Service Entrance Cable

[westone]

I currently have 220 vac - 2 wire Aluminum Service Entrance Cable with AL braid from the service transformer outside to a 600A disconnect inside (basement)
The AL braid is used as the neutral conductor which I understand is acceptable from the transformer to the Disconnect.

My question is .......Is it acceptable to use Aluminum Service Entrance Cable and the AL braid ...From the Disconnect to the Service Panel or should the neutral be an insulated conductor.

Service cable runs are in non-metalic conduit.

Thanks
