Abstract
The utility model discloses a mining-signal-combination flexible cable. The cable comprises a cable core. The cable core comprises two main wire cores, one single shielded wire core, one shielded pair and one line pair. The each main wire core comprises a conductor and an insulating layer. The single shielded wire core comprises the conductor, the insulating layer, a shielding layer and a sheath layer. The shielded pair comprises two conductors which are wrapped by the insulating layer. The two conductors are twisted with each other and an outer side is successively wrapped with the shielding layer and the sheath layer. The line pair comprises the two conductors which are wrapped by the insulating layer. And the two conductors are twisted with each other and the outer side is successively wrapped with a tape wrapping layer and the sheath layer. The two main wire cores, the one single shielded wire core, the one shielded pair and the one line pair surround a filling rope and carry out stranded cabling. The outer side of the cable core is successively wrapped with a non-woven fabric taped covering, an inner sheath layer, an armor layer and an oversheath layer from inside to outside. The cable of the utility model can simultaneously output electric energy and a control signal in a well.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of mining signal combination flexible cable.
Background technology
Underground work, condition is restricted, and is also relatively high to the requirement of cable.Cable type both comprised the output electric energy, comprised again control signal, and the radical of cable increases thus, down-hole limited space, inconvenient underground work.
The utility model content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of mining signal combination flexible cable to be provided.
The utility model is achieved through the following technical solutions:
A kind of mining signal combination flexible cable includes cable core, it is characterized in that: described cable core includes two master cores, single screen and covers core, shielded pair, single line pair, and described master core includes conductor, insulating barrier; Described single screen is covered core and is included conductor, insulating barrier, screen, restrictive coating; Described shielded pair includes two conductors that are enclosed with insulating barrier, and after two conductor pair twists, the outside is enclosed with screen, restrictive coating successively; Described line is to including two conductors that are enclosed with insulating barrier, and after two conductor pair twists, the outside is enclosed with belting layer, restrictive coating successively; Two master cores, single screen are covered core, shielded pair, single line to carrying out twisted synthesizing cable around gasket for packing, and the outside of cable core is enclosed with nonwoven fabrics lapping layer, inner restrictive coating, armour, external sheath layer from inside to outside successively.
Described mining signal combination flexible cable is characterized in that: described armour adopts double-layer wire braiding armouring, and density reaches more than 80%.
Described mining signal combination flexible cable is characterized in that: the soft copper conductor that described each conductor is strands.
Described mining signal combination flexible cable, it is characterized in that: described insulating barrier, inner restrictive coating, external sheath layer all adopt thermoplasticity soft type plastic material.
The subject matter that the utility model solves:
1, can export simultaneously electric energy and control signal in the down-hole;
2, the utility model sheathed structure adopts double-layer wire braiding armouring, and cable can bear the deadweight of the high low head cable in down-hole;
3, the conductor of cable, armour, insulation, sheath all adopt soft structure, and conductor is that soft copper conductor, the armouring of strands adopts braiding sheathed structure, insulating sheath material all to adopt thermoplasticity soft type plastic material, is convenient to movement, the bending of cable;
4, owing to being that power core, control signal core are combined, reduce the radical of cable, facilitated underground work.
Can find out from the structure of cable, cable is divided into power core and shielding control signal core.The power core provides power supply for the down-hole, and cross-sectional area of conductor adopts 4mm
2Can satisfy the underground high-power lighting apparatus and carry power supply.The control signal core adopts the proof copper-wire braided shielding outward, and density reaches more than 80%, the interference of core and electromagnetic field, signal transmission accurately around having shielded.
The utility model has the advantages that:
The utility model conductor wire core adopts the good copper conductor of conduction, has the conductor resistance rate less, the advantage that ampacity is larger; Insulating barrier adopts electrical property polyethylene preferably, has good electrical property, corrosion resistant performance; Screen adopts proof copper-wire braided, makes the communication of cable and signal not be subjected to external interference, and cable is comparatively soft; Armour adopts the finer wire braiding, has strengthened like this mechanical performance of cable, has also protected cable and has not been subjected to external mechanical loss and bears the cable vertical tension.
