The utility model discloses a mountain area anti-pull up power transmission line tangent tower adopting glass fiber reinforced plastic inverted V-shaped strings. The tangent tower comprises a tower body, a ground wire support, upper cross arms, middle cross arms, lower cross arms, and glass fiber reinforced plastic inverted V-shaped strings. The tower body is provided with the ground wire support, the upper cross arms, the middle cross arms, and the lower cross arms. Each of the glass fiber reinforced plastic inverted V-shaped strings is constituted by a cylindrical-shaped glass fiber reinforced plastic insulating rod, a connecting plate, and a suspension wire clamp. Z-shaped hanging plates used for lower ends of two branch strings of each of the lass fiber reinforced plastic inverted V-shaped strings are respectively connected with the suspension wire clamp of the corresponding upper cross arm, the suspension wire clamp of the corresponding middle cross arm, the suspension wire clamp of the corresponding lower cross arm. The mountain area anti-pull up power transmission line tangent tower is advantageous in that the anti-pressure performance and the anti-insulation performance of the glass fiber reinforced plastic materials are combined with the bearing characteristics of the inverted V-shaped strings, and then the shedding or the damaging of the common suspension strings are prevented, and therefore the windage yaw of the leads on the tower head parts can be effectively limited, and the electric clearance distance can be guaranteed.
