Further, the interior one end near the first annular slab of the elongated hole of channel-section steel is fixedly connected with fabric wheel.
Further, pre-twist wheel is provided with many groups along the length direction of elongated hole, and the wheelspan L1 between two adjacent groups pre-twist wheel is: L1=L/2+(10 ~ 15) mm, wherein L is the pitch of twisted wire.
Further, the distance L2 between deconcentrator and wire parallel module is: L2=L+(20 ~ 35) mm, wherein L is the pitch of twisted wire.
Further, the diameter of pre-twist wheel is 25mm ~ 30mm.
Compared with prior art, beneficial effect of the present invention is:
The present invention sets up pre twist between body and deconcentrator, this pre twist is made up of one or more groups pre-twist wheel, by pre-twist wheel, a prestressing force is applied to steel wire, and adopt and stranded identical pitch, first make steel wire produce certain plastic deformation, thus be twisted into " S " type, reduce the elastic restoring force that steel wire produces after strand system, thus can not produce when laying and split seam and loose stock phenomenon, and the structure of steel reinforced aluminium conductor more closely, rounding and stablizing.
