Abstract

The utility model discloses a flame retardation anti-interference mining cable constituted by a ceramic fireproof protection layer, a metal protection layer, a silvering copper wire braided shielding layer, control illumination wire cores, ground wire cores, fluororubber insulation layer, and phase line cores. The inner side of the metal protection layer is provided with the silvering copper wire braided shielding layer in a wrapped-extruded manner, and the outer side is wrapped by the ceramic fireproof protection layer. The outer sides of the control illumination wire cores are provided with polyvinyl chloride sheaths. The outer side of the fluororubber insulation layer is symmetrically and concentrically provided with two control illumination wire cores and six ground wire cores. The silvering copper wire braided shielding layer is used to wrap the control illumination wire cores, the ground wire cores, and the phase line cores together in an extruded manner. The flame retardation anti-interference mining cable has advantages of fireproof effect, anti-interference effect, various functions, and ability of solve problems of common cables in coal mine such as weak signals and single function.

Description

A kind of fire-retardant anti-interference mining cable

Technical field

The utility model relates to field of cables, relates 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.

Utility model content

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

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

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

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, the utility model beneficial effect is embodied in:

1, the ceramic fire resistant protective layer 1 in the utility model, 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 utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
