Cut-off angle steel tower for single-loop power transmission line
The invention discloses a cut-off angle steel tower for a single-loop power transmission line. The cut-off angle steel tower comprises a tower body, a top-layer ground wire cross arm, an upper-layer guide wire cross arm, a middle-layer guide wire cross arm and a lower-layer guide wire cross arm, wherein the top-layer ground wire cross arm is provided with a two-sided cross arm perpendicular to a target cut-off line direction from the tower body, and provided with a two-sided cross arm parallel to the target cut-off line direction from a tip part of an cut-off side cross arm; the upper-layer guide wire cross arm is provided with a two-sided cross arm parallel to the target cut-off line direction from the tower body; the middle-layer guide wire cross arm is T-shaped, is provided with a two-sided cross arm parallel to the target cut-off line from the tower body, and provided with a one-sided cross arm back on to a cut-off side and perpendicular to the target cut-off line from the tower body. The cut-off angle steel tower adopts a base pole tower to realize single-loop cut-off and reduce quantity of newly-built tower rods; and after the line is cut off, double loops are formed to continuously arrange the line, thereby avoiding use of a double-loop branch tower, not changing a guide wire arrangement mode of adjacent pole towers and reducing modifying possibility of adjacent towers.
