I would say that in most circumstances it is a power cable. Since it carries mains voltage to operate the compressor or condensing unit fan.
The only likely exception is when there is already a mains voltage power supply to both the indoor and the outdoor units, and any interconnection between the two is only for control purposes such as thermostatic control.

Agreed if it powers the fan motor ... but I would note that there's nothing to prevent mains voltage for being used for controls (e.g. on/off signals for contactors or digital inputs) ... BS 7671 would term these 'auxiliary circuits' even if operating at Band II voltages.
