(2)Using a base double loop cable termination tower, wire is hung using the unilateral wire cross-arm of double-loop terminal tower, and By wire jumper by wire around causing at cable termination, under realizing that overhead transmission line cable cut-offs and draws.But construction cost is higher, Column foot floor space is larger, cut-offs the arrangement mode of the perpendicular arrangement of place's wire hitch point and conventional triangular form or upper font not Together, cause adjacent tangent tower wire suspension string to deviate vertical state, when electric clearance is unsatisfactory for requiring, adjacent tower need to be carried out and changed Make, so as to construction cost and floor space is significantly increased.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model is provided and a kind of cut-off suitable for single time overhead transmission line cable Special steel tower, it is only necessary to realize that cable cut-offs using a base steel tower, construction cost is relatively low, and floor space is smaller, former circuit is not changed Arrangement mode, is adapted to neighbouring tangent tower construction, can be used as angle tower.
The utility model solves the technical scheme that is used of above-mentioned technical problem;
A kind of special steel tower cut-off suitable for single time overhead transmission line cable, including tower body, ground wire cross-arm, topping wire are horizontal Load, middle layer conductor cross-arm, lower floor aid in cross-arm, cable suspension support and fore-telling font cable to draw lower terminal.
The top of the tower body sets ground wire cross-arm, and both sides cross-arm is arranged from tower body horizontal path direction.
The topping wire cross-arm is installed on ground wire cross-arm lower section, and both sides cross-arm is arranged from tower body parallel circuit direction, in Cross-arm ending fixes phase conductor in strain insulator-string suspension, is fixed in cross-arm ending and foretells font cable termination.
The middle layer conductor cross-arm is installed on topping wire cross-arm lower section, in cross arrangement, from tower body horizontal path side To arrangement both sides cross-arm, strain insulator-string Pendent edge phase conductor is fixed in cross-arm ending, setting cable suspension support in cross-arm ending consolidates Surely font cable termination is foretold;Both sides cross-arm is arranged from tower body parallel circuit direction, setting cable suspension support in cross-arm ending fixes Foretell font cable termination.
Lower floor's auxiliary cross-arm is installed on middle layer conductor cross-arm lower section, in cross arrangement, from tower body parallel circuit side To arrangement both sides cross-arm, cable suspension support is set and is fixed in cross-arm ending and foretell font cable termination;From tower body horizontal path direction Arrangement both sides cross-arm, sets cable suspension support and fixes and foretell font cable termination in cross-arm ending.
The fore-telling font cable draws lower terminal and is made up of end, suspension insulator and arrester, horizontal positioned at topping wire Between load and middle layer conductor cross-arm, middle layer conductor cross-arm and lower floor auxiliary cross-arm.
The beneficial effects of the utility model:The single time overhead transmission line cable for being applied to small angle tower cut-offs and draws lower strain insulator Tower, it is only necessary to realize that cable cut-offs using a base steel tower, construction cost is relatively low, and floor space is smaller, former line arrangement side is not changed Formula, is adapted to neighbouring tangent tower construction, can be used as angle tower.
