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, form cable core by many insulated wire cores twisted synthesizing cables, 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, was wound around lapping layer outward at cable core, 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
The purpose of this utility model 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 utility model is taked is: a kind of cold-resistant resistance to fire-retardant wind energy power cable of turning round, be twisted into strand by some aramid fiber yarn conductor parts and some annealed copper wire conductor parts by certain pitch, be twisted into again in the same way flexible conductor by strand according to certain pitch 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.
