Description
Technical field
The present invention relates to a kind of power cable, particularly a kind of towing drum cable.Cable of the present invention is particularly useful for the mining towing drum cable of 26/35kV.
Background technology
The mining area mining machinery need pull drum cable at present, but the mining area operating mode is complicated, and environment is abominable, and the towing drum cable very easily in use is damaged; And cable in use need often drag, drags, twist, and requires the towing drum cable to have good pull resistance, completeness, barotolerance.
The patent of publication number CN 201117326Y (patent No.: ZL 200720042349.7) discloses a kind of " towing cable for down-hole digger ", and it adopts stranded flexible-cable core and inside and outside sheath structure.It exists shielding lower, the problem that cable center is easily broken.
The publication number CN 200972798Y (patent No.: patent ZL 200620026145.X); A kind of " buoy signal transmission power supply is supplied with composite tow " disclosed; This cable is filled gasket for packing at cable core, and the outsourcing isolation strip coats aramid fiber tension reinforced layer; Coat the isolation strip, extrude the polyurethane oversheath again.There is the general and flimsy problem of shield effectiveness equally in it.
Summary of the invention
The objective of the invention is deficiency, the towing drum cable of a kind of high shielding, softness, anti-towing is provided to prior art.
For realizing the foregoing invention purpose; The present invention adopts following technical scheme: a kind of towing drum cable; Constitute by three master cores, three ground cores, strengthening core, inner sheath, antitorque layer and oversheaths; Single master core is made up of conductor, conductor shield, insulating barrier, insulation screen and metal screen layer, and three master cores and three ground core circle spacings arrange, and conductor shield and insulation screen all are semiconductive shielding layers; Co-extrusion conductor screen, insulating barrier, insulation screen successively on the conductor excircle of said single master core, said insulation screen excircle is established metal screen layer; Said strengthening core is positioned in the middle of the master core of three circumferential arrangement; It between said inner sheath, the oversheath antitorque layer; Said inner sheath extrudes ground core and the master core that contains metal screen layer.
Further, said conductor all is cores that five types of conductor monofilament constitute with the ground core.
Further, said insulating barrier is the insulating barrier that ethylene-propylene rubber constitutes.
Further, said strengthening core is the core that high strength fibre silk or high duty metal silk constitute; Said antitorque layer is the antitorque layer that high strength fibre silk or high duty metal silk constitute.
Further, said metal screen layer is a tincopper fuse wire braided armor.
Further, said oversheath is the oversheath that adopts neoprene, haloflex, chlorosulfonated polyethylene, ethylene-propylene rubber, any material of polyurethane to constitute.
After adopting technique scheme, the present invention has following beneficial effect:
(1) the outer three-layer co-extruded conductor shield of the conductor of master core, insulating barrier, insulation screen, insulation screen peripheral hardware metal screen layer effectively improves the shielding of trailing cable; The preferred semiconductive shielding layer of conductor shield and insulation screen further improves shield effectiveness.
(2) master core was arranged with the ground core circle spacing, and strengthening core is positioned in the middle of the master core of three circumferential arrangement, established antitorque layer between inner sheath, the oversheath, and the trailing cable external diameter is diminished, and softness is easy fracture not, improves the flexible resistance of trailing cable.
(3) conductor adopts five types of conductor monofilament with the ground core, further makes the trailing cable deliquescing, and obtains more stable single wire fracture percentage elongation, and its conductor pitch control evenly.
(4) insulating barrier adopts ethylene-propylene rubber, further guarantees the insulating properties and the pliability of trailing cable.
(5) strengthening core adopts high strength fibre silk or high duty metal silk, and antitorque layer adopts high strength fibre silk or high duty metal silk, when playing layering, isolation, guarantees structure more consolidation, not easy fracture.
(6) adopt tincopper fuse wire braided armor, under the prerequisite that guarantees shielding, further make trailing cable soft, warping strength.
(7) oversheath is selected any material in neoprene, haloflex, chlorosulfonated polyethylene, ethylene-propylene rubber, the polyurethane for use, makes trailing cable adapt to different complex environments.
The present invention has high shielding, softness, anti-towing, safe, and advantage such as regular maintenance is convenient.
