Abstract

Abstract: In economically developed urban areas, there is a conflict between tight land supply and land acquisition for transmission lines. To solve the problem, this work research developed a composite insulating compact tower with a rocket-like shape, in which the wires pass through the inside of the insulating composite tower, compressing the width of the line corridor to the greatest extent. The mechanical properties of the 110 kV composite rocket tower were simulated and calculated, and truly experimental mechanical tested. The research results showed that the 110 kV composite rocket tower with a root opening of 1.8 meters and height of 19 meters had passed 100% design load tests under four operating conditions, including normal operation, disconnect the wire, 90° wind and uneven icing. There was no abnormality in all parts of the tower. The true mechanical test result was highly consistent with the simulation result of the tower, and the maximum deformation of the tower body occurred in the root area of the rocket tower, and the corresponding maximum deformation of the main rod was located in the root area of the rocket tower. Under the condition of nonuniform icing, the end displacement of the rocket tower was the largest, and the maximum displacement was 48 mm, which met the design requirements of the 110 kV tower.

Key words: rocket tower, composite material, tight corridor, mechanical properties, simulation calculation
