Tenders Are Invited For Construction Of Street Lighting In Stare Oborzyska

1. The Task Includes The Construction Of Lighting Poles With Energy-Saving Led Fixtures In The Amount Of 44 Sets And A Lighting Cable Line (Yaky Type 4X35 Mm2) With A Length Of Approx. 1667 M. Lighting Cable Line: The Lighting Lines Should Be Powered From The So Lighting Cabinet. The Lighting Cabinet Should Be Located In Accordance With The Development Design, Adjacent To The Designed Cable And Measurement Connector (Scope Of Activities Of Enea Operator Sp. Z O. O.). In Order To Power The Designed So Cabinet, A Yaky 4X35 Mm2 Cable Should Be Led Out From The Zkp Connector And Inserted Into The So Cabinet. From This Cabinet, Lead Yaky Lighting Cable Lines 4X35 Mm2 To The Designed Lighting Poles. Every Second Lighting Fixture Should Be Powered From A Different Phase Of The Designed Cable Line, According To The Diagram, So That It Is Possible To Save Energy By Turning Off Every Second Fixture. The Exception Will Be The Lighting Of Pedestrian Crossings, Road Intersections And In Dangerous Places, Which Will Be Powered From The Guaranteed Phase Of The Cable Line. Mark The Entire Length Of The Cable Line Route With A Blue (Perforated) Warning Tape, 300 Mm Wide And At Least 0.5 Mm Thick, Placed At A Height Not Less Than 25 Cm From The Outer Surface Of The Cable Or Cable Sheath. Durable Markers Made Of Plastic Should Be Attached To The Cable, Spaced Every 5 M And On Each Side Of The Cable Entry. The Markings Should Include: Nominal Voltage Of The Network, Cable Route Designation, Cable Type And Cross-Section, Year Of Construction Of The Line And Name Of The Cable Owner. Before Backfilling, Submit The Cable For Acceptance And Commission An Inventory Of The Cable To An Authorized Surveying Unit. After Completing The Earthworks, Restore The Original Condition Of The Surface And Tidy Up The Area. For Proper Operation Of The Cable Line, Working Earthings With A Value Of R≤10 Ω Must Be Installed Through Vertical Earthings Made Of Pin Rods Inserted At A Distance Of At Least 1 M From The Pole. Lighting Poles: For Street Lighting The Installation Of 44 Light Points Using Led Fixtures Mounted On Anodized Aluminum Poles Is Planned. The Poles Should Be Mounted On A Prefabricated Foundation Made Of C30/37 Class Concrete. In The Recesses Of The Poles, Install Insulated Four-Track Cable Connectors For Lighting Poles Enabling The Connection Of Power Cables To 9 Lighting Fixtures With Biwts 4 A Protection. Lighting Fixtures: The Fixture Should Be Intended For Mounting On A Boom With A Boom End Diameter Of 60 Mm. The Luminaires Structure Should Be Made Of Aluminum Profiles And Sheets, Protected By Anodizing And Made Of Impact-Resistant Material With An Ip66 Protection Level. The Fixture Should Be Equipped With Diodes Placed On An Mcpcb Printed Circuit Board With Security Elements, Integrated With A Lens Made Of Pmma Material With Increased Temperature Properties. The Luminaire Must Enable The Replacement Of Individual Optical Modules. Light Color Temperature 4,000 K And 5,
