Facing increasing problems due to aging and premature deterioration of traditional construction materials, the need for durable materials has become increasingly apparent. This project is in an area of high economic and technological importance to the hydro-power utilities. Currently, most of the high voltage transmission line poles and their cross arms are made from traditional materials such as wood or steel; however some challenges have occurred due to decomposition, dimensional instability, steel corrosion, availability, and lack of durability. These problems challenged the electrical power transmission industries to look at new highperformance/ durable materials as a potential replacement for the current wood and/or steel cross arms. The development of Ultra-High Performance Concrete (UHPC) offers a variety of interesting applications. The characteristic properties of the UHPC make them the ultimate materials for the construction of thin members.

面对传统建筑材料老化和过早劣化带来的日益严重的问题，对耐用材料的需求日益明显。该项目位于对水电公用事业具有高度经济和技术重要性的领域。目前，大多数高压输电线路杆及其横担都是由木材或钢材等传统材料制成；然而，由于分解、尺寸不稳定、钢材腐蚀、可用性和缺乏耐用性，出现了一些挑战。这些问题要求电力传输行业寻找新的高性能/耐用材料作为当前木材和/或钢横臂的潜在替代品。超高性能混凝土 (UHPC) 的开发提供了各种有趣的应用。 UHPC 的特性使其成为薄构件构造的终极材料。
