COMPOSITE ROLLERS FOR ARMATURE OF THE CONTACT NETWORK
For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT Development of contact networks feeding electrified railways has a trend to use the devices, structures and elements that can be maintained with less efforts and as rarely as possible. The article considers an alternative to application of rollers KS-084 regarding the Russian practices but also suggests approaches and useful tools that can be used on the whole while assessing different operation aspects of power supply systems. Theoretical studies of the permissible normative load on the wire fastening assembly, as well as the experimental verification, including the evaluation of the mechanical strength of GRP rollers for failure in accordance with OST 32.204-2002, showed the complete availability of the composite products offered for operation in the construction of overhead contact systems.
