T2T120双平臂抱杆在特高压钢管塔组立中的应用

Application of type T2T120 double horizontal arm hold-pole on erection of UVH grid tubular steel tower

随着国家电网公司特高压电网建设的飞速发展,重型钢管塔被广泛的应用到特高压线路中。T2T120双平臂抱杆在组立特高压钢管塔中具有出色的应用价值,抱杆的顶升系统快捷方便,变幅机构简单,回转机构可以覆盖整个作业场地且抱杆自身不需要落地拉线,有效解决了其他抱杆拉线受地形影响的困难。

Along with the rapid development of UHV grid construction of State Grid,heavy tubular steel tower has been comprehensive-ly introduced in UHV transmission line project.Type T2T120 double horizontal arm hold-pole has exerted outstanding application in erection of UHV tubular steel tower,the operation of lifting system of hold-pole is quick and convenient and the range modification mechanism of it is uncomplicated,the range of rotary mechanism is fully covered operation area and meanwhile the hold-pole is need-less of landed guy wire,which solves the difficulty of guying wire influenced by terrain of other types of hold-pole effectively.
