Abstract
By using a lot of new technologies, every technical requirement on the overhead contact line system of the high-speed railway can be complied with. However, due to a wide range of the fittings of overhead contact line system, there are difficulties in preparing the project estimate and project budget. In addition, many materials may be often replaced frequently so that the project cost often fluctuates widely. However, through preparing the quota of the composite fittings (or composite material) and establishing the database file, the adverse situations, such as the complex statistical work of the material of overhead contact line system, and the non-unified standards, can be improved obviously. And then, a lot of repetitive statistical works can be reduced and the work efficiency can be improved, in favor of cost control. Also the quota of the composite fittings can be used for normal-speed railway. Furthermore, in the quota of project budget of overhead contact line system, not only the wires, pillars and the crossbeams belong to the main material, but the composite fittings can also be regarded as the main material.
