SUPPORT STRUCTURE FOR OVERHEAD HIGH-VOLTAGE AND SUPER-VOLTAGE TRANSMISSION LINE Russian patent published in 2007 - IPC E04H12/00 

FIELD: construction, particularly towers, masts, poles, chimney stacks, water-towers and methods of erecting such structures, namely support structures for high-voltage transmission lines.

SUBSTANCE: support structure comprises mast with upper and lower bracket arms connected to the mast and adapted for cable retention. Lower mast end is divided into two sections in direction transversal to transmission line axis. Each above mast section defines inclined masts supported by separate foundation. Support structure also has ground wire peak to provide necessary lightning protection of transmission line cable. The inclined masts are rigidly connected to lower end of upper mast section at height below lower bracket arm connection height. All masts are symmetric or non-symmetric about transmission line axis. Upper mast section located between lower and upper bracket arms is inclined with respect to vertical axis passing through connection area, which connects inclined masts with lower end of upper inclined mast section and is extension of one inclined mast. Ground wire peak is parallel or inclined with respect to above vertical axis passing through connection area, which connects inclined masts with upper inclined mast section.

EFFECT: decreased metal consumption along with increased reliability of transmission line operation under wind force to be applied obliquely to transmission line axis in operation conditions and decreased transmission line corridor width.
