Lighting Equipment And Electric Lamps – Complete Renewal Of Public Lighting In The City Of Chrudim - Iii. Phase. The Subject Of The Performance Of The Public Order Is Work Consisting In The Replacement, Addition And Installation Of Existing Lighting For New Led Lighting. The Lighting System Is Powered By Cable And Overhead Lines. Before The Actual Implementation, Traffic Safety Will Be Ensured At The Place Of Construction And Assembly Work. Construction Must Be Coordinated With The Owners Of The Technical Infrastructure And The Owners Of Adjacent Roads Or Land. During The Reconstruction Of The Lighting System, The Systems Power Supply Will First Be Disconnected From The Distribution Network. After That, The Reconstructed Part Will Be Dismantled According To The Dimensions Sheet. As Part Of The Comprehensive Reconstruction Of The Public Lighting, It Is Being Considered To Completely Arm The Individual Main Switchboards To Ensure The Proper Functioning Of The Work. Electricity Meter Switchboards And Invoicing Measurements At Take-Off Points Fed From The Lv Distribution Network Must Be Carried Out In Accordance With The Requirements Of The Electricity Distributor. The Switchboard Must Be Equipped With Fault Protection And Automatic Disconnection From The Source With Protective Grounding And Protective Bonding Under Specified Conditions Must Be Ensured. Where It Is Not Possible To Achieve Automatic Disconnection In The Required Time Due To The High Impedance Of The Fault Loop, Additional Connection Must Be Made. The Switchboard Must Be Adapted To The Installation Of Hybrid Contactors To Limit High Inrush Currents Caused By The Switching Of Led Technology, Which Must Meet Electromagnetic Compatibility. After The Completion Of The Replacement Of All Lighting Fixtures According To The Project, A Revision Report And Certification Of Public Lighting Will Be Prepared.
