Abstract

The invention discloses an inflaming-retarding and anti-interference mine cable which is composed of a ceramic fireproof protection layer, a metal protection layer, a silver-plated copper wire braided shield layer, control illuminating wire cores, ground wire cores, a fluororubber insulated layer and a phase wire core. The silver-plated copper wire braided shield layer is arranged inside the metal protection layer in an extruded mode, and the metal protection layer is wrapped in the ceramic fireproof protection layer. A polyvinyl chloride sheath is arranged outside each control illuminating wire core. The two control illuminating wire cores and the six ground wire cores are symmetrically arranged outside the fluororubber insulated layer in a concentric mode. The control illuminating wire cores, the ground wire cores and the phase wire core are arranged together through the silver-plated copper wire braided shield layer in an extruded mode. The inflaming-retarding and anti-interference mine cable has various functions such as the fireproof function and the anti-interference function, and solves the problems that a common cable in a mine is weak in signal and single in function.

Description

A kind of fire-retardant anti-interference mining cable

Technical field

The present invention relates to field of cables, relate in particular to a kind of fire-retardant anti-interference mining cable.

Background technology

At present, existing borehole cable includes six core conductors that are equipped with insulating barrier, outside each core conductor, be provided with an outer jacket, and there is the problem that function ratio is more single in general six conductor cable, fire prevention, poor anti-interference, thereby make troubles to the use under mine, and affect product serviceability, in these fields, just should use so some to there is fire prevention, strong interference immunity, the cable of diverse in function, just can better ensure use, the fail safe of raising personnel, equipment.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of fire-retardant anti-interference mining cable.

The present invention takes following technical scheme to realize: a kind of fire-retardant anti-interference mining cable, it mainly by ceramic fire resistant protective layer, coat of metal, silver-gilt copper wire woven shield, control illumination core, wire core, fluorubber insulating barrier and phase wire core form, described coat of metal inside is extruded with silver-gilt copper wire woven shield, and coated outside has ceramic fire resistant protective layer; Described control illumination core outside is provided with pvc sheath; Described fluorubber insulating barrier is symmetrically arranged with one heart two outward and controls illumination core and six roots of sensation ground wire core; Described silver-gilt copper wire woven shield by control illumination core, together with wire core is extruded in phase wire core.

Described ground wire core adopts that tinned copper wire is stranded to be formed.

Described phase wire core adopts that tinned copper wire is stranded to be formed.

The present invention has following beneficial effect in sum: this cable has fire prevention, Anti-Jamming, and diverse in function solves common cable signal difference in mine, the problem of function singleness.

Accompanying drawing explanation

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

Wherein: 1, ceramic fire resistant protective layer; 2, coat of metal; 3, silver-gilt copper wire woven shield; 4, control illumination core; 5, pvc sheath; 6, wire core; 7, fluorubber insulating barrier; 8, phase wire core.

Embodiment

As shown in Figure 1, a kind of fire-retardant anti-interference mining cable, it mainly by ceramic fire resistant protective layer 1, coat of metal 2, silver-gilt copper wire woven shield 3, control illumination core 4, wire core 6, fluorubber insulating barrier 7 and phase wire core 8 form, described coat of metal 2 inside are extruded with silver-gilt copper wire woven shield 3, and coated outside has ceramic fire resistant protective layer 1; Described control illumination core 4 outsides are provided with pvc sheath 5; Outer two control illumination cores 4 and the six roots of sensation ground wire core 6 of being symmetrically arranged with one heart of described fluorubber insulating barrier 7; Described silver-gilt copper wire woven shield 3 by control illumination core 4, together with wire core 6 is extruded in phase wire core 8.

Described ground wire core 6 adopts that tinned copper wire is stranded to be formed.

Described phase wire core 8 adopts that tinned copper wire is stranded to be formed.

Compared with the prior art, beneficial effect of the present invention is embodied in:

1, the ceramic fire resistant protective layer 1 in the present invention, has fire prevention, oil resistant, wear-resisting, resistance to oxidation, and chemical-resistant stability energy, is adapted at the use under Mine Complicated operational environment;

2, coat of metal 2 can strengthen structural strength, prevents the damage of colliding with to internal core;

3, silver-gilt copper wire woven shield 3 makes cable have good anti-interference, guarantees signal strength signal intensity good under deep-well.

The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
