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 arrester, suspension insulator,
Arrester is arranged vertically, and arrester is located at suspension insulator top.
Described upper double back wire cross-arm is three-decker, and every layer of cross-arm is 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 every layer of cross-arm arranges that above-below direction is consistent in T fonts.
Every layer of upper double back line conductor cross-arm utilizes both sides cross-arm wire, every layer of lower double back wire cross-arm to be hanged using both sides cross-arm
Transmission line of electricity corner outboard wire is hung, every layer using one side cross-arm suspension transmission line of electricity corner inboard wire.
The beneficial effects of the utility model：The tower is applied to overhead transmission line corner, can as 45 degree of the corner number of degrees-
90 degree of angle tower, can be used for four loop unilateral or bilaterals and cut-offs, and preferably adjacent to tangent tower construction, is compared compared with scheme and saved
One base shaft tower, reduces construction cost, reduces floor space.
