Cross-arm on be provided with A seating arrester, be provided with A seating cable termination, the A seating on the cross-arm of lower beam tower bar body close to drawing
Cable termination is arranged three altogether, is equally spaced in rack platform on the inside line-styled cross-arm for drawing lower shaft tower, the seat
Formula arrester is arranged three altogether, is equally spaced positioned at bracket Pingyuan County from the outside line-styled cross-arm for drawing lower shaft tower；
Described to draw lower shaft tower include shaft, support insulator, auxiliary cross-arm, and the shaft is described close to built anchor support
Auxiliary cross-arm is parallel to line direction, the equidistant placement several layers near shaft top to independent cushion cap, the support insulator
From equidistant placement near shaft top to independent cushion cap, horizontal path direction is disposed with support insulator towards two sides along shaft,
Horizontal path direction is also disposed with support insulator towards two sides along auxiliary cross-arm taper.
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) using dry type electricity
Cable 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, separates
Construction reduces 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 Figs 1-4, a kind of cable for built double back anchor support draws lower facility, by independent cushion cap and draws 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 in above the cross-arm on 2 top of support rod, is made of " X " type cross-arm and line-styled cross-arm,
" X " type cross-arm and transmission line of electricity angle are in 45 degree, and it is lightning-arrest that top is used to support line-styled cross-arm, A seating cable termination 3, A seating
Device 4, center are located at the top of support rod 2, provide fulcrum for support rod 2, and line-styled cross-arm is located at " X " type cross-arm ending, and defeated
Both sides cross-arm is arranged in parallel in electric line direction, is used to fix A seating arrester 4 far from the cross-arm for drawing lower beam tower bar body 6, close to draw
