Transmission line tangent tower using double-loop cable T guide

2012 
The invention discloses a transmission line tangent tower using double-loop cable T guide and relates to the technical field of high voltage transmission lines. The tower comprises a tower body, an upper lead cross arm, a middle lead cross arm, a lower lead cross arm, a T connection upper cross arm, a T connection middle cross arm, a T connection lower cross arm and a T connection bottom cross arm, wherein a lightning arrester and a supporting insulator are arranged between every adjacent T connection cross arms which are on the upper portion and the lower portion respectively, the upper end of the lightning arrester is connected to the T connection cross arm on the upper portion, the lower portion of the lightning arrester is connected to the upper end of the supporting insulator, the lower end of the supporting insulator is connected to the T connection cross arm on the lower portion, and a cable terminal is connected to the connection position of the lightning arrester and the supporting insulator. Compared with the traditional strain tower T guide lower tower, the tangent tower is not required to be changed to the strain tower, the use quantity of steel materials and basic use quantity are reduced, the construction cost is saved, a lead cross arm insulator sting is in a V sting design, the lead windage yaw is effectively reduced and the line corridor width is reduced.
