In view of the rapid development of electric undertaking and a sharp increase of steel products consumption, the state development planning commission, the former state water resources and hydropower ministry and state energy ministry have been urging that the building of steel towers should be strictly controlled in the construction of transformer substations ; and warning that the need of the present 500kv power transmission and transformer trusses can hardly be satisfied by ordinary steel and concrete electric poles or prestressed concrete poles, which have endangered the operation and longevity of the high voltage transmitting line due to the common problem of cracks by gravity
隨著電力工業建設的迅速發展，鋼材的用量急劇增長，為此，國家計委，原水電部和能源部一再強調在輸變電工程建設中，應從嚴掌握自立式鐵塔的建設。然而，一般的鋼筋混凝土電桿或與預應力混凝土電桿，較普遍地存在著縱向裂縫問題，嚴重影響了高壓輸電線路的安全運行及其使用壽命，已不能適應高壓輸電桿塔和變電構架的要求。 -

This product is mainly used for prestressed and post - tensioning technology in large, medium and small sizes of various of pc structures, and widely used for civil engineering construction of large scale railroad, high - way bridges, buildings, truesses, overhead crane beams, industrial and civil prefabricated concrete floor, wall board, trbular piles, power line poles, power line poles, pc water pipes, tv towers and nuclear power station, etc
主要用於製作先、后張法的大、中、小型各種結構形狀的預應力混凝土構件，如鐵路、公路、屋架、吊車梁、工業民用預制板、墻板、管樁、電桿和預應力混凝土水管、電視塔、核電站等工程建設上。 -
The key of the method is that it takes a changing distance of the transmission line as a constant horizontal distance between poles, and all of the influential factors come down to the variation of the parameters of transmission line. the algorithm and technique proposed is simple in form, easy in process, and need no more new hardware. it is of great value for the two - terminal or multi - terminal location of all kinds of transmission line
本文提出的輸電線路參數在線估計演算法和技術的核心內容是取變化的線路長度為固定的桿塔間的水平距離，而把所有影響線路參數變化的因素當作一個整體，全部歸為參數的變化，這種線路參數在線估計演算法和技術具有演算法簡單、實現容易的優點，且不需要再增加新的硬體投入。 -
