Abstract
The invention relates to an environment-friendly cable for power generation. A soft copper wire bundle is twisted into a braided wire and then the braided wire is re-twisted. During re-twisting, the twisting directions of adjacent two braided wires of each layer are opposite; the layers are twisted in the same direction, and an internal opening polycrystalline drawing die is used for compacting and forming; the conductor is covered by silicon rubber materials serving as an insulating layer; an external sheath is compacted and extruded by a low-smoke and halogen-free fire-retardant rubber material. The environment-friendly cable for power generation has the advantages that: the conductor of the cable has automatic restorability and properties such as torsion resistance, low-temperature resistance, corrosion resistance, oil resistance, aging resistance, radiation resistance and environment friendliness can be improved.
Description
Technical field
The invention belongs to the cable technology field, is a kind of wind electric power generation cable that is used for the comparatively abominable area of weather conditions.
Background technology
Because wind electric power generation cable is used in the comparatively abominable area of weather conditions more, the general northern area that is used in China, weather cold more, and day and night temperature is bigger, cable must satisfy ambient temperature-45 ℃～+ 50 ℃, and operating temperature is-40 ℃～+ 50 ℃ a service condition.And cable because of long-time running in outdoor, the vertical unsettled influence of laying, frequently reverse (driftage is to wind automatically), contact greasy dirt (part), seawater corrosion abominable factors such as (particular surroundingss), the conductor structure of common wind electric power generation cable adopts soft copper tow strand form more, and insulation and outer jacket adopt the General Purpose Rubber material to extrude.Its resistance to torsion of the cable of this structure is poor, uses the conductor of cable loose easily for a long time, and insulation and sheath material can't satisfy environment for use.Cause damage, cause cable fault to take place.
Summary of the invention
Problems such as the present invention solves mainly that the resistance to torsion of cable is poor, useful life is low, low temperature resistant, corrosion-resistant, oil resistant, ageing-resistant, radiation hardness environmental protection.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of environmental protection wind electric power generation cable, the soft copper tow is twisted into strand, again strand is twisted again, the strand of every layer of two adjacent strand is on the contrary when twisting again, adopt stranded in the same way between layer and the layer, and press moulding through internal orifice glomerocryst drawing-die, and conductor coats silastic material outward as insulating barrier, and outer jacket adopts the LSOH anti-flaming elastomeric material closely to extrude.
The soft copper tow is twisted into strand, strand is twisted again again, the strand of every layer of two adjacent strand adopts strandedly in the same way on the contrary when twisting again between layer and the layer, and warp presses mould molding with the glomerocryst less than conductor diameter 2%.
The silastic material that closely extrudes low temperature resistant, corrosion-resistant, oil resistant on conductor thread core is as insulating barrier.
With the stranded stranding of the insulated wire cores that extrudes, tamp with suitable packing material between core, and tighten with belt.
Outer jacket adopts the LSOH anti-flaming elastomeric material closely to be extruded on the cable conductor.
Of the present inventionly have a mind to effect: characteristics such as the conductor of cable has self-restorability, improved the resistance to torsion of cable, low temperature resistant, corrosion-resistant, oil resistant, ageing-resistant, radiation hardness environmental protection.
