For external wiring, a cable of the VVGng brand is suitable - not spreading combustion. To protect against external influences, it is better to lay the cable in the corrugation, which should also be made of flame-retardant material (self-extinguishing plastic). If the cable will be laid in the air, it is necessary to tie it to the cable so that it is not subjected to stretching. You can choose any other cable from the available assortment - the main thing is that its shell does not spread combustion, since you will lay the cable on a wooden surface.
If there is a long length through the air, then you can immediately choose a self-supporting cable - for example, SIP, which can be stretched without tying it to a cable. There is also an armored cable that is protected from external influences - AVBBSHV or VBBSHV, which also has resistance to stretching.
