Load, lower double back wire cross-arm and bottom auxiliary cross-arm, the top layer ground wire cross-arm, upper double back wire cross-arm are vertical from tower body side
Both sides cross-arm is arranged in line direction, above-below direction is consistent；The lower double back wire cross-arm, bottom auxiliary cross-arm are in T font cloth
Put, above-below direction is consistent.
Cable suspension support is respectively connected with each ending of lower double back wire cross-arm, is all connected with each cable suspension support
There is fore-telling font cable to draw lower terminal.
The fore-telling font cable draws lower terminal and is made up of end, suspension insulator and spark gap, suspension insulator,
Spark gap is arranged vertically, and spark gap is located above suspension insulator.
Described upper double back wire cross-arm is three-decker, and every layer of cross-arm be from tower body side perpendicular to line direction cloth
Both sides cross-arm is put, above-below direction is consistent.
Described lower double back wire cross-arm is three-decker, and, in T fonts arrangement, above-below direction is consistent for every layer of cross-arm.
Beneficial effects of the present invention：The tower is applied to overhead transmission line corner, can be used as 45 degree of -90 degree of the corner number of degrees
Angle tower, can be used for four loop unilateral or bilaterals and cut-off, preferably adjacent to tangent tower construction, compare compared with scheme and save a base
Shaft tower, reduces construction cost, reduces floor space.
