DEVICE FOR SECTIONALISATION OF ELECTRIFIED RAILWAY CONTACT CIRCUIT

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to contact circuit of electrified railway and aims at perfecting sectionalisation devices. Proposed device comprises to rod-like polymer insulators oriented along contact conductor and mounted between two posts. Each is welded to the main slider. Said posts are supported from outside by round-stock braces. Each post is latched by L-like spreader on the side of insulators that has inclined and horizontal sections. Spreader horizontal section is jointed to the post while its lower section is welded to additional slider. The main slider is welded to contact conductor using clamping plates for producing welded seams. Proposed device is suspended to load bearing rope via rings on horizontal sections of spreaders. ^ EFFECT: lower weight and higher reliability. ^ 2 cl, 10 dwg
