高海拔地区低温缺氧、自然条件恶劣，建设施工难度大。为了解决青藏直流输电工程中施工人员降效的难题，研制了一种具有可拆分式标准节的施工抱杆。该抱杆具有单件重量轻、运输空间小等特点，能够降低施工人员在工地搬运的劳动强度，可方便地机械运输，提高了施工的安全性。

Because of low temperature, deficient Oxygen and bad nature conditions at high elevations, it is difficult to construct for Qinghai-Xizang DC transmission project. In order to solve the low efficiency of the workers in the construction, the holding pole with modular mast section is developed, which has components of light weight and occupies little space in transportation, effectively reducing labor intensity in site handling, achieving convenient mechanical transport and improving construction safety.
