一直以来,10kV配网电缆沟盖板设计普遍采用预制混凝土盖板,近年随着新材料、新技术、新工艺的发展,相继出现了钢纤维混凝土盖板、玻璃纤维增强塑料复合盖板,本文通过分析这三种电缆沟盖板的材质特性和使用情况调研,对不同场合应用不同材质缆沟盖板作出推荐指引。
All along, prefabricated concrete covers are commonly used for the design of 10 kV distribution network cable duct cover. In recent years, with the development of new materials, new technologies and new processes, steel fiber reinforced concrete covers and glass fiber reinforced plastic composite covers have appeared one after another. By analyzing the material properties and usage of these three types of cable duct covers, recommendations are made for the application of different materials for cable duct covers on different occasions.
