Abstract
The utility model discloses a flexible cable specialized for wind power generation, which comprises an outer protective layer and three cores wrapped inside the outer protective layer. The outer protective layer is composed of a polyether type thermoplastic polyurethane compound sheath and a wrapping tape which are sequentially arranged from the outside in. Each core is formed by wrapping a conductor through an EP rubber type elastomer insulating layer. The flexible cable is characterized in that each conductor is formed by twisting a plurality of tin-plating annealed copper wires; and a shielding layer is arranged among the sheath and the cores. The shielding layer has a three-layer structure. The inner layer is composed of aluminum magnesium alloy wires. The middle layer is composed of plastic-aluminum composite films. The outer layer is composed of iron nickel alloy belts. Preferably, two high-strength steel wires parallel to each other and arranged along the vertical direction of the cable are arranged on the sheath wall thickness central positions. The cable which achieves greater strength is not prone to core breaking and electromagnetic interference generation.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of wind power generation Special flexible cable.
Background technology
Wind energy cable is mainly used in the connecting line of blower fan, the environment for use very severe, not only to have excellent electric property and anti-torsion performance, the characteristics such as excellent wear-resisting, cold-resistant, oil resistant, water-fast, ageing-resistant, high water proofing property, poisture-penetrability, windproof, weather-resistant, antibiotic, mildew-resistant, environmental protection also will be arranged.The flexible cable that uses at wind-driven generator at present mostly is common flexible cable, can't fully meet the harsh requirement of cable environment for use, is prone to the quality problems such as disconnected core, cracking, and cable is short useful life, affects the efficiency of blower fan system.Therefore, the research and development used for wind-energy power generation flexible cable of anti-the torsion also promotes its specialization and seriation, guarantees the operation of the long-term stability of wind energy cable, has positive social progress meaning and economic development prospect.For this reason, Chinese patent CN201220289504.6 discloses a kind of used for wind-energy power generation flexible cable of anti-the torsion, comprises external protection and is wrapped in three cores in external protection; Described external protection is comprised of polyether-type thermoplastic polyurethane compound sheath and band from outside to inside; Every core is comprised of the elastic body insulated layer parcel of ethylene-propylene rubber type conductor.The advantage of this technical scheme is by the improvement of the type selecting of the structural design to cable, material, has improved anti-twisting property, weatherability, lower temperature resistance and the Corrosion Protection of cable, has strengthened the use safety of cable, the useful life of having improved cable.But, also exist one obviously not enough, that is: insufficient strength, easily broken core, be applied in electronic equipment produce sometimes electromagnetic interference.
The utility model content
The purpose of this utility model is to provide a kind of wind power generation Special flexible cable of new construction, and not only intensity is better for it, and not easily broken core is difficult for producing electromagnetic interference.
for realizing this purpose, the technical solution of the utility model is: a kind of wind power generation Special flexible cable, comprise external protection and be wrapped in three cores in external protection, described external protection is comprised of polyether-type thermoplastic polyurethane compound sheath and band from outside to inside, every core is comprised of the elastic body insulated layer parcel of ethylene-propylene rubber type conductor, described conductor adopts some stranded the forming of tin annealed copper wire bundle, between described sheath and core, be provided with screen, described screen is three-decker, internal layer is aluminum-magnesium alloy wire, intermediate layer is plastic-aluminum combined film, skin is the iron-nickel alloy band.
As preferably, described sheath wall thickness middle position is provided with two high-tensile steel wires that are parallel to each other and arrange along the cable longitudinal direction.
As preferably, the synthetic fibers filler is arranged in the space between described external protection and core.
As preferably, between described polyether-type thermoplastic polyurethane compound sheath and band, also be provided with the anti-layer of turning round of an aramid fiber braiding.
With respect to prior art; the utility model filled core adopts the aramid fiber yarn that percentage elongation is little, tensile strength is large, flexible, not combustion-supporting, corrosion-resistant and line density is little; percentage elongation is little, tensile strength is greatly in the situation that cable is stressed; cable has been played to protective effect, guaranteed the transmission quality of cable, be filled in the gap of cable after stranded aramid fiber yarn; improved the pull-off force of cable; the firm structure of cable, transmit cable, more stable quality in special environment.In the wall thickness middle position setting of sheath, by the high-tensile steel wires of two parallel placements, form tension member, help to promote cable intensity, when cable bears larger pulling force, can play correct protective effect to core.adopt aluminum-magnesium alloy wire, three layers of composite shielding structure of plastic-aluminum combined film and iron-nickel alloy band, almag is placed on to innermost layer, a little less than utilizing its magnetic, the characteristics that density is little, can not produce interference and effectively alleviate cable weight, and the iron-nickel alloy band is a kind of strong magnetic material, can effectively overcome the interference of high-intensity magnetic field, using plastic-aluminum combined film as in ask that layer can effectively shield on the one hand, also can isolate on the other hand aluminum-magnesium alloy wire and iron-nickel alloy band, prevent that both from producing coupling effect, influence each other and offset magnetic screen, greatly promoted electromagnetic pulse-resisting performance of the present utility model.
The accompanying drawing explanation
Fig. 1 is the utility model cross-sectional view.
Wherein: 1 is conductor; 2 is the elastic body insulated layer of ethylene-propylene rubber type; 3 is the synthetic fibers filler; 4 is band; 5 is polyether-type thermoplastic polyurethane compound sheath; 6 is screen.
