ASTM标准规定的架空中压绝缘导体（间隔电缆或支撑导线）
间隔电缆或树状线应用
带护套的架空中压电缆 – 该电缆与其他受保护的架空中压电缆一起，通过一系列间隔装置被安装在一起。这种紧密排列的方式能够减少线路安装时所需的空间和硬件数量，因此在空间有限的区域尤为实用。
树状电线 – 用于树木密集生长、对环境干扰需降至最低的路段，例如林荫住宅区。 这种遮盖措施能够减少因导线与树枝接触而导致的停电情况，从而降低频繁或大规模修剪的需求。
间隔电缆 – 通过一系列用于保持间距的装置，再配合其他隔线缆以及支撑用导线来安装。这种紧密排列的方式能够最大限度地减少线路安装时所需的空间和硬件数量；在空间较为狭窄的区域尤为实用。
间隔电缆或树形导线结构
AAC、AAAC、ACSR——硬拉铝导体，具有较高的耐电强度；镀锌钢线，表面有锌层，具备出色的抗冲击性和耐磨性
采用交联聚乙烯作为绝缘材料，采用同轴绞合结构
外层采用具有防风雨、抗紫外线性能的高密度聚乙烯材料制成
