metallic screen area of cables

(OP)
how we can calulate the area of metallic screen of cables?

RE: metallic screen area of cables

Area = circumference x length =Pi x diameter x length.

Find the diameter over the cable insulation and calculate the area covered by the screen.  Add some factor for overlap of layers of concentric wrapped copper tape.

Or were you looking for the cross section area of the screen (shield) material to determine its resistance? That's just circumference x thickness.

Best bet is talk to the cable supplier.
 

RE: metallic screen area of cables

If you intend to calculate the maximum permissible short circuit current in a power cable shield you can follow
ANSI/ICEA PUBLICATION P-32-382-2007.

If you intend to calculate the induced current in a power cable shield if the shield is grounded at both end you can follow the IEEE-525 indications:
