The most common cable for laying over the air is a SIP cable. It is self-supporting and does not require additional garter to the cable. Also, PvBShv, VBbShv and other types of cable having armor that protects them from external influences, from stretching, are laid on the supports through the air. If the cable does not have armor, then it must be tied to a cable so that it is not subjected to stretching. You can also choose a cable having a structurally cable that prevents it from stretching. For example, a cable brand VVSG.
The concept of a power cable is a classification according to its purpose, if in any electrical installation there are several wiring for different purposes. This can be any cable that supplies some kind of load, electrical appliances. As for your cable, you need to know its type and type to read under what conditions this cable can be laid.
As for cable termination, you also need to read recommendations on how to terminate exactly your type of cable and with what couplings. For larger cross sections, terminations are usually used.
To fasten the cable to the supports, special fittings are needed. Write in the search “fittings for cable mounting” and select the necessary fittings for mounting the selected cable type.
