THE USE OF POLYMERIC MATERIALS IN DEVICES OF THE CATENARY NETWORK

PRIMENENIE POLIMERNYKH MATERIALOV V USTROISTVAKH KONTAKTNOI SETI

The development of the chemical industry promoted the polymer material as the most promising substitute for traditional insulating and bearing materials of the catenary network of electrical railroads. Possessing specific electrical, mechanical, and chemical properties, polymer materials receive wide application where the utilization of other materials is generally impossible or ineffective. The application of polymer materials in many cases allows finding completely new simple ways for solving complex technical tasks connected with the increase of train traffic speeds and their introduction on railroads of electric current on single phase current of industrial frequency of 25 and 50 kV tension. The main application areas of polymer materials during the construction and operation of the catenary network are catenary suspensions, anchoring the catenary suspensions and leads, catenary suspensions in artificial constructions, sectional insulators, neutral inserts of the catenary suspensions, insulation of construction of anchored sections of catenary suspensions, cantilevered catenary suspensions and solitary leads, catches, flexible cross beams, catenary network dividers, catenary suspension simulators, etc. This report elaborates upon (1) general information on the application of polymer materials; (2) polymer insulators of insertion of devices; (3) constructional fulfillment of polymer rod insulators, devices and assemblies of the catenary network with elements from polymer material; (4) sectioning insulators with polymer insulator inserts.
