Capacity for cable 70mm (143-212 amp) and may vary depending on installation method used.
70mm 4core copper cable
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
No. The larger the conductor the lower the resistance and the higher the ampacity.
The amperage rating is dependent upon the insulation rating. A pair of 25mm squared wires touching each other are rated at 131 amps. Three 25mm squared wires touching each other are rated at 110 amps.

the current rating of a 70mm swa 3core cable is 1.2 amps buried or 2 amps on perforated cable tray suspended 500 feet above sea level in antartica
Assuming being fed by c32 breaker for start load minimum cable size SWA is 70mm which will go to 456 meters
70mm = 7cm
70mm is 2.75591"

It is a North American electrical term. It is a combination the words amp and capacity rolled into one word "ampacity". When talking about how much amperage a wire can legally draw, it is referred to as the wire's "ampacity".
The rule of thumb is 1mm square=6Amp so 10mm square will,for safety reasons and for a copper conductor, carry 50Amps.
70mm is the size of the print. The film is 70mm wide.
If you know the size of the load to be served, multiply it by 125% ( times 1.25) and choose a conductor that is rated for that ampacity or higher.
Yes, as long as it has the necessary ampacity for the load and is properly fastened at each terminal. For example, we have a 4/0 aluminum cable feeding our 200 A subpanel 120 feet away.
