Clamp steel cap, described cross-arm bearing are fixedly connected with exterior wall, and described clamp steel cap is fixed with insulating bar.Clamp steel cap is used for
Insulating bar is socketed, plays fixation.
In a kind of preferable scheme, the central point of described overhead transmission line protector is when generation maximum wind power
When the minimum hidden danger point of exterior wall and conductor spacing.Such setting at utmost protection equipment from the influence of wind-force, can drop
Low failure risk.
In a kind of preferable scheme, the distance between described insulating bar and insulating bar are identicals.
Compared with prior art, the beneficial effect of technical solutions of the utility model is：The utility model provides a kind of new
The overhead transmission line protector and system for windage yaw, the wind for leading the electric discharge of Line To Line row of channels both sides buildings can be reduced
Inclined flashover fault, the safety and the people's lives and property safety of transmission facility are ensured, reduces the generation of tripping fault.
