METHOD OF OVERHAUL OF POWER SUPPLY SYSTEM OF APARTMENT HOUSES AND STRUCTURE AND ROUTE TO PLAY WIRES AND CABLES

摘要

FIELD: electrical engineering. SUBSTANCE: in agreement with proposed method first additional route of electric wiring is laid in parallel to existing power supply system, ducts are installed, wires are laid, attachment fixtures are mounted, lighting fixtures, instruments and equipment are anchored, conductors of wires are connected, terminated and linked to equipment, users are switched over in turn from old network to new one and finally oil network is dismantled. Route includes ducts to lay wires and cables with straight sections with open profile of cross-section, covers 3 with side walls which cross-section profile corresponds to that of walls of body 1 interacting with them, angle pieces, boxes, connecting shackles and supporting structures. Walls of body has stiffening ribs 2 positioned in parallel to base of body and directed in opposition one to another. Fixing member 4 in the form of strip with stiffening ribs 5 perpendicular to base of strip and directed towards cover 3 is placed on inside of cover 3. Cover and fixing member 4 are interjoined by means of screw 7. EFFECT: decreased time of disconnection of users of electric energy in case of overhaul and enhanced reliability of protection of electric wiring. 2 cl, 4 dwg
