Shaft tower, power transmission line, the first insulator and the second insulator, on the top of the shaft tower, from top to bottom sequentially interval is installed with
Cross-arm and auxiliary cross-arm, one end of the first insulator are hinged on cross-arm, and one end of the second insulator is hinged on auxiliary cross-arm,
The other end of first insulator and the second insulator is suspended on power transmission line, and the auxiliary cross-arm includes upper auxiliary cross-arm with
Cross-arm is aided in, has angle between upper auxiliary cross-arm and shaft tower, has angle between lower auxiliary cross-arm and shaft tower.
Here is the further optimization and/or improvements to foregoing invention technical scheme：
Angle between above-mentioned upper auxiliary cross-arm and shaft tower can be 60 degree to 75 degree.
Angle between above-mentioned lower auxiliary cross-arm and shaft tower can be 60 degree to 75 degree.
Reasonable and compact in structure of the present invention, it is easy to use, cross-arm is aided in here by upper auxiliary cross-arm and lower auxiliary cross-arm group
Into, and have angle between upper auxiliary cross-arm and shaft tower and between lower auxiliary cross-arm and shaft tower；In strong wind weather compared to biography
The servicing unit of system, the upper auxiliary cross-arm and lower auxiliary cross-arm that the present invention uses can effectively share shearing force caused by strong wind,
The steadiness of increase auxiliary cross-arm, effectively prevents from aiding in cross-arm to be blown down by strong wind, increases the stability of transmission line of electricity, reduce transmission of electricity
The frequency that circuit windage yaw tripping operation occurs.
