Description
Technical field
The utility model belongs to control cables technical field, especially a kind of resistance to torsion anti-interference blower fan tower bucket control cables.
Background technology
Current antitorque transition, cable was mainly main material production with conventional rubber, its structure is that stranded conductor outer cladding polyester belt or nonwoven fabrics are as separator, the insulation of ethylene-propylene rubber type is extruded outside separator, affix screen, and extrude sheath and make, the insulating barrier of this cable and restrictive coating need through loaded down with trivial details vapour cure cross-linking process, production process is loaded down with trivial details, and the mechanical performance of cable, fire-retardant and oil resistance is poor, weatherability is bad, conductor is oxidizable, useful life is short, easily adhesion is there is under the high-temperature condition of 110 DEG C ~ 150 DEG C, impact is normal to be used, in addition, existing anti-torsion cable is only applicable to low electric field, work under downfield, at this high electric field of wind generator tower bucket, when working under the adverse circumstances interference of highfield, easy generation signal transmission is unstable and can not use.
Summary of the invention
The purpose of this utility model be exactly there is bad mechanical property for cable existing antitorque transition, fire retardant oil resistance is poor, weatherability is bad, conductor is oxidizable and the problem that cannot use under high electric field, highfield condition, provides a kind of resistance to torsion anti-interference blower fan tower bucket control cables.
The utility model is a kind of resistance to torsion anti-interference blower fan tower bucket control cables, it comprises cable core and sheath, particularly: described cable core is made up of three strands of twisted wires, per share twisted wire is made up of two linear conductors, every root conductor is made up of the ethylene propylene rubber insulated layer of bare copper wire outer cladding cross-linking radiation, outside wrapped aluminium-plastic tape after every two conductor pair twists, aluminium-plastic tape outer cladding tinned copper wire woven shield forms twisted wire, wrapped polyester belt successively from inside to outside after three strands of twisted wire assembly cable cores, tinned copper wire braid shielded, nonwoven fabrics and sheath, described sheath is made up of cross-linking radiation haloflex.
Bare copper wire described in the utility model forms by soft copper monofilament is stranded, every 1.0mm
2stranded in scope have 32 soft copper monofilament, and described soft copper filament diameter is 0.2mm.
The thickness of the ethylene propylene rubber insulated layer of cross-linking radiation described in the utility model is 0.6mm, the thickness of aluminium-plastic tape is 0.025mm, tincopper fuse wire braided armor filament diameter is 0.12mm, the thickness of polyester belt is 0.05mm, nonwoven thickness is 0.1mm, and cross-linking radiation chlorinated polyethylene sheath layer thickness is 2.0mm; Described control cables external diameter≤18mm.
Conductor of the present utility model adopts 5 class formations (adopt five class conductors in GB/T 3956-2008 standard, this type of conductor has excellent flexibility), is convenient to product and is used in mobile occasion; Insulating barrier adopts the cross-linking radiation ethylene-propylene rubber material of superior performance, restrictive coating adopts cross-linking radiation haloflex material, do not need special rubber extruding machine vulcanizing equipment, but adopt electron accelerator to carry out cross-linking radiation process to insulating barrier and restrictive coating, make plastic body be become the network structure be connected layer by layer by chain structure, thus drastically increase the combination property of cable product; Aluminium-plastic tape protection insulating barrier, from braided wires scratch, plays shielding action simultaneously; Zinc-plated braided wires has shielding action, can electromagnetism interference; Nonwoven fabrics protection restrictive coating, from braided wires scratch, can strengthen the resistance to twisting property of cable simultaneously.
The relatively existing resistance to torsion cable of the utility model has the following advantages:
(1) temperature resistant grade brings up to 105 DEG C from 90 DEG C, and under identical service condition, the raising of its temperature resistant grade, makes current-carrying capacity of cable lifting, fail safe enhancing, useful life increase;
(2) have good mechanical performance, the intensity of material is improved, and has good resistance to twisting property and bending resistance;
(3) there is excellent weatherability, low temperature resistantly reach-55 DEG C, and oil resistant, ozone resistance are improved, and have widened the use occasion of cable;
(4) there is good anti-electromagnetic interference capability, ensure that the stability of signal in cable;
(5) conductor oxidation resistent susceptibility promotes greatly.
The utility model solves the existing bad mechanical property of resistance to torsion cable, fire-retardant and oil resistance, weatherability are poor, conductor is oxidizable, the problems such as useful life is short, adhesion is there is not under the high-temperature condition of 110 DEG C ~ 150 DEG C, do not ftracture under-55 DEG C of severe low temperature environments, and there is excellent anti-electromagnetic field jamming performance, can effectively suppress and weaken strong electromagnetic, be particularly useful for working in wind generator tower bucket.
