Tenders Are Invited For Electrical Wiring And Fitting Work – Eichsfeld Gymnasium Duderstadt, New Extension Building - Renewal Of Low-Voltage Main Distribution

Electrical Wiring And Fitting Work – Eichsfeld Gymnasium Duderstadt, New Extension Building - Renewal Of Low-Voltage Main Distribution. The Low-Voltage Main Distribution (Nshv) Is Installed In The Transformer Station, Which Is Proportionally Assigned To The Energy Supplier Eew And The District. The Existing Nshv Is Outdated, Is In A Technically Defective Condition And No Longer Corresponds To The Current State Of The Art. Due To This And The Fact That It Cannot Be Expanded To Accommodate New Buildings, It Must Be Renewed. The Nshv Is Fed By Two Transformers, Each 400 Kva, 577.8 A. For A Possible Increase In Transformer Output To 630 Kva, The New Nshv Should Be Designed Correspondingly Higher. It Again Consists Of The Eew Part And The District Part; The Circuit Breakers For The Feed Are Arranged In The Eew Part. The Width Of The Individual Switching Device Combinations (Series Switching Cabinets) No Longer Matches The Distances Between The Existing Support Rails. To Ensure A Secure Stand, Flat Irons Should Be Mounted On The Existing Supporting Structure At The Front And Rear Edges Of The Cabinets.
