The flame-retardant monitoring and shielding mining rubber-sleeved flexible cable has high flame-retardant performance, is used securely and reliably, has functions of monitoring and shielding, and can meet a requirement for capacity expansion on mining equipment.
Description
Technical field
The utility model relates to the cable that a kind of colliery is used, and is specifically related to a kind of supervision shield type mining cable.
Background technology
Mining cable is meant that ground installation and the underground equipment used in the coal mining industry use the electric wire cable product; Use cable comprising the communication on coal-winning machine, the transporter, illumination and signalling arrangement, and the feed cable used of electric drill cable, cap lamp electric wire and mobile substation, down-hole etc.Cable resists the external force ability in the electric equipment of down-hole the weakest, is damaged the most easily, causes stopping production, the person, equipment or bigger accident to take place.Downhole cable causes overload to break because of mechanical load changes greatly easily, near the cable that particularly exploiting field reaches, uses, and along with the operation well depth is high-frequency round mobile and crooked, the cable cover(ing) serious wear also causes that easily core breaks., methane accumulation place abominable owing to circumstance complication, the condition of work of use sets off an explosion easily, and is therefore not only very high to the security requirement of cable own, and very high with the shielding properties requirement of cable to the shielding occasion.If the conductive surface of cable is rough, rounding not, cause point discharge easily, cause the electric field structure imperfection.Simultaneously, the cable shield performance is bad, also has the contaminated problem of insulation.In a lot of occasions, also need signal be provided for the surveillance of equipment, when having foreign matter to get into cable inside in the external world, need pass the signal to the power safety protective device.Along with the development of coal industry, the dilatation of down-hole coal excavation apparatus makes the electric pressure of transformer rise to 6/10kV, 8.7/10kV, causes existing down-hole to be moved with transformer and similar devices and can't satisfy use with cable.
Summary of the invention
Goal of the invention: the purpose of the utility model is in order to overcome deficiency of the prior art; A kind of good flame resistance is provided; Safe and reliable, can satisfy supervision and can satisfy shielding again, but also can satisfy the fire-retardant supervision shield type rubber sheathed flexible cable for mine that the winning equipment dilatation is used.
Technical scheme: in order to solve the problems of the technologies described above; The described fire-retardant supervision shield type rubber sheathed flexible cable for mine of the utility model, it comprises three power line core conductors, outside said power line core conductor, is provided with conductor shield; Outside said conductor shield, be provided with insulating barrier; Outside said insulating barrier, be provided with insulation screen, outside said insulation screen, be provided with inner sheath, outside said inner sheath, be provided with pilot wire core and semi-conductive tape covering; Outside said supervision core and semi-conductive tape covering, be provided with the insulating bag band, oversheath arranged at said insulation band peripheral hardware.
Outer conductor shield, insulating barrier and the insulation screen of said power line core conductor adopts three-layer co-extruded continuous vulcanization moulding.
Said insulation screen is also as earth connection.
Said fire-retardant supervision shield type rubber sheathed flexible cable for mine is 8.7/10kV and following cable.
The utility model adopts new elastomeric material macromolecule compound prescription technology and modification blend new process for processing process technology; Improve and improved insulation property, physical property and the electrical property of cable; Adapt to the needs that voltage levels more moves Plastic-sheathed Cable, provide dielectric property excellent reliable and stable 8.7/10kV and following fire-retardant supervision shield type rubber sheathed flexible cable for mine.
The insulated wire cores of the utility model adopts three-layer co-extruded continuous vulcanization production Technology; Reliable and stable quality is provided, high performance rubber internal shield, high insulation ethylene-propylene rubber insulating barrier, has been prone to peel off the rubber insulation outer shielding layer, its insulation rubber tensile strength is not less than 7.0MPa; Be superior to the national standard requirement; Be higher than domestic like product, sheath rubber tensile strength is not less than 14.0MPa, also is higher than domestic like product; Make the finished product 3.5Uo of anti-the power frequency not puncture in withstand voltage 5 minutes simultaneously; Standard greater than German 3Uo; With auxiliary cores such as multi-core controlled cables, screen has good anti-interference simultaneously, and transition resistance also is superior to the national standard requirement; When rubber sheath modification blend, add assistant, make sheath have certain properties such as anticorrosion.
Beneficial effect: the utility model compared with prior art; Its remarkable advantage is: the three-decker of the outer co-extrusion continuous vulcanization moulding of power line core conductor; Steady quality is reliable; Be provided at an outer portion with and keep watch on core and restrictive coating, tensile strength is high, and the cable of the production of adopting new technology can satisfy the requirement of winning equipment dilatation.
