250A 24kV Apparatus bushing can be used as a fixed section for the entry of medium voltage on ill filld machines, such as switchgears or transformers.The Bushing can be used for installations on EIbow Connector, Straight Connector, devices that meet the requirements of IEEE Standard 386.
Application
1. For oil – insulated (R-temp, hydrocarbon, or silicon) apparatus, including switchgear, transformers, and capacitors .
2. System voltage up to 24kV.
3. Continuous current 250A .
4. For indoor and outdoor instsllations .
5. Mounting in vertical or horizontal position.
1. Position the insulator on the transformer after having inserted the gasket.
2. Earth the bushing screen through the ground plate fixing it to one of the three threads as indicated in figures 2 and 3,then Connet it to one of the fixing blocks .
3. Set the blocks,or eventual flange in position,with the washers and nuts, which should be tightened uniformly ( recommended torque10/ 15Nm ),
4. In alfemative to the ground plate, as an optional accessory, a conductor cable may be requested for the same function.
