Chinese patent once disclosed a kind of wind energy power cable (CN201220663495), comprise cable core conductor, inner covering, insulating barrier, protective layer, described cable core conductor comprises strand, described strand be by tinned copper wire according to regular stranded the forming of left-hand, described strand is according to the regular twisted synthesizing cable core conductor of dextrad; Described cable core conductor is disposed with inner covering, insulating barrier and protective layer outward.
Chinese patent once disclosed a kind of offshore wind power generation single-core power cables (CN201220598076) for machine, on conductor, extruded insulation layer forms insulated wire cores, surface in single insulated wire cores arranges the reinforced layer being woven into by filament, extrudes formation external sheath layer on reinforced layer; Conductor be adopt multiply tin-coated copper thread strand and multiple strand regular in the same way stranded and form.
Chinese patent once disclosed a kind of offshore wind power generation multi-core power cable (CN201220598322) for machine, on conductor, extruded insulation layer forms insulated wire cores, by many insulated wire cores twisted synthesizing cables, form cable core, on cable core, set gradually from inside to outside and extrude the inner covering of formation, the reinforced layer that filament braiding forms and the external sheath layer that extrudes formation; Conductor be adopt multiply tin-coated copper thread strand and multiple strand regular in the same way stranded and form.
Chinese patent once disclosed a kind of low-temperature wind-energy power cable (CN201220348281), comprised cable core, at cable core, was wound around lapping layer outward, and outermost layer extrudes restrictive coating, and the rubber packing extruding between several wire core and core is twisted into cable core; Described core is by the overlapping wrapped isolation strip of stranded conductor outer surface, and outside isolation strip, extruded insulation layer forms again.
Summary of the invention
What the object of the present invention is to provide a kind of fire-retardant, oil resistant, UV resistant, corrosion-resistant, low temperature resistant, resistance to twisting property excellence cold-resistant resistance toly turns round fire-retardant wind energy power cable, to ensure the performance requirement of power cable for wind energy generation.
For achieving the above object, the solution that the present invention takes is: a kind of cold-resistant resistance to fire-retardant wind energy power cable of turning round, by some aramid fiber yarn conductor parts and some annealed copper wire conductor parts, by certain pitch, be twisted into strand, by strand, according to certain pitch, be twisted into again in the same way flexible conductor again, the flexible conductor being twisted into again in the same way by strand is outer by certain wrapped isolation strip of the rate of putting up, extruded insulation outside isolation strip extrudes sheath outside insulation.
Described insulation 5 utilizes rubber extruding machine to extrude according to certain thickness and forms outside isolation strip 4, and its material is ethylene-propylene rubber.
Described sheath 6 utilizes plastic extruding machine to extrude according to certain thickness and forms outside insulation 5, and its material is polyurethane.
Compared with the prior art, the technological improvement of this cable is embodied in:
1, adopted a kind of novel conductor structure, adopted some aramid fiber yarns and some annealed copper wires to be twisted into strand by certain pitch, then according to certain pitch, be twisted into again in the same way flexible conductor by strand.This high strength aramid fiber yarn that increases in the middle of strand also adopts and is twisted into again in the same way the conductor structure of flexible conductor, makes wind energy cable when being subject to the mechanical stress effects such as frequent bending, torsion, has higher than the counter-bending of conventional wind energy cable and anti-torsion performance; This increase high strength aramid fiber yarn in the middle of the strand and adopt be twisted into again in the same way the conductor structure of flexible conductor, the external diameter of wind energy cable is reduced and pliability is enhanced.
