Description
Technical field
The utility model relates to a kind of cable, especially relates in a kind of novel self-supporting tensile type and presses power cable with cross-linked polyethylene insulation.
Background technology
As everyone knows, along with China's economy and the development of electric power and the quick growth of urban skyscraper, due to crosslinked cable excellent electrical properties, working temperature is high, transmission capacity is large, and the use of China's wire armoring crosslinked cable is very universal, and the thing followed is that user is more and more higher with the safety requirements laid to the quality of cable, manufacturer also improves requirement to the control of production cost, proposes challenge to traditional cable wire sheathed structure.
Originally the cable bearing pulling force adopts wire armoring to be generally laid in skyscraper and the larger environment of drop, the own wt of cable substantially all acts on steel wire, steel wire is wrapped on cable by many, the power being easy to when laying cause every root steel wire to be subject to is inconsistent, cable landing is easily caused to cause the accident, in addition because steel wire is that the steel wire after stressed be wrapped on cable can fall into into cable surface, cause cable fault, simultaneously because traditional structure causes cable size very large, increase market cost.So the crosslinked cable of development of new wire armoring structure seems very important.
The defect of background technology and deficiency have 5 points.1, steel wire is wrapped on cable by many, and the dynamics being easy to when laying cause every root steel wire to be subject to is consistent, easily causes cable landing to cause the accident; 2, because steel wire is wrapped on cable, steel wire can fall into into cable surface after stressed, causes cable fault; 3, because traditional structure causes cable size very large, improve the use amount of external protective material, increase cable cost.
Summary of the invention
The utility model, mainly for the above-mentioned technical problem existing for prior art, provides a kind of fan-shaped high-strength combination lifting core to bear in cable deadweight and pulling force, steel wire uniform force, safe and reliable novel self-supporting tensile type and presses power cable with cross-linked polyethylene insulation.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: press power cable with cross-linked polyethylene insulation in a kind of novel self-supporting tensile type, comprise many conductors and conductor screen, conductor screen is arranged with insulating barrier and insulation screen outward successively, it is characterized in that being respectively arranged with several between many described conductors is fan-shaped equally distributed high-strength combination lifting core, center between many described conductors is provided with center-filled rope, copper strip shielding layer is arranged with outside described insulation screen, high-strength combination bundling belt is surrounded with outside described copper strip shielding layer, oversheath is arranged with outside described high-strength combination bundling belt.The utility model changes the wrapped structure of traditional steel wire armouring cables wire, total steel wire three steel strand wire are substituted, be made in fan packing and form " fan-shaped high-strength combination lifting core ", be filled into the gap after cable cabling, make steel wire to the pressure uniform of cable, install firmly, reduce the infringement to cable.To solve when former steel wire armored cable is produced by many steel wire windings on cable, the power being easy to when laying cause every root steel wire to be subject to is inconsistent, easily causes cable landing to cause the accident and to fall into into cable surface with stressed rear steel wire, cause cable fault problem.And decrease the outside diameter of cable and reduce production cost.This invention adds cable flexibility and is conducive to cable laying installation, improves the operational reliability of cable.
As preferably, described insulating barrier is crosslinked polyetylene insulated layer.
Therefore, the utility model has and bears cable deadweight and pulling force, steel wire uniform force, the feature such as safe and reliable with fan-shaped high-strength combination lifting core.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
As shown in Figure of description 1, power cable with cross-linked polyethylene insulation is pressed in a kind of novel self-supporting tensile type, comprise many conductors 1 and conductor screen 2, conductor screen 2 is outer is arranged with insulating barrier 3 and insulation screen 4 successively, being respectively arranged with several between many conductors 1 is fan-shaped equally distributed high-strength combination lifting core 5, center between many conductors 1 is provided with center-filled rope 6, copper strip shielding layer 7 is arranged with outside insulation screen 4, be surrounded with high-strength combination bundling belt 8 outside copper strip shielding layer 7, outside high-strength combination bundling belt 8, be arranged with oversheath 9.Insulating barrier 3 is crosslinked polyetylene insulated layer.
The utility model is the armouring technology that steel wire and packing material combined together: substituted by armouring wire many steel strand wire, and steel strand wire and packing material are combined together, steel wire does not directly contact with cable, steel wire uniform force, compare the pulling force and pressure that reduce cable with traditional structure when steel wire is stressed, reduce the damage to cable, bear cable deadweight and pulling force with fan-shaped high-strength combination lifting core.Increase by cable softness after this structure and be conducive to cable laying installation.Improve the security reliability of cable line.
Combine together steel wire and packing material armouring technology: substituted by armouring wire many steel strand wire, and steel strand wire and packing material are combined together, steel wire does not directly contact with cable, steel wire uniform force, compare the pulling force and pressure that reduce cable with traditional structure when steel wire is stressed, reduce the damage to cable, bear cable deadweight and pulling force with fan-shaped high-strength combination lifting core.Increase by cable softness after this structure and be conducive to cable laying installation.
Should be understood that this embodiment is only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
