Each set of power wire cores comprises a first conductor respectively, and the outer side of the first conductor is orderly provided with a first insulating layer and a semi conductive shielding layer. The set of ground wire core comprises a second conductor which is coated by a second insulation layer. The control wire core comprises three insulating conductors which are mutually stranded, and the outer side of the stranded insulating conductors is provided with a cladding layer. Each of the insulating conductors comprises a tensile carbon fiber respectively, the outer side of the tensile carbon fiber is stranded with a tinned copper wire conductor, and the outer side of the tinned copper wire conductor is wrapped by a third insulating layer. The high strength special flexible coal mining machine cable has the advantages of reasonable structure and bending and dragging resistance, and the performance requirements of a modern coal mining machine cable for a mine can be satisfied.

Description

The special soft electric cable for coal mining machine of a kind of high strength

Technical field

The utility model relates to the cable technology field, particularly the structure of the special soft electric cable for coal mining machine of a kind of high strength.

Background technology

Electric cable for coal mining machine is used for the power supply of coal-winning machine or similar devices, need follow coal-winning machine during work all around moves around, cable all is subjected to serious dilatory, extruding, crooked and reverse and the impact of coal cinder, and conductor ruptures easily, so its mechanical performance is had relatively high expectations.Traditional electric cable for coal mining machine control core more carefully is easy to fracture, and fracture back coal-winning machine will quit work; If power core fracture untimely discovery again, coal-winning machine might be burnt out.

Summary of the invention

The utility model purpose is to overcome the deficiency that common electric cable for coal mining machine exists, and the special soft electric cable for coal mining machine of high strength of performances such as a kind of high strength, anti-bending, oil resistant, fire-retardant, anti-daylight, anti-ozone, acid and alkali-resistance, chemical-resistant reagent is provided.

The utility model comprises three groups of stranded power cores mutually, one group of ground wire core and one group of control core, at described three groups of stranded power cores, the outside of one group of ground wire core and one group of control core sets gradually inner restrictive coating, fibrage reinforced layer and external sheath layer; Described every group of power core comprises first conductor respectively, sets gradually first insulating barrier and semiconductive shielding layer in described first conductor outside; Described ground wire core comprises second conductor, at described second conductor outside parcel second insulating barrier; Described control core comprises three mutual stranded insulated electric conductors, at described stranded insulated electric conductor arranged outside coating layer; Described insulated electric conductor comprises the tension carbon fiber respectively, twists the tinned copper wire conductor again in the outside of described tension carbon fiber, at described tinned copper wire conductor outside parcel the 3rd insulating barrier.

The utility model is rational in infrastructure, and anti-bending is dilatory, and serviceability is good, and product has performances such as high strength, oil resistant, fire-retardant, anti-daylight, anti-ozone, acid and alkali-resistance, chemical-resistant reagent simultaneously.Can satisfy mine with the performance requirement of modernized electric cable for coal mining machine.
