Description

Environment-friendly type copper core second the third insulating elastomer sheath soft cable

Technical field

The utility model is related to a kind of environment-friendly type copper core second the third insulating elastomer sheath soft cables.

Background technology

Rubber-insulated electric wires and cables are to go out in the cable product that uses earliest and the widest product of purposes, the sixties Application of the EP rubbers in insulation is showed, the temperature resistant grade of electric wire is made to be increased to 90 DEG C by 60 DEG C.Present domestic standard In, to cabtyre cable, only remain EP rubbers and silicon rubber, dosage it is larger be EP rubbers.Rubber is produced at present During glue insulated cable, it is necessary to using dedicated rubber extruding machine equipment, and use steam continuous vulcanization, using vulcanization or peroxide as Crosslinking agent, while substantial amounts of additive need to be added in, technique is cumbersome, and very big waste can be caused when frequently replacing specification.And sulphur When changing using vapor crosslinking, hydrone is easily accessible insulating inner, influences insulating performance of cable and electric property, and most of steams Vapour is crosslinked the mode using coal burning aquatic products unboiled water steam, and a large amount of sulfur dioxide, nitrogen are generated during coal burning Oxide etc., these gases, which are dissolved in water, can form acid rain, and acid rain can cause to corrode to forest, statue, building etc., when coal not When fully burning, the pollutants such as carbon monoxide, carbon dioxide can be generated.Coal can generate solid granule, cause in burning To the dust pollution of air.Constantly develop as HVDC Transmission Technology receives significant attention in electric system, direct current The use of cable is more and more extensive, in the market mostly using crosslinked polyetylene insulated direct current cables, but since DC voltage cooperates with temperature Degree Gradient Effect increases the space charge amount for causing insulating surface, electric field strength increase, seriously affects the electrical property of insulation, drop The service life of low cable, in order to improve insulating performance of cable and electric property, improve the resistant of high or low temperature of cable, oil resistivity, The performances such as resistant to chemical etching simplify production process, reduce production cost and labour, realize Product Green environmental protection and protection people Class living environment, therefore a kind of environment-friendly type copper core second the third insulating elastomer sheath soft cable need to be researched and developed.

The content of the invention

The technical problem to be solved by the present invention is to provide one kind to have insulation performance and electric property height, service life Long, oil resistant, high temperature resistant, low temperature resistant, Halogen, low cigarette, fire-retardant, energy-saving and environment-friendly environment-friendly type copper core second the third insulating elastomer sheath is soft Cable.

In order to solve the above technical problems, the utility model uses following technical scheme：A kind of environment-friendly type copper core second third insulate Elastic body jacket flexible cable, including conductor, the conductor is coated with conductor clad and insulating layer, and forms insulated wire cores, Filled with filled layer, the insulated wire cores are coated with liner layer and outer jacket successively outside for internal clearance after insulated wire cores stranding.

Conductor described in the utility model is twisted into beam bare copper wire or tinned copper wire to be finely compound.

Conductor clad described in the utility model is attached most importance to lap wound bag double-layer high strength semiconductive nylon tape, and wrapped cap rate is not Less than 20%.

Insulating layer described in the utility model irradiates Insulation Material for LSOH anti-flaming second third.

Filled layer described in the utility model is LSOH anti-flaming high temperature packing rope.

Liner layer described in the utility model is LSOH anti-flaming glass cloth tape, and wrapped cap rate is not less than 20%.

Outer jacket described in the utility model is LSOH anti-flaming elastomer exposed material layer.

Compared with prior art, insulation performance and electric property are excellent, and service life is long for the utility model, Flame-retardant low-smoke, nothing Poison it is harmless, oil resistant, high temperature resistant, it is low temperature resistant, adapt to various severe operating environments.

Description of the drawings

Fig. 1 is the structure diagram of the utility model.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：As shown in Figure 1, the utility model environment-friendly type Copper core second the third insulating elastomer sheath soft cable, including conductor 1, conductor 1 is coated with conductor clad 2 and insulating layer 3, and group Into insulated wire cores, the internal clearance after insulated wire cores stranding is filled with filled layer 4, and liner layer 5 is coated with successively outside insulated wire cores With outer jacket 6.Wherein, conductor 1 is twisted into beam bare copper wire or tinned copper wire to be finely compound；Conductor clad 2 is attached most importance to lap wound Bao Shuan Floor height intensity semiconductive nylon tape, wrapped cap rate are not less than 20%；Insulating layer 3 is the irradiation insulation of LSOH anti-flaming second third Material, and be extruded in outside conductor clad 2；Filled layer 4 is LSOH anti-flaming high temperature packing rope, is filled up between entire insulating layer entirely The clearance space in portion；Liner layer 5 is LSOH anti-flaming glass cloth tape, and wrapped cap rate is not less than 20%；Outer jacket 6 is Halogen Low-smoke and flame retardant elastomer exposed material layer, and be extruded in outside liner layer.

The advantages of the utility model, includes：(1) insulation irradiates Insulation Material using LSOH anti-flaming second third, which has Halogen, low cigarette, flame-retarding characteristic, and temperature resistant grade reaches 150 DEG C；(2) insulation substitutes traditional steam using cross-linking radiation and hands over Connection, effectively prevents vapor from entering inside cable, protects the insulation performance and electric property of cable, and cross-linking radiation mainly utilizes The electron beam irradiation cable insulation that accelerator generates brings it about crosslinking, and vapor crosslinking using burning coal generation hot gas into Row crosslinking, the crosslinking method be easy to cause environmental pollution and influence health；(3) insulating materials need to only use common extrusion molding Machine extrudes, and without increasing special rubber extruding machine, saves equipment cost；(4) compared with cross-linked polyethylene insulated cable, the insulated cable In use, characteristic due to material in itself, insulating surface are not easy heap accumulated charge in straight-flow system, three-dimensional effect cause will not be generated Make decreasing insulating, reduce the service life of cable；And the material is more soft compared to crosslinked polyethylene insulation material, more Add suitable for mobile laying occasion；(5) cable jacket irradiates protective cover material using LSOH anti-flaming elastomer, which has (temperature resistant grade is to up to 150 for good resistance to ag(e)ing, oil resistivity, lower temperature resistance (reachable -42 DEG C of temperature resistant grade), heat-resisting quantity DEG C), Halogen, low cigarette, flame-retarding characteristic；(6) sheath material need to only be extruded using common extruding machine, without increasing special crowded rubber Machine saves equipment cost；(7) using cross-linking radiation mode, the various person and environmental hazard caused by burning coal are effectively avoided.
