Description

A kind of mining integrated cable

Technical field

The utility model relates to cable, is specially a kind of mining integrated cable, is applied to electric power transmission and communication transfer under various mines.

Background technology

Now from low pressure to high-voltage transmission, have greatly the trend that replaces aerial exposed electric wire from underground jacketed cable, high-voltage transmission cable application is more and more wider.In the use procedure of high-voltage transmission jacketed cable, often in sheath between phase line, between cable and external environment occur that local electrophoresis blows out phenomenon (partial discharge ablation cable cover(ing)), in order to overcome this phenomenon, be usually filling conductive plastic establish a parallel ground connection zero line and contact with conductive plastic between cable jacket and inner sheath, to shield electrophoresis, blow out.Equipment electrifing degree under Modern Pit is very high, under general longer mine, needs high-tension cable, communication cable, and electric power transmission and electric communication transfer separate.Because subsurface environment is severe, both required fire-retardantly, also requirement can not produce a bit electric spark, to the shielding of cable, requires higher.The problem that common design exists is: ground connection zero line is not distributed between interior oversheath equably, at the opposite side away from conduction zero line, still has electric capacity to blow out phenomenon; Forceful electric power transmission and communication transfer separate, and are not integrated in one, connect up more random.

Utility model content

The purpose of this utility model is: overcome the defect that existing high-tension cable transfer function is single, shielding is not strong, a kind of improved mining integrated cable is provided, make can transferring high voltage electric power again can transmit communications signals, anti-puncture, antistatic, phenomenon occurs to prevent that electrophoresis from blowing out etc.

The technical solution of the utility model is: a kind of mining integrated cable, comprise cable core and external insulation fire retardant jacket, in external insulation fire retardant jacket, there is three-phase electricity cable core, every phase cable core has insulating sleeve I in one deck outward, outer one deck conductive plastic I that is with of interior insulating sleeve I, this conductive plastic layer I has one deck to be wound around conductive wire outward; In band, between the three-phase electricity cable core of insulating sleeve I, also have a Cable Core with sheath and at least one tension steel wire, the periphery jointly adding after turning round also has insulating sleeve II, conductive plastic layer II, conductive wire, external insulation fire retardant jacket in one deck successively.

In described band, adding between the three-phase electricity cable core of insulating sleeve turned round plastic cement filler between gap.

Between three-phase electricity cable core and interior insulating sleeve, also have one deck easily to peel off winding plastic band, be easier to cable core and sheath to peel off when facilitating cable joint.

The design is by improving the distribution of conductive wire in sheath, during use, conductive wire in sheath is drawn out to earth connection and connects, can more effectively shield between three-phase electricity and cable external environment between spark, and then the electrophoresis that effectively solves high-tension cable is blown out problem., Cable Core can be extracted out as communication use meanwhile, make the design's product can transferring high voltage electric power again can transmit communications signals, anti-puncture, antistatic, phenomenon occurs to prevent that electrophoresis from blowing out etc., especially suitable modernization intelligence mine is used.
