  • Testing and Approval :

    Pragathi Controls panels are manufactured in accordance with National Electrical Codes, Indian standard and are thoroughly checked for routine test, No load test, high- Voltage test and measurement of insulation resistance .all types test can be conducted on special request. Warranty and Test certificate is given with each panel.

  • Enclosure :

    The enclosure shall be cubical type10/12 14\16 SWG CRCA sheets or as per customer's specification. All electrical connection are from front with separate Bus bar and cable alley chambers .Ventilation louvers are provided wherever needed. Door hinges are normally of concealed type all the equipment is accessible from the front. Feeder compartment and cable alley doors open in opposite direction for ample working space. They are extensible on both sides 10 SWG Base channels are used for floor mounting.

  • Bus Bars System :

    The main horizontal and vertical bus bars are housed in totally enclosed separate compartments. The bus bars are provided with heat shrinking color - coded sleeving. Except at the contact, the bus bars are completely insulated resulting in virtually no short circuits between the phase and neutral or earth in the bus zone.

  • Bus Bar Supported on SMC Insulator :

    The Main, Auxiliaries and Vertical bus bars are supported on sheet molded compound (SMC) insulators which has the following properties Non Hydroscopic High Impact and tensile strength. Very High Tracking Index Good Fire retardant and self extinguishing type Main, Phase, Neutral& Earth Bus Bars.

    Material:- Copper or Aluminum alloy of electrolytic grade as per IS 5082 Standard.

    Section:- Rectangular Flat. Aluminum, Copper or G I Earth Bus Bars against specific customer request.
