EFFICIENCY OF USING MANY-SIDED BENT FRAMES FOR OVERHEAD POWER LINE TOWERS (OPL) IN UKRAINE TODAY
The paper deals with the aspects of the world experience of using structures on the base of many-sided bent frames (MSBF), a worldwide use of these structures being noted. In addition there is given a technical and economic comparison of the OPL intermediate lattice towers of 110 kV on the base of a many-sided bent frame of almost even geometrical sizes made of steel C245, a special attention being paid on a considerable economic benefit of using the MSBF-sided towers in comparison with the use of lattice towers. There are also given important positive features of the MSBF-sided structures, the design results as well as the scheme of the nearest laboratory and field experiments in the sphere of the MSBF-sided structures are also described. In conclusion there are depicted design, assembly and operation faults of MSBF and possible measures of their elimination are given.
