Abstract

Abstract: In order to develop a kind of lightweight, stable structure performance and durability of composite electric pole, this paper, based on the pilot project of mountainous environment in coastal area, starts with the load calculation of transmission electric pole under various working conditions, establishes the finite element analysis model, and carries on the structural design of composite electric pole. A 12 m long composite electric pole with two sections was prepared by small Angle cone-winding process using modified polyurethane as matrix material and glass fiber as reinforcement material. Mechanical true load performance evaluation and series of material aging test of the full-size electric pole were carried out. The results show that the composite pole with the insertion coefficient of 2.0 based on simulation meets the practical application requirements in terms of strength and deflection, and has excellent weather resistance. The segmented structure of the pole is smaller in size and lighter, which will greatly improve the convenience of construction and transportation and provide a new idea for the construction of distribution network lines.
