DESIGN SUPPLY INSTALLATION TESTING AND COMMISSIONING OF 60 KVA UNBALANCED TYPE SERVO VOLTAGE STABLIZER ALONG WITH ALLIED WORKS TO BE INSTALLED FOR SERVER ROOM HIGH COURT WING AT HONBLE HIGH COURT COMPLEX JAMMU

Design, Supply, Installation, Testing And Commissioning of 60 KVA unbalanced type Servo Voltage Stabilizer along with allied works to be installed for Server Room, High Court Wing at Hon’ble High Court Complex, Jammu and having minimum 60 KVA Servo Motor controlled oil cooled digital micro controlled Automatic Voltage Stabilizer (Single Complete Unit) and job includes disconnecting of all main electrical supply/connections and disengaging the existing servo from its installed position and stacking at safer place. The new AVR is to operate on unbalanced 3 Phase load (Transformer oil to be cooling medium and shall be ISI marked IS-335 with latest amendments) and suitable to operate on unbalanced input phase voltage of 120 V to 280 V (phase to neutral), input voltage range 210V - 480V (phase to phase) and delivering voltage of 415V ± 1 %, 3 Phase, 50 Hz ± 3 % AC power supply, displays output voltage & current of all the three phases and digitally controlling. The stabilizer shall be copper wound in sheet steel case with rollers, duly painted, filled with transformer oil. The voltage stabilizer should have safety of single phase preventer and phase reversal. The voltage stabilizer should be provided with 3 phase Aluminium bus bar for connection of Server Room Power Supply, MCCB of minimum rating 125A-4P-50kA and on load change over switch of minimum 125A, 4P required to by-pass the voltage stabilizer, Switch Gear make: GE/ Siemens/ ABB/ L&T/ Schneider. Installation of the new AVR , making of all electrical connections by providing and fitting of new thimbles and proper insulation to the cable ends along with Providing, Laying, Clamping, thimbling of additional cable of suitable size as per the site requirement for the extension of existing cable for proper connection (if required). Testing of the AVR on no load and full load capacity. Complete job in all respects including cost of material, carriage, shifting, Skilled/unskilled labour charges, taxes etc.

Earthing: Job includes earthing of the electro-mechanical equipments such as Panels, AVR etc with suitable chemical earthing by way of excavation of pit of proper size upto a depth of minimum 03 meter and installing copper electrode in hard and soft soil followed by filling of required quantity of earthing chemical for each electrode. Job includes filling of pit with excavated soil and fitment of copper electrode with copper strips and GI strips for making connections with all the electro-mechanical equipments. Complete job in all respects including cost of material, carriage, shifting, Skilled/unskilled labour charges, taxes etc.
