefore jitter, not fogging clear, and cable accommodative ability of environment is poor, the life-span is relatively low.

Summary of the invention

It is an object of the invention to provide that a kind of capacity of resisting disturbance is strong, shield, low cigarette environmental protection, life-span length, transmit frame wear-resisting low cigarette environmental protection computer cable clearly.

To achieve these goals, the wear-resisting low cigarette environmental protection computer cable of one of the present invention, it includes six layers of sheath of metal hose, cable core and parcel cable core；Described cable core includes copper conductor, mica layer and insulating barrier；Described mica layer parcel copper conductor；Described mica layer outer cladding insulating barrier；Described cable core has three groups；Three groups of cable cores are around the stranded formation triangular shape of described metal hose；Described three groups of cable cores are uniformly extruded in inside described six layers of sheath；Six layers of sheath of described parcel cable core from interior successively: belting layer, water blocking layer, screen layer, inner sheath, armor and oversheath.Gap portion between described belting layer and insulating barrier also sets up packed layer；Four groups of silver-plated tension aluminium wires are uniformly installed between described screen layer and armor；Described silver-plated tension aluminium wire, through screen layer and armor, runs through inner sheath.

Described oversheath is low-smoke non-halogen flame-retardant polyethylene layer.

Described insulating barrier adds inhibitor of being fuming.

Described silver-plated tension aluminium wire cross-sectional diameter is 0.65mm.

The invention has the beneficial effects as follows in sum: capacity of resisting disturbance is strong, shield, low cigarette environmental protection, life-span length, transmission frame are clear, and the silver-plated tension aluminium wire that cable is arranged can distort repeatedly in varying environment, and use improves the adaptability of cable.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention.

Detailed description of the invention

As it is shown in figure 1, a kind of wear-resisting low cigarette environmental protection computer cable, it includes six layers of sheath of metal hose 12, cable core and parcel cable core；Cable core includes copper conductor 1, mica layer 2 and insulating barrier 3；Described mica layer 2 wraps up copper conductor 1；Described mica layer 2 outer cladding insulating barrier 3；Cable core has three groups；Three groups of cable cores are around the stranded formation triangular shape of metal hose 12；Three groups of cable cores are uniformly extruded in inside six layers of sheath；Parcel cable core six layers of sheath from interior successively: belting layer 5, water blocking layer 6, screen layer 7, inner sheath 8, armor 9 and oversheath 10.Armor 9 strengthens the intensity of cable, optimizes the wear resistance properties of cable.

Gap portion between belting layer 5 and insulating barrier 3 also sets up packed layer 4；Packed layer 4 is soft foam insert, and soft foam insert water-swellable secondary strengthens the water proofing property of core.

Four groups of silver-plated tension aluminium wires 11 are uniformly installed between screen layer 7 and armor 9；Silver-plated tension aluminium wire 11, through screen layer 7 and armor 9, runs through inner sheath 8.The installation of silver-plated tension aluminium wire 11 improves cable strength makes cable repeatedly can distort in varying environment, uses the adaptability that improve cable.

Oversheath 10 is low-smoke non-halogen flame-retardant polyethylene layer.

Insulating barrier 3 adds inhibitor of being fuming.

Silver-plated tension aluminium wire 11 cross-sectional diameter is 0.65mm.

The above is the embodiment of the present invention, therefore all equivalences done according to the structure described in the present patent application scope, feature and principle change or modify, and are all included within the scope of present patent application.
