Abstract
The utility model relates to a torsion-resistant cold-resistant antiflaming power cable applied to wind power generation. The cable comprises a tinned soft conductor and an insulation layer and a jacket layer are arranged outside the tinned soft conductor; the tinned soft conductor comprises more than 20 strands of wires, and each strand of wire comprises more than 20 lines of tinned copper wires involving four layers which are twisted, wherein the twisting direction of each layer of the tinned soft conductor is identical to the direction of strands; the insulation layer material is silicon rubber; and the jacket material is thermoplastic polyether-urethane. The torsion-resistant cold-resistant antiflaming power cable has the following beneficial technique effects: 1. the conductor structure is redesigned in the way that the twisting is carried out layer by layer and towards the same direction, especially towards the left, which is identical to the direction of strands so as to lead the wind power cable to pass the torsion test of 1440 DEG C/10000 times; and 2. the silicon rubber is adopted as the insulation material and the thermoplastic polyether-urethane is adopted as the jacket so as to lead the cable to pass the low-temperature torsion test carried out at minus 60 DEG C.
Description
Technical field
The utility model relates to the used for wind power generation cable.
Background technology
The conductor structure that the used for wind power generation power cable adopts usually is that layer-stranding, outermost layer strand are to twisting to opposite configuration, with 240mm for left-hand, each adjacent layer
2Be example: 37 strands are carried out layer-stranding by the 1+6+12+18 structure, and outermost layer is that 18 strands of layers are that left-hand is stranded, and inferior skin is that 12 strands of layers are that dextrad is stranded, and 6 strands of layers are that left-hand is stranded.Such conductor structure under carrying out normal temperature during the torsion test of 1440 °/10000 times (reversing negative 4 circles of positive 4 circles is 1 time), disconnected easily core.The used for wind power generation power cable adopts second third glue to insulate usually, adopts PCP or CPE to make sheath, and such structure can only be-25 ℃ low temperature torsion test.
Summary of the invention
In order to solve the problem of the easily broken core of used for wind power generation power cable, the utility model provides a kind of used for wind power generation anti-twist cold-resistant flame-proof power cable.
The anti-twist cold-resistant flame-proof power cable of used for wind power generation comprises zinc-plated flexible conductor, and its outside is insulating barrier and restrictive coating, and described zinc-plated flexible conductor comprises the wire harness more than 20 strands, and per share wire harness comprises the tinned copper wire more than 20, and is divided into four layers of stranded composition.Every layer of direction of lay of described zinc-plated flexible conductor is identical, and consistent with the strand direction; Described insulating layer material is a silicon rubber; Described sheath material is thermoplastic polyether polyurethane (TPU).
Useful technique effect of the present utility model: 1, in order to make the wind-force cable can be by following 1440 °/10000 times torsion test of normal temperature, we redesign its conductor structure: adopt layer-stranding, each layer strand is left-hand and the conductor structure consistent with the strand direction to identical.2, for guarantee low temperature torsion test that cable can be by-60 ℃ we adopt silicon rubber to do insulation, thermoplastic polyether polyurethane is made sheath.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
