Abstract
The utility model discloses a TPE insulated sheath copper wire screening flexible cable, which belongs to a power transmission cable and comprises an insulated layer (2), at least a flexible conductor (1), and an outer sheath (6) sheathed on the outmost part of the cable; the insulated layer (2) integrally covers the flexible conductor (1); a cable forming cladding (3) is arranged inside the outer sheath (6); a screening layer (4) is disposed between the cable forming cladding (3)and the outer sheath (6); and a lead wire (5) is disposed between the cable forming cladding (3) and the screening layer. The special polyurethane polymer outer sheath for wind power generation has advantages of good insulating properties, corona resistance, electric arc resistance, good flame-retardant performance, chemical attack resistance, good mildew resistance, and ozone and ultraviolet ray resistance, and maintains stable electric insulating properties when the temperature and the frequency changes or sheath is wetted. The TPE insulated sheath copper wire screening flexible cable has simple structure, and is suitable for industrial production and is easy for popularization.
Description
Technical field
The utility model relates to power transmission cable, a kind of TPE insulating sleeve copper wire shielded flexible cable of saying so more specifically.
Background technology
Wind-powered electricity generation is the renewable new forms of energy of environment-protecting clean, and national industrial policies are first developed energetically.In wind generator system, cable is the vitals of power transfer, signal transmission and drag chain control, be installed in the environment of awful weather with wind power plant, require cable to have performances such as excellent low temperature resistant, high temperature resistant, high flexibility, tear-proof, antitorque commentaries on classics, in-40 ℃～90 ℃ environment, keep performance constant, simultaneously can be in low temperature environment tear-proof, can bear the requirement (3000 times that the high load capacity under the high drop condition continues to reverse, each positive and negative 3 weeks of reversing), to guarantee the normal operation of wind generator system.The serious electromagnetic interference of ubiquity in wind generator system influences the normal use of cable simultaneously, has limited to the generating efficiency of whole wind force generating system, security incident also easily takes place, thereby require cable to possess interference free performance.
There is the limitation on some aspect performance in control cable such as employed rubber, crosslinked polyethylene in the present wind generator system, its combination property all can not reach above-mentioned requirements, and all be thermoset cross-linked material, these materials are difficult for degraded, not recyclable, become one of main discarded object of following electric wire, it is buried or burn contaminated environment that the overwhelming majority is used as industrial waste.
Thermoplastic elastomer (TPE) (TPE) is a kind of high-quality and callable " green material ", is adopted by increasing industry at present.The serious electromagnetic interference of ubiquity in wind generator system has influenced the normal use of cable simultaneously, has limited to the generating efficiency of whole wind force generating system, and security incident also easily takes place.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency, and providing a kind of is insulating material with thermoplastic elastomer (TPE) (TPE), and has the TPE insulating sleeve copper wire shielded flexible cable of screen.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
TPE insulating sleeve copper wire shielded flexible cable of the present utility model, comprise insulating barrier and at least one flexible conductor, and be sleeved on the outermost oversheath of cable, insulating barrier is with the flexible conductor integral coating, there is the stranding lapping layer oversheath inside, also is provided with screen between oversheath and the stranding lapping layer, is provided with drainage thread between stranding lapping layer and the screen, drainage thread can lead to electromagnetic interference the oversheath outside fully, avoids the flexible conductor in the cable to be affected; Described insulating barrier is the TPE insulating barrier.
Further technical scheme is: described oversheath is a wind power generation special polyurethane polyureas zoarium.
Further technical scheme is: described flexible conductor is the naked copper flexible conductor.
Further technical scheme is: described cable lapping layer is a reinforced light non-woven fabrics.
Further technical scheme is: described drainage thread is a tinned copper wire, and screen is that tinned copper wire is made.
Compared with prior art, the beneficial effects of the utility model are: under the screen in the TPE insulating sleeve copper wire shielded flexible cable and the cooperation of drainage thread, can stop the influence that electromagnetic interference causes cable in the wind generator system fully, TPE can still keep good pliability under-60 ℃ low temperature environment simultaneously, the fit oversheath of wind power generation special polyurethane polyureas has good insulation performance performance and anti-corona and arc resistance, in temperature and frequency change or when making moist, it is stable that electrical insulation capability can keep, also has good flame-retarding characteristic, can anti-chemically corrode, have good mildew resistance, and anti-ozone, antiultraviolet etc.The TPE insulating sleeve copper wire shielded flexible construction of cable of the present utility model is simple simultaneously, is suitable for suitability for industrialized production, is easy to promote.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, TPE insulating sleeve copper wire shielded flexible cable of the present utility model, outermost layer is the fit sheath of making 6 of wind-driven generator special polyurethane polyureas, the inboard of sheath 6 is with the screen 4 of the high density braiding structure that adopts the tinned copper wire making, screen 4 inboards are with stranding lapping layer 3, a drainage thread 5 is set between screen 4 and the stranding lapping layer 3, keeps well contacting with screen 4.There are eight bare copper conductors 1 that are with insulating barrier 2 inboard of stranding lapping layer 3, and bare copper conductor 1 is the multicore fine copper wire, and insulating barrier 2 is made for the extraordinary thermoplastic elastomer (TPE) (TPE) of wind-driven generator special use.
During making, adopt the synnema machine to carry out the strand system of strand, on bare copper conductor 1, extrude wind-driven generator special rubber elastomer (TPE) insulating barrier 2 with plastic extruder, online detection simultaneously, carry out right stranded of insulated wire with pair twister, make stranding lapping layer 3 with cabler at stranded skin, with braiding machine tinned copper wire is woven into screen 4 on stranding lapping layer 3, make drainage thread 5 simultaneously, on screen 4, extrude the polymeric sheath 6 of one deck wind-driven generator special polyurethane with extruder at last.
