The top of the tower body arranges ground wire cross-arm, arranges both sides cross-arm from tower body horizontal path direction.
The topping wire cross-arm is installed on below ground wire cross-arm, arranges both sides cross-arm from tower body parallel circuit direction, in
Cross-arm ending fixes phase conductor during strain insulator-string hangs, and fixes in cross-arm ending and foretells font cable termination.
The middle layer conductor cross-arm is installed on below topping wire cross-arm, 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, cable suspension support is set in cross-arm ending solid
Surely foretell font cable termination；Both sides cross-arm is arranged from tower body parallel circuit direction, cable suspension support is set in cross-arm ending and is fixed
Foretell font cable termination.
Lower floor's auxiliary cross-arm is installed on below middle layer conductor cross-arm, 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, arranges cable suspension support and fixes in cross-arm ending and foretell font cable termination.
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.
Beneficial effects of the present invention：Should cut-off suitable for single time overhead transmission line cable of small angle tower and draw lower anchor support,
Only need to realize that cable cut-offs using a base steel tower, construction cost is relatively low, and floor space is less, does not change former line arrangement mode,
It is adapted to neighbouring tangent tower construction, can uses as angle tower.
