Angle is in 45 degree；Line-styled cross-arm is located at " X " type cross-arm ending, is vertically arranged both sides cross-arm with transmission line of electricity direction, separate
It is provided with A seating arrester on the line-styled cross-arm of steel tower, it is whole that A seating cable is provided on the line-styled cross-arm of steel tower
End；
Described to draw lower shaft tower include shaft, support insulator, and the shaft is close to built anchor support, the support insulator
From shaft top to independent cushion cap equidistant placement several layers, both sides, parallel circuit direction and back are arranged in every layer of horizontal path direction
It is arranged on one side to built anchor support.
Further, the A seating cable termination is arranged three altogether, is equally spaced in rack platform close to built anchor support
Inside line-styled cross-arm on.
Further, the A seating arrester is arranged three altogether, is equally spaced positioned at rack platform far from built anchor support
Outside line-styled cross-arm on.
Further, the support rod two sides have been placed equidistant with ladder.
Compared with prior art, the utility model has the beneficial effects that 1) cable draw lower special pole be suitble to be close to anchor support build
If；2) realize that single loop T connects, cut-offs and the multiple functions such as reconfiguration；3) do not change and draw downside anchor support stress, avoid old tower
It removes and rebuilds；4) compared with newly-built straight line, anchor support, construction cost is greatly reduced, reduces occupied area；5) dry core cable is used
Terminal structure is compared, and it is more extensive to be applicable in voltage class；6) it using independent cushion cap and the split type structure for drawing lower shaft tower, separately constructs
Reduce the influence to built route；7) independent cushion cap is used, keeps cable termination position lower, more conducively operation and maintenance.

[specific embodiment]
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1-3, a kind of cable for built single time anchor support draws lower facility, by independent cushion cap and draw lower shaft tower
Two parts composition.
The independent cushion cap includes support rod 1, rack platform 2, A seating cable termination 3, A seating arrester 4.
Rack platform 2 is arranged on 1 top of support rod, is made of " X " type cross-arm and line-styled cross-arm, in " X " type cross-arm
The heart is located at 1 top of support rod, is in 45 degree with transmission line of electricity angular separation；Line-styled cross-arm is located at " X " type cross-arm ending, and defeated
Electric line direction is vertically arranged both sides cross-arm.
" X " type cross-arm and transmission line of electricity angle are in 45 degree, top be used to support line-styled cross-arm, A seating cable termination 3,
A seating arrester 4, center are located at 1 top of shaft, provide fulcrum for shaft 1；Line-styled cross-arm is located at " X " type cross-arm ending,
It is vertically arranged both sides cross-arm with transmission line of electricity direction, the cross-arm far from steel tower is for fixing A seating arrester 4, close to the cross of steel tower
Carry on a shoulder pole fixed A seating cable termination 3, when built double loop strain insulator steel tower cut-offs scheme, can be subtracted with reducing cable and steel tower distance
Few cable kilometer, reduces project cost.
