Abstract
The invention discloses a low-smoke halogen-free cable for a shield, and relates to the technical field of a cable. The low-smoke halogen-free cable comprises a first sheath, insulation power cores, a ground core and a control core, wherein the each insulation power core is formed by successively arranging a metal shielding layer, an ethylene propylene terpolymer rubber insulation layer and a type-six tin-coated copper conductor on an aramid fiber core from the outside to the inside; the ground core is formed by extruding a type-six tin-coated copper conductor by a conductor semiconducting shielding layer; the control core is formed by extruding control core groups by a second sheath; each control core group is formed by successively extruding an aramid fiber core by a conductor semiconducting shielding layer and a type-six tin-coated copper conductor; the three insulation power cores and the one control core are extruded by a water-blocking wrapping tape to form a cable core; the ground wire is arranged in the middle of the cable core, and a water-blocking yarn is arranged in a gap of the cable core; and the water-blocking wrapping tape is externally provided with the second sheath. The cable provided by the invention is softer and has higher tension resistance, has a water-blocking function, is good in tension-resistant and wear-resistant performance, and can satisfy the requirement of the shield for the cable under a complex working condition.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of low smoke and zero halogen cable for shield machine.
Background technology
Along with the progress of science and technology, the extensive utilization of a kind of novel subterranean tunnel excavating equipment shield machine, drive the widespread demand of cable for shield machine.The use bad environments of cable for shield machine, cable not only often to bend movement, also it is typically placed in the immersion of grit muddy water, in use cable not only to bear the powerful mechanical shearing bending pulling force of the generation of shield machine digging moving process, the hard thing extruding such as grit rock and the muddy water that are additionally subjected to surrounding soak, and therefore cable very easily damages.Applying to cable for shield machine on domestic market, the cable for shield machine of the long life of the tensile wear-resistant that is provided simultaneously with blocking water is few, it is impossible to meet the market great demand to cable for shield machine.
Summary of the invention
Present invention seek to address that technological deficiency of the prior art, it is provided that a kind of low smoke and zero halogen cable for shield machine.
The solution of the present invention is as follows: a kind of low smoke and zero halogen cable for shield machine, including sheath, insulated power core, wire core and control conductor；Described insulated power core is successively set on aramid fiber core is from outside to inside formed by metal screen layer, EPDM rubber insulating barrier, six class tinned copper conductor；Described wire core is to be extruded six class tinned copper conductors by conductor semiconductive shielding layer to form；Described control conductor is to be extruded control conductor group by sheath to form；Control conductor group is to be extruded aramid fiber core successively formed by conductor semiconductive shielding layer, six class tinned copper conductors；Three thoroughly do away with the edge power wire core band that blocked water with a control conductor extrudes into cable core；It is provided with a wire core in the middle of cable core, the gap of cable core is provided with water blocking yarn；The described band that blocks water is outside equipped with sheath.
It is provided with insulated non-metal screen layer between described metal screen layer and EPDM rubber insulating barrier；It is provided with conductor semiconductive shielding layer between six class tinned copper conductors and EPDM rubber insulating barrier.
Gap between described sheath and control conductor group is provided with the band that blocks water.
Described six class tinned copper conductors and aramid fiber core adopt stranded in the same direction forming.
The present invention is reasonable in design, simple and practical, insulated power core and control conductor conductor adopt six classes tin plating soft copper conductor to form with aramid fiber core is stranded, conductor is more soft and conductor bears stretching resistance and significantly improves, water blocking yarn and the outer wrapped band that blocks water of cable core are filled in cable core core gap, make cable possess water stop function；And the tensile wear-resistant performance of cable is strong, it is possible to meet the requirement to cable security performance and life-span under the working condition that shield machine is complicated.
